Subaru WRX Brake Caliper Perfect Restoration

- Welcome to this weeks restoration. Today i am tackling the restoration of an old pair of STI 4 pot Sumitomo calipers for my WRX seeing as the Brembo's arent suitable for my goal ( Link here - • 25 Year Old Brembo Bra... ) So the plan is to fix the rust, clean up the castings, paint them, rebuild them and fit them to the car so lets crack on with the work.
First things first a visual inspection to check for defects or any major flaws that would render these calipers unsuitable for restoration and im pleased to say they are in good shape apart from being a little seized from sitting around for years.
The first job is to strip the old brake pads and fitting kit out this was simple enough and the pins weren't too seized. After the pads were out i set up my pressure regulator to around 50 psi and blew the pistons out with compressed air making sure there was wood in between them to cushion the impact as the pistons could chip and send dangerous shrapnel flying around the room.
After the pistons were removed i separated the two caliper halves with the help of my Snap-On impact gun then headed over to the parts washer to remove years of brake dust, brake fluid and general road grime this step is necessary to prolong the life of the blasting media and stop the blaster from clogging up with lumps of crud.
Once dry the halves were loaded into the blasting cabinet and given a good blasting this removed all rust and corrosion from the surface of the steel and left me with a pristine surface to paint onto.
After blasting i re-assembled the calipers so that i could grind away the rough casting marks left at the factory and smooth he calipers out so they would appear to be one single piece. This worked out successfully and allowed my to go to the next step which was as usual etch priming the surface preparing it for a following coat of high build primer.
The primer was left to cure them was wet flatted to give a flawless surface to apply my base coat red onto. Once the base coat was applied i made up some Subaru decals with my plotter and white vinyl and applied them in the appropriate location then gave them a good coat of clear to protect them.
While the clear coat was curing i set about re-plating the bolts as they were still in perfectly good condition all they needed was a little rust removal and a new coating of zinc and yellow passivate and they are good for another 20 years at least.
After all that it was simply a case of fitting new pistons and seals and joining the two halves back together with loctite and the correct torque this was verified by using my fully calibrated Snap-On torque wrench.
And there we have it one set of calipers all ready to be fitted and to do some serious braking :)
Which so you prefer the Brembo's or the Subaru's? Let me know in the comment section.
As always i hope you enjoyed this video and i'll see you again soon with another episode.

Perfection. I see others try this, and fail to protect machined parts from sand blasting. They use the wrong fluids in the wrong places. Your efforts to prevent cross contamination are second to none, in the UA-camverse.
Thank you so much for your kind comment :)
Yeah, but just a shame most people watching doesn’t have a Scooby what the F the fluids are pal
for the smaller passages i think ear plugs would be a great fit, just roll them up like youre putting them in your ear and then pop them in to the threadi g
This is the most rewarding video I have watched. There's just something about being able to fully restore something, and the process that comes with it is so satisfying.
Thank you, Glad you enjoyed it :)
George had his mask on and was social distancing lol. Once again, a perfect restoration!
You should definitely do a how to ‘re-plate’ at home video👍.
Been hoping for one. Want to learn so I can try to replate some vintage watches.
@@ro63rto Go to Cameron Niemelas UA-cam channel he did a very specific guide how to plate bolts.
Best resto channel on the tube, Squire. No fake rusted up shite, just good old no nonsense, real life work.
Thank you so much :)
Why would someone give thumbs down to a video like this? There's no complacency...
Subaru owners who don't have the BBK. Fk em.
FOCUSST cause mibbies most folk don’t have a Scooby what bloody fluids he used ?
Only idiots....
I can only think of a couple reasons, mostly because the brakes were perfectly fine before "restoration", although they were dirty and a little ugly. And some people don't like painted calipers because the brake pads can get so hot that cheap paints flake off like dry skin.
@@shippo72 what about powder coated?
I definitely prefer the Subaru livery, they came out perfectly. Ill never tire of watching you plate parts, always so satisfying :)
Absolutely beautiful 👌🏻
holy shit my two favourite youtube channels and one just commented on the other ones video
Thank you very much , Always a pleasure to see you in the comment section :) I see that your Fiero project is coming along nicely 👍
The Brembo brakes came out great but the Suburu's have more style! Great job on both though!
I totally agree! :)
The attention to detail was extraordinary, reflected in the finished product.
Nice to see George wearing his mask! Nice work 👍🏻
Thanks! 👍
Just tore the 4/2 pots of my WRX this morning to rebuild. This helps a lot!
What torque specs did you use for both?
60NM for the connecting bolts
Nice job. Anyone doing this at home you should use stainless pistons. The nickel whatever coated ones will stuck in a year. Also neat trick you can do is instal those pad pins backwards and do a cool aviation style locking wire setup on the outside.
Awesome job again mate .i honestly couldn't choose between the 2
Would have to eye them up on the car 🤷♂️
Thank you :) Yeah they are quite difficult to choose between
Master of your craft sir. The amount of work that goes into restoration, then the filming and editing. I'd buy you a few pints.
Amazing work , i have a jdm wrx myself and am thinking of restoring it
Perhaps this video can be used to teach how perfection is achieved. Great job.
What’s the torquing specs for the bolts? Beautiful job by the way came out looking better than before!
Damn, those are better than from the factory! I'm a Brembo fan, but the Subaru logo looks very nice. Excellent work.
Thank you very much :)
now i regret selling my top to toe V4 Type R restoration now...that said, Ive just bought a pair of knackered calipers and plan to restore them for my R53 big brake kit mini cooper project! thanks for the inspiration.
Well done Mr. Random. It’s also interesting to see your editing skills evolve over time. 👍
Thank you very much :)
the patience you have is phenomenal great work mate 👍
Thank you :)
Did this myself about 2 months ago, rear 2 pots too, didn’t sandblast or etch primer them but they Turned out pretty good imo
Beautiful job, and they look much better with "Subaru" vs "Brembo"
"They" are two different brake calipers.
I had front and rear wrx brakes on my Legacy wagon.
Machined both down, to a smooth finish, and placed "LEGACY" on the front ones (similar as original) and the jdm "L" from the Legacy's of the time.
Miss that car.
Now that’s sympathetically restored
Wow! You've done an absolutely marvellous job restoring those Sumitomo WRX calipers. Two thumbs up!
Thank you :)
Great camera work lots of close up details thank you
Great video. If you release the spring clip first, the pins can be easily removed without a punch normally.
Beautiful resto of those grubby ole calipers, now look out of the box brand new!
You really brought them back 👌😎 support from Las Vegas
Thank you very much :)
They look great! Go with the Subaru calipers 🙂🚗
Stunning restoration of those calipers. It seems a simple process but very exacting. You definitely have to know what you are doing. 👍🇦🇺
Loved the plating in particular, but the whole video was so satisfying. Personally I prefer the sumitomo (subaru) calipers, since they fit under 15s.
Thanks for leaving a comment :)
Simplest things always look good when you restore them....Oh, and it's always about having the right tools to do the job. Nice video, very therapeutic to watch!
Thank you very much for leaving a comment, very glad you enjoyed watching it :)
Suburu?
Impossibru!
Great job, I would use powder coating as it’s more resistant to heat
Thank you :) , Ive always preferred paint over powder coat though.
Excellent viewing. Nice job.
Thank you :)
When fitting pads, the use of EBC Redstuff will drastically reduce the level of brake dust produced that will spoil the finish on the calipers and wheels. They give great performance too........they're the only pads I ever fit to my Impreza.
man, you are an artist... I would like to have you and your equipment locked in my garage with my Mazdaspeed6 for a few months... not to worry though, I would feed you...lol
Haha well its good to know i'd be fed at least haha Thanks for leaving a comment :)
It's commendable that you take care of George's health but he also needs to feel that he has a higher aim in life.
Wow. Unreal !!
Beautiful job !!
Man you have all the right tools !..
Love for you to work on mine !!
Nice... I am inspired... I will be doing this to my 4Runner brakes...
Those of subaru look safer because they have the distribution of fluids inside the calipers .. those of brembo are on the outside which may be more prone to leaking
So amazing!!!!! Perfect job man! You have tons of patience!!!
I think Brembo is better, but I just love the way Subarus´s calipers looks like!
This caliper set looks just alike the z32 sumitomo set, im restoring mines... any chance you have a video for the electronic plating process for the bolsts?
Wow both are stunning but i do prefer the Subaru's. Great watch.
You have some serious tools at your disposal. The machine for cutting the sticker out haha! Love it. I have alot of kit myself but in a 1 car garage Ive got no room to moving making any task under the car a damn nightmare. Amazing channel mate. You have a new subscriber! Keep them coming.
Another amazing video!
Love from India 🤘🏻💕
Nice to see you again, Glad you enjoyed it :)
both of them looking awesome I prefer Brembos for front, Subaru ones for rear 😋☺
haha if they would fit under the rims i would certainly consider it ;)
Good to see george being safe! Haha I havent watched all of it yet but I already know these are going to look gorgeous. I stayed motivated from the last Subaru video and gutted my forester interior the other night and deep cleaned all my carpets, removed the seats and shampooed them etc. So thanks for the motivation mate :)
Nice, I cant wait o finish the mechanical work and give the GC8 interior a good deep clean aswell its absolutely filthy haha
@@RRCRestoration its so satisfying!
What was the torque settings for the casing bolts
Such an awesome video… loved watching it . Gunna try my own now
What torque spec did you apply?
Every video makes me want to stop being lazy and paint my bike frame, yet here we are. 😜
So jealous. If only I had the equipment and space you have at your disposal
I respect the level of work, but since I don't have the ability to do half of what he does I settle for a spray can paint job and new bolts/pins/pistons. One day I'll get there!
Subaru calipers, because I have them. Nice video Bro, great job.
It would be nice if you listed the fluids used, the proportions, the sequence and times in each of the various fluids. Also after the etching primer, what was sprayed on before the final red coat? Some of us would like to learn.
these look bloody great... what a piece of work... awesome...
Thank you! Cheers! :)
Wow this is perfection. Like the scene in Rick and Morty where Morty experiences true level, I'm Morty.
Hi my friend 👋👋👋 your clear and impeccable restoration work always inspires me, respect to you 🤝👍👍👍🔥✌🏻🇷🇺
Thank you so much :)
Yapıyorsun bu sporu
you should of cerakoted them bud alot higher heat protection on that and gives a nice finish
Probably not necessary. The calipers themselves, if I’m not completely mistaken, don’t actually conduct that much heat from the pads. The pads are designed not to conduct heat, rather, they heat the rotors.
I really fancy trying cerakote at some point on some of my motorcycle restorations as it looks like a great product. The calipers will be fine as Brady correctly said the actual calipers themselves dont get that hot if they are working correctly, dont forget there are rubber seals in the caliper so if it gets hot enough to melt paint then its more than hot enough to ruin the seals aswell ;)
Really Random Channel keen point on the rubber seals.
@@RRCRestoration yeah we had brake fade after 3 laps when it dryed up but thinking of cerakoting my intake plenum on my p38 nice burnt bronze or somthing or my cr125 calipers and bits
I absolutely need to restore mine !!! Awesome work!!! Did you use a high temperature primer and paint or a normal one? Would be great to have the links to the products used!
You didn’t check the breaking calipers’ cylinders. Should I hohn them (remove any minor scratch from the old breaking cylinders) as leakage prevention before putting in the new cylinders in?
Your videos never fail to amaze, keep up the good work!
The mounting holes on these also happen to use aluminum inserts and the bolts are steel which will cause the bolts to seize up over time. It'd be nice to have an easy solution.
I just purchased a white FRS and I am so hyped to start doing all these things to parts on the car. Been watching you for a long time and even got some questions answered from you when I was repainting the wheels on my Lancer
Nice, Glad i could help you out ;)
I like the Subie more!
Once again, lovely work, top job mate, always look forward to your videos, 👍👍👍👍
Thank you! Cheers!
Very nice job! I appreciate your work!
PS: i have no SUBARU, I will go with BREMBO 😉
Excellent job mate, they look great. Thanks for sharing. Cheers
Thank you! Cheers!
Brembo, this is beautiful
Torque for connecting bolts is 60NM
Very impressive lad, as always excellent work, looking forward to seeing more
Nice to see you, Glad you enjoyed the restoration :)
Amazing. Was thinking why clamp it at end onto paint? But I'm did
I would like to see more please lol. Both Subaru and Brembo looks amazing but would prefer the brembo on my subie as i have tested them both and got great stopping power with it. Love the vids, keep em coming ama keep on liking em cheers..
Smashing result. Can I ask what cleaner you use in your parts washer? Even a deep clean made them look a lot nicer. Granted the respray made them look like new. Subarus look nicest, Brembo is just a bling fad unless it came with them from the factory, more important that the caliper is well maintained and fitted with decent pads imo
Great work , it would be better to Polish those logo and clear coat it or paint than stickers
Another great resto video. Did you use a high build primer & 2k lacquer? Would be very interested to see a plating video like you do for bolts/brackets etc, including how long the fluid will keep before replacing it etc 👍
Superb
Thanks 🤗
Great video, Ive been restoring them this way for a long while.
Any chance of a closer tutorial on the bolt restoration, zinc plating etc as I have always replaced the fixings at additional cost, when they turn out as good as new I would rather do as you have. Cheers
nice job pal
Brembo for the win!
Looks like a perfect job to me.
Thank you :)
You are the BEST !!!!!!
You only need to place the 2 types of paint that you put on the caliper after painting etch primer, please help us with that answer
They look great but is it OK to put a vinyl sticker on calipers which will get very very hot,,????
Great job, I hope to do a good job for my alfa romeo 156 calipers !!
Con todo ese equipo hasta la abuelita de Batman
Look OEM, outstanding job
Thank you :)
Can I ask you if you still have the template for the vinyl, and if you’d share it somewhere? I’m currently cleaning up some of these brakes and would love to run it through the wife’s Cricut.
Beautiful, beautiful work on these.
Better then new!
Thank you :)
My 4 pots I rebuilt never came with a metal ring around the piston seals.
They should have, as the snap ring is what holds the rubber seal onto the collar and prevents the seal from lifting as the piston pushes out.
@@RRCRestoration The old seals never had them either. It came off my version 4 STi.
It may depend on the design of the caliper? I rebuilt a a 1999 Suzuki brakes with new seals etc, and it didn't have metal rings either. Pretty sure my car, a mazda does, but I'm not 100% sure on that.
The Scooby calipers look the best to me, but the Brembo's look damn sexy too. Ah heck, everything that comes out of your workshop looks sexy!
Good to see George getting wise and using PPE. I do worry about him sometimes.
Nice to see you :) Thanks for leaving a comment, Glad you enjoyed it. Yeah he usually doesnt bother too much about what he breathes in but this virus has really got him spooked haha.
perfection in your hands and works, it is formidable congratulations, a good question two. before you give the first you give it black paint that is ?? and the second can be varnished on top of the sticker, nothing happens to him. Thank you fantastic video.
BTW, did you remember to put both o rings in for the caliper halves this time? :)
