This is the proper way to do this. Complete disassembly, thorough cleaning of the components, correct masking of contact surfaces, then high heat paint applied and cured. Agree with those who say to chase the threads to prevent galling upon reassembly, and possibly honing the piston bore if needed. Overall, very well done.
2:20 lemon acid you mean citric acid?? It works with more metals or its specified for some metal?? i would like a bit explanation since i have many parts that i always sand by hand because i dont have sandblasting machine.. it will be really usefull to have more time while the chemicals working.. thanks you!!
Excellent work. Never thought of Lemon Acid and it's ability to remove rust from calipers. You used Zinc Primer, then a black paint on the mounting surface. Is that just black heat-resistant black paint as well? Thanks again for this how to.
Nicely done job! It was good to see the use of citric acid, because that's a great way to remove rust and I've never tried that, with a caliper, so far.
A strong vinegar solution overnight is the best I've ever used. It must be done outdoors, however, because of the odor of vinegar, which is likely unhealthy to breath very long.
Those slider pins you should only use silicone based grease, if not they will dry up against the rubber slider pin housing it goes through. The rubber housing have like 3-4 pockets inside where silicone grease should fill up all available space. What he sid with the piston is fine, you will bleed the brakes with new dot4 brake fluid after mounting, this will be lubing the piston for years untill dust particles gather up and lock up the brakes again.. I have rebuilt the same brakes on my VW
Good Video :) I always apply high temp ceramic grease on inside threads to stop steel bleeding nipples sizing up. And use ATE assembly lube on seals and pistons itself. Also if u want them to last lot longer than zinc plating is best rust prevention and than powder coating or Epoxy primer and spray it.
Nice job 😎 I recognise those calipers - same as on my Volvo, though I wouldn't brave disassembling them at my desk like that 😵 Very surprised how well boiling in citric acid worked - I might give that a go 👍
Some of the comments here are just crazy. The small mindedness is incredible. Our world is full of this. What chance have we got….This is great what he is doing. Well done.
If you watch closely, you'll realize there's 2 of them for both sides of the car, they are symmetrical, so there isn't any mistery you were just looking at the same calipers from differents sides of the car. I think that would be pretty clear tbh, because you can see both in the video.
pressure release on the break piston can be achieved with pressured air. Be carefull though, use low pressure and as in this video, a cloth to brace the exit of the piston.
Yes, good vid. If you don’t have a sandblaster, here’s my poor man’s substitute: one of those massage ‘guns’. I got a small diameter (1 inch ish) wire brush head, meant for use in a drill, and i had to increase the diameter of the shaft of it from the standard 1/4” to around 10mm or so. Now you could just wrap say, a cut-off segment of a hose pipe, and keep going until you get it about right, then apply duck tape or insulation tape with some tension, to hold it in place. I have a bag of short lengths of clear plastic tubing various sizes, that neatly are a press-fit into their next size up or down, you know what I mean. It took three of those, about 1” lengths, shoved over one another. It was easier to give it a try, then remove all of them, and assemble the chinese-doll arrangement of three stumpy bits of tubing OFF of the rotary wire brush, THEN bang them on with a hammer gently, and yea, wear gloves here. Then, it fitted the mounting hole in the ‘gun’ pretty well, all these things are just push-fit anyway on my unit. How well does it work? Pretty well. I got the one that is most compact, I didn’t go for max power or size or anything, I just got the one that had a decent Temu star rating. It’s got gold edging on it, if you are looking. It was less than £10UK . I used it on my Prius rear brake caliper, and it took the rust off better than the alternative, hammering with a small weld-flux removing hammer, or hand wire-brushing or rotary wire brushing. There’s still a use for rotary wire brushing, my main issue is, I don’t want to damage my drilling device, Bosch or Milwaukee, neither surely has bearings designed for that much axial loading? Anyway…while this does not take the rust down to the metal, it’s as good as any of the other non-laser or non-sandblasting methods, and easier. And the lack of out-of-control rotary whooshing wire bristles is nice too. My particular massage gun, has 6 power settings. But, in addition, it has a sort of ‘pressure-activated-boost’ action, and this is proportional to the power setting you are on. IE push down harder on setting one, and there’s a certain faster buzzing with a certain amount of force, but if you up that to say setting 3, then press harder into the workpiece, the resulting boost seems more than on the lower setting. I’m sure it’s an improvement, if only for when you don’t have a vice or whatever, to hold the workpiece/calliper, it’s safer than a wild rotary action on an angle grinder or drill maybe, and some weird dints and crevices are positively elusive without a direct-line hammer action. So, that’s my tip. Drawbacks are, as expected, the bristles do ‘bend over’ at the tip after a bit, but I suspect if I either wrap duck tape or maybe use a couple of tie-wraps or circlips/jubilee clips, to keep the bristle ‘bunched’ properly then it mightn’t let the bristles bend at the tip. I only just got a vice, after 50 years of working on cars I thought I better start making it easier. Getting the tools I always avoided buying. Sandblasting is obviously really good. Laser, is really, really good, but will get cheaper I am sure. My only issue is laser rust removal is awfully easy - you have to get set up to sand blast, your child or curious teenager isn’t going to readily mess with a sandblaster booth. Lasers are somewhat dangerous when they are that powerful, and it’s a bit like welding which now is also very cheap…I was put off not by the PPE I needed to buy, but by the need for a neat workshop. I’ve got naptha and all sorts in there! So until I have a decently-sorted garage, welding is another thing to steer clear of for me. Good vid, take care all.
I know most BMWs have this style and the service manual specifically states to clean the guide pins but so not lubricate. Due to the pins potentially being open to the elements, any lubricant could attract foreign contaminants. Sealed systems such as Kia and others are within the metal caliper bracket and need to be lubricated.
To all those saying, “this looks professional.”The final product does look great, and I’m sure will last. However the grease used to lubricate the caliper piston is for the outside parts such as the sliders or pad guides. The only lubricant that should be used to lubricator brake piston seals is brake fluid, or else you risk contamination of the brake fluid and seal failure.
I was rebuilding my read clipers and I struggled to put a new rubber boot back in place. The rubber boot end has a metal ring which I could not mound on the groove even with a force and you seem to mound it fairly easily 7:13 Does it need a lot of force?
@IDontTalkToCops if its an old car fine. If its a newer one and parts are easily available. Theres enough work there already. Get a core charge if you can. Olenty of fun doing that job. And not this unessacary bit.
@lucaslagun8283 i can buy an oem part for most vehicles upto 20 years back. I could see this on something vintage. Though often they do complete highend brake setups on most I've seen. I'll stand by its cheaper to buy than the time it took the person being recorded to do all that work.
Caliper paint is heat resistant to 900*F. It is also very chemical resistant. Would have been nice to know what black primer you used and the final coat. They do look tremendous and that lemon acid trick is da shizat.
zinc primer probably silicon-organic base (temp resistant). And final paint based on silicone polymers. I would use paint for the calipers to be sure of paint compatibility. Thank you!
the bore in use is protected by the brake fluid, which as long as you replace at the correct intervals wouldn't suffer any corrosion issues, and the sealing surface is the piston anyway so don't need to stress to much on the bore
Unless you used some VERY special paint, any DOT3 or DOT4 fluid drips from final assembly or bleeding will eat off that paint and expose bare metal. I wonder if powder coating would be able to withstand this...
Some folks don't like powder coating because it comes out a bit goopy-looking. The spray finish tends to retain details better. I've seen this on my motorcycle project.
This is (or should be at least) a lubricant that withstand braking fluid. It should be used on surfaces that have contact with DOT fluid. For example I use "ATE bremszylinder paste", but i do not know what is this what he uses in the video.
Having worked at a gm dealership until early 2000s....I can say that the factory never painted calipers from the factory... Unless it was a special package.... Which was NOT the majority
Might i suggest using the correct size spanner rather than us a poorly fitting adjustable wrench, they are very prone to rounding over the edges of nuts. ☹
The acid does trash threads. Try it by putting a bolt and a nut in vinegar and see how loose the connection gets. I have done this. If you were able to seal the threads well with some plastic fittings and maybe Teflon tape to seal them. It would work. The piston housing itself doesn’t really see the piston. They don’t come into contact with the walls of the housing. Still. I would seal the piston hole off while using the …..vinegar or citric acid. I would not want that bore to be ate down by the acid. The acid when washed off. Creates immediate flash rust. Yours were very clean. I don’t know how you achieved this. I have achieved this by washing the metal off and immediately putting them in oil. Giving it no time to rust. Then I have to clean it again with solvent. The zinc primer is not bad. It has anti rust capability. Is this worth the time? Not really. You can buy the parts for not too bad. However. You can buy a rebuild kit for $5 and never do any of this at all. Just keep them rusted. The factory doesn’t coat them on many cars. They just rust. Newer cars coat them. I have done all of this several times and am about to again. I might go through the trouble of de rusting. Only because I’m doing several calipers at once. The paint is just high temp caliper pain and it does have to be baked on. Powdercoating is better😊
This is the proper way to do this. Complete disassembly, thorough cleaning of the components, correct masking of contact surfaces, then high heat paint applied and cured. Agree with those who say to chase the threads to prevent galling upon reassembly, and possibly honing the piston bore if needed. Overall, very well done.
Earplugs are great for plugging bolt holes for paint.
Nice result. It'd be great if you explain the steps you go through and the materials used for restoring/rebuilding the calipers.
Wow...that is a professional job. What great work.

I think you can try use vinegar, just soak it for one or two night or more for bigger parts.

Great result! How long did it take for the lemon acid to remove the rust entirely? You also heated it, what was the temperature?
How did the BRAKE BLEED NIPPLE MOVE TO THE OPPOSITE SIDE?

Mine were severely pitted but still looked a whole lot better after cleaning and painting.Liked.
what chemicals do you use to boil the rust off?
It's citric acid
To remove the piston it's more easy/fast to use air compressor gun with any rubber for quick seal.
All threaded holes need to have bolts screwed into them before sandblasting and painting. Then, a thread tap must be run in to clear out the threads.😊
Just stick foam ear plugs in if there nice and snug, should be good.
Music made me turn off.
No one cares
It's called mute ✨

You can pump the piston out before removing the caliper from the car
@@olejakobsen2363 indeed, this is also true. just remove the brake pads and you push it out. Off the disk of course

Do you use lemon acid to clear rust ? Water and lemon acid is safe for this ?
How long did you cook with citric acid?
How did you dry it then?
6 hours to get the paint dry. 6 hours in the oven @200° ? °C or °F ?
Отличное видео! Тоже буду реставрировать) Сколько по времени ты в лимонке отстаивал? Кипятил?
great but no grease on the slide pins ?????

You need to lubricate the slider pins otherwise it’ll seize up pretty quickly.
Not on these styles...many manufacturers don't recommend lubricating these.
So when should we lubricate and when not? Can you explain please?
@@wcmauldin81what calipers are these for because it’s the first I’ve ever heard of it? They will get water ingress and rust.

You shouldn't use lubricant on this style caliper, as dirt will stick to is making the pins stick as they are partly open to the environment

Hi. Thanks for the video. Why You use a heat after painting? Can I use a bike pump to extend the cylinder?
yes. you can use bike pump. heat is because for making sure paint doesnt fade when install on car
@@MrOner07 You can also put it out when caliber is conneted in your car, take it out disk and only push brake pedal.
What type of paste did you use on the brake cylinder?
light grease lube type doesnt matter too much
Polyalkylene Glycol

The logo on the calipers reads “Ford”, of course many Ford and Mazda parts are interchangeable depending on the market you are in .
Good job 👍
"Like from the factory"
you kidding me?? that's thousand times better than factory.
You can use grease gun instead of air pressure, its safer and soaking calibers in winegar instead of citron acid, nice work anyway.
just make sure you fill it with brake fluid, grease will destroy the rubber.

Why does it fell like a fake to me - with that citric acid?

The zinc primer is not bad. It has anti rust capability.
Is this worth the time? Not really. You can buy the parts for not too bad. However. You can buy a rebuild kit for $5 and never do any of this at all. Just keep them rusted. The factory doesn’t coat them on many cars. They just rust. Newer cars coat them.
I have done all of this several times and am about to again. I might go through the trouble of de rusting. Only because I’m doing several calipers at once.
The paint is just high temp caliper pain and it does have to be baked on.
Powdercoating is better😊
