Thanks for the excellent video John. Putting a Tokico on the Sportster and decided to rebuild before I installed . This will give me a leg up in my quest for better braking.
Hi guys, very nice presentation, well presented, well documented, very nice explicit, very nice all the way around, must kind of you for everything, "just a point of view," it is a must to check the piston seals position not been mention in your presentation, respectfully.
Unless they are frequently getting wet and sitting for long periods, you shouldn't have to do it often. Depends on regular care and maintenance. If you're replacing them, you can grab them with pliers, it is a little tough though.
Tim V there are tools specifically for pulling out pistons. I have one that is like a pair of pliers but they grip the pistons on the inside to prevent damaging the sealing surface. There are also other types available if you do a quick search.
That sludge in the caliper is because not changing the brake fluis on time right? Because old brake fluid attracts moisture. And then you get nasty calipers. Correct me if im wrong.
I noticed you didn't use copper grease on any of your rebuild, this seams a big bone of contention on UA-cam and forums. I don't use it myself on brakes (sometimes on the slider pin) Why don't you use it?
I don't think this is a good example of how to do it and carries significant risk of injury that's easily avoided. Use the appropriate tool, it's called a motorcycle caliper piston puller/remover and works by a collar being expanded into the hollow of the piston, then you just pull to extract it out. Many use an air compressor, but I would never class it as a good way to do it, I have also done it and after having a piston take a chunk out of my concrete realised it's just dangerous and a better way has to exist, sure enough I found the tool, and if that can't do it, pump the pistons out under hydraulic pressure from the master cylinder, hydraulic pressure isn't like air that can be compressed, so when the pistons pop out the force is immediately lost and the piston doesn't fly out like it does with air as the air continues to expand. Also, leave the two halves together, and simply fit a long strip of metal or a long spanner between the calipers, the same like the disc would fit, then when you pump out or using a compressor then the piston contacts the metal and will bring all the pistons out the same amount equally and the metal stops the ability for them to fly out. I know your comment is old, but hopefully this is some help for you or others in the future.
@@aarghitsjesta thank you!!!. definitely ordering now, cuz that part in the video with the pistons firing like rockets using the air compressor, made me nervous to do myself. lol
I really love your videos John. I would like to make a suggestion for future video - how to replace brake fluid on HONDA CBR600RR(PC40) or CBRR1000RR with ABS. I saw that procedure in service manual and I found it rather difficult and would like to see how a professional deals with it :) Thank you and keep your videos coming :)
canned air works too, or pump em out as far as you can before draining the fluid, sometimes with a bit of presistance you can pull the last bit out if you open the bleed nipple when you try to pull em out
Finding this thing and having the exact bike is freaking great, thank you sir!
Thanks for the excellent video John.

Would love to see a video for the brembo caliper rebuild. Are those more difficult?
Hey, Could you please make a rear caliper rebuild video? Your videos have help me HEAPS.

Very good video ...keep the good work
Tidy work, thanks
Awesome videos. How do you recommend getting the old pistons out if one doesn't have a compressor? Also how often do the calipers need rebuild?

Ottimo video spietato molto bene.

If it sits too long, you can get corrosion.

Any recommendations on how to get the piston out without an air compressor

just use the brake, the fluid will push it out(this requires the brake line not be disconnected)

We will add it to the list!
Wow this poor GSXR was neglected. Dont let this happen to your motorcycle people!
How would you get the pistons out without an air line?
Not really, you can use a grease gun, but that would be pretty messy.
You can pump them out with no pads in before you remove them from the bike
canned air works too, or pump em out as far as you can before draining the fluid, sometimes with a bit of presistance you can pull the last bit out if you open the bleed nipple when you try to pull em out

I feel so dumb....never knew it was this easy
Now ya know!
Why not just use a MityVac to drain the brain system rather than letting brake fluid drip everywhere?
Just showing different ways to do it.
