Rebuilding front calipers

[chrdog]

after cleaning my caliper pots twice now, im still getting drag on my rotors and im guessin they are gonna get hot and warp the rotor (oops too late!). i tried to clean all the gunk off the pots with brake cleaner, but some of them are still dragging and not moving very freely.

how do you go about rebuilding them?

You will always keep drag on the rotors from the brake pads, no doubt about that. But they shouldn't be doing that constantly.

I cleaned my calipers this spring and was advised by a mechanic to use lithium grease (not sure if you guys know that stuff) on the pots before putting them back. Didn't have any problems. Did you use any grease when refitting? Did you put the right pot back in the hole where it came from? That's also important.

Have you checked the other parts of the caliper if they were fitted back the right way?

take pads out.stick something there that is 1/4 inch thick.pump brake so pistons come out,clean.

Hmmm, I've never even thought of cleaning/rebuiding my calipers, maybe that would help out with the inconsistency of the braking?

[SUCATI]

Lithium grease? In a brake system? I think not. You're supposed to use brake fluid when reassembling brake calipers and master cylinders. That includes the pistons and their seals!

my problem is getting the pots out. i cant pull em out all the way, once one comes out the rest dont have pressure to push them out. even when i push em out one at a time bysticking something between the pots that are already extended, i cant seem to pull em out.

Well, better that it happens on your brakes and not on a date:lol:

Have you used compressed air to push them out? That will definitely do the trick. Worked for me as well. Is also mentioned in the SV workshop manual, I looked it up.

This what the manual says:

Place a rag over the pistons to prevent them from popping out
and then force out the pistons using compressed air.

CAUTION
Do not use high pressure air to prevent piston damage.

Like how much pressure?

Low as in less than 100psi ?

or

Low as in less than 15psi?

[Knaapie]

Doesn't say in the manual. I worked with 145 psi, but that's a little bit too much. :D I guess 70-80 psi will also do the trick.

That's good cause my compressor only goes to 135.
