What's wrong with my rear brake?
Posted May 02, 2003 - 10:07 AM
If I tip it over on the side stand and spin the rear wheel, then put the brake on, it will stop fine. But not when it has riding momentum behind it. I do hear a clicking noise in the caliper when the brake is used.
I Just started bleeding my brakes but I never have taken a caliper a part. Any thoughts on what may be the problem?

Can the pistons be pulled and cleaned while the caliper is still on the bike (with the wheel removed of course)? Or am I gonig to have to pull the whole thing off?

is the brake line ok ? and on my 98wr the exhaust had heated up the plastic master cylinder enough to cause the plastic to warp and the top wasnt sealing ! if you got wd40 or something slippery on the rotor, give the pads a clean too.

a.) add fluid to the reservoir.
b.) connect the bleeder tightly * and connect your waste contianer hoses to the bleeder ( * if not tight, it will draw in air).
c.) while bleeding, slowly apply the brake several times (4X).
d.) on the final application push down and hold the pedal.
e.) loosen the bleed screw and allow the pedal to travel to its limit.
f.) tighten the bleed screw when the pedal has reached its limit, then release the pedal.
g. repeat c through f until the pedal is good and tight (no air).
I suspect the pedal push during bleeding and/or the bleeding to the pedal limit was not performed. Up till this point you've described nothing that would indicate a frozen caliper. Good luck buddy.....

I did have to replace the reservoir this morning. It broke at the bolt on part on a crash over a year ago. I've had it zipped tied since then. It worked fine. But I bought a new one a while back and decided to put it on with the fluid flush. No way around getting air in there. I pumped for a full bottle. I pumped and I pumped, but the bubbles just kept coming man. They weren't stopping for nothing. It was like the Viet Cong advancing on Charlie Sheen's regiment in the last battle of Platoon. Oh, sorry. It got away from me.
Seriously though, are there times when you just have to keep pumping and pouring for a long time to get all the bubbles out?

Otherwise, how about a master cylinder rebuild kit. Easy to install, and boy, what a difference on my 97. I pais under 20 for the kit.
Auto Zone has the mightyvac for way cheap. Unser 25.00.
To be 100% honest with you, rebuild your mastercylinder.
