rear brakes seizing honda vfr

I just got my brake pads replaced, they were so worn the piston were had been sheared. The mechanic repaired them and i got new brake pads. Now when i ride and use them thoroughly they seize and will start to smoke.When they cool off they become loose again and work.

what is happening here?

 

Replied in the other thread too:

I would first try to bleed any air that is trapped in the system. Being that you had piston problems I would almost bet that your caliper is shot. You may also have a bad master cylinder that is the start of all the problems to begin with. What was replaced to fix it?

 

The mechanic replaced the brake pads.Now it is freezing after it warms up and i sue the rear brakes. After they cool down they work again. Something is jamming.

I am not 100% if i have to get new parts or do some re work.

 

When the caliper seals go bad they cause the pistons to stick. The piston stick the brake pad to the disc causing it to heat up. The heat causes the piston to stick even more. Then it cools off and releases. Probably time for a brake rebuild.

 

At least I don't have to get a new one

 

I would make sure there was no air in the system first. If no air is able to be bleed out then take apart the rear caliper and have a look at the seals, pistons and bores as mentioned. Good luck

 

Sounds like u need new brake piston SEALS and/or cleaning of master cylinder.

Brake reservoir should not be 100% full; you need some air space above fluid.

NO VFR brake job is done right unless the slider pins are cleaned and re-greased at the same time..,..

 

Absolutely right squirrel - you need to tear that caliper apart and renew everything.

 

I've usually found that sticky caliper pistons are worse when cold.

I vote for the problem being in your master cylinder. The small hole that allows for brake fluid expansion as it gets hot is probably clogged. When I've seen this happen, once you use your brakes and the fluid gets hot it locks up your brakes so tight that you're walkin'...then when the fluid cools, it's OK.
