Brake Issue ! Rear Brakes Keep Locking On Ceffy

[bbe]

Last week my rear brakes were getting tighter and tighter till completely stopped. they was smokin

i pulled over had no tools with me so just tried unplugging abs, the car rolled again. MAde it home.

Now they are doing it again with abs unplugged so every klm you must pull over and relieve line pressure and they unlock and you can drive short distance again.

I have flushed the entire brake system and bled with new fluids. removed rear calipers and degreased an cleaned to make sure they wernt sticky but still the same problem.

Anyone have any ideas or explanation for this..

Any help muchly appreciated..

Cheers Beej

What do you mean by relieve line pressure? as in bleed, or just leave it alone for a while?

Sounds like you've got air getting into the lines somwhere maybe?

both sides? or just one?

both rears

and ye i just bleed fluid out to release the calipers

no air in lines that would stop them locking.

had this problem on my silvia 2 yrs ago i sold it lol

If it's not the brake calipers locking up (they aren't seized) then it's probably your brake master?

ye i changed the calipers since it happened exactly the same..

im startin to think master too ?
