can anyone help? just had my new compbrakes fitted last week and as like before they still pull to the right, changed the brake block in the engine bay (under the battery) worked fine for a day now it started to pull again!!! sometimes evening lock that wheel up whats the problem ?????? cheers

 

If they are still on a diagonal system have you checked the opposite n/s rear caliper is working ?

 

you may have an air lock in the valve block, easy to do, difficult to get rid of in some cases

rebleed the system at the front but if you still have the issue and it's all pointing to a sticky valve block, i'm not sure where you would go to get it unstuck unless you find one from a working car
