Title: Fixing the slipping handbrake
Post by r33per on Sep 17^th, 2007, 5:49pm

At my last MOT, the garage said that they had to make an adjustment to the handbrake to stop it slipping. They said that if it gets bad again, then I would require new rear calipers.

Well, it is happening again. So, I wanted just to check that:

a. I actually do need to replace the calipers
b. If so, what are the part numbers so that I can purchase them myself?
c. Should I be thinking about anything else e.g. replacing the pads as well?

Thanks.

Stu

take rear wheels off and look at the handbrake quadrants get some one to pull hand brake on and off if the quadrants dont move fully back and forth change calippers,if dics and pads are worn change them aswell

The usual problem with the HB is the spindle arms which go into the caliper seizing up. These are on top of the rear calipers, have the cable hooked on to them, have a strong spring to return them and should move freely as you apply and release the handbrake.

Usually they stick in the part on position, which prevent the handbrake from releasing fully as well as preventing self adjusting. It also makes it not as good as it could be.

Depending upon how seized they are, you can sometimes get away with spraying WD40 around the operating arms. If they are tight they need to be taken out, cleaned up and greased to refit them.

Turn the arm with an open ended spanner to unhook the cable end nipple, unhook the spring the arm should then lift out to enable it to be cleaned up. A small O ring in the socket is supposed to prevent moisture from getting in - it might be worth replacing these with new.
