Still failing on the handbrake!!
Discussion
Took the car back to the garage this morning. The guy put the car on the rollers to test the handbrake and the O/S is still failing.
I have removed that handbrake caliper againjust to check that it was still freed up. No problem there, everything appears to be working OK.
The thing I did notice is that the handbrake pads are rubbed in one area only. This indicates that there is not full contact between the pad and disc. The problem might be as simple as that.
Is there a knack to adjusting the handbrake pads to help ensure that they are fully in contact. The Steve Heath bible says to tighten the adjuster until the pads grip the disc and then back off until the split pin will go through the slot in the head of the adjuster screw. Well I thought I'd done that. I just wondered whether anyone had come across any way of checking the adjustment or other tricks.

Out of curiosity, which flavour of Wedge have you got, more specifically, which diff? If it's a Powerlock LSD it shouldn't be tested on the rollers in the first place!Adi
When I had mine the HB was always a ball ache. Careful adjustment immediately prior to getting it tested seem to be the order of the day, almost over tightening it, then just accept it was crap until the next year.
I admit that I couldn't be arsed to type it all out myself so copied and pasted this from a bookmarked thread in the Griff forum.
An LSD effectively 'locks' the rear wheels into rotating together.. (Well with some slip). In simple terms, imagined it is locked in the middle, rotate the wheels then apply a force to one wheel only whilst stopping the other rotating any faster.. It can wear the LSD plates or even break it.
If you jack up the rear end there will be two tags on the diff, one giving the ratio IIRC and the other stating if it is a Powerlok or Salisbury.
Also with both wheels in the air you shouldn't be able to turn one whilst holding the other. Or, pull a good wheels pin in a straight line, if it's an LSD you should have a lovely 11 up the road

I think they still do the handbrake on the rollers though?
My handbrake tips (I have had 20+ MOT's on wedges):
My handbrake tips (I have had 20+ MOT's on wedges):
- get a few more percent by cleaning pads and discs with trichloroethane (or failing that Meths)
- bed pads in by going for a drive and stop the car (when safe) from about 20mph on the handbrake - repeat this a few times. Then adjust.
- adjust like Steve says but before backing off pull the handbrake up hard and let go - then you might dial another half turn on the caliper adjuster.
- never bother adjusting the cable adjuster.
I must admit, I had considered point 2! Now that the exhaust repair has fully dried I will take the car out and do that. Irrespective of how accurate the final adjustment of the pads is it will help to wear the pads to the same angle as the discs.
What do you mean by the last point Adam?
