Having been used to the handbrake in a more modern car I found the one in the ZT very poor in comparison. It would appear that the handbrake in the ZTs are generally susceptable to stretching if not adjusted correctly which reduces its efficiency and so this could be the case with mine.
I bought the cables from Rimmer (about £130!) and the compensater from eBay (£12.50). There are 2 types of (BMW Mini) compensater – seems that either will do the job but the one shown seems to be the preferred. I will be booking the car into my local garage for fitting and adjusting correctly …….. making them aware to be careful when removing the rear discs as I’ve seen new replacements cost nearly £500!!
