Just been trying to set up '6566' parking brake, as one side was sticking. It has Wilwood brakes all round on the hydraulic circuit and retains the Girling brakes for the parking brake function. I found the issue with the sticking being the small plastic part that supports the return spring was cracked and fell apart when I released the parking brake cable that side. It also damaged the rubber seal.
That is no longer an issue, as I have found a place here in the UK that specialises in fully refurbishing these (and other old vintage/classic) callipers which are also used on the Peugeot 504 etc... they arrive back next week. I have now looked at the handbrake cable itself and found the left side has come in contact with the exhaust at some point (the cable was replaced 3 years ago) and so I have removed it.
The questions I have, is why is there a 100mm difference in length of the the left/right cable and if this is correct, which side should have the longer cable (is it to do with the equaliser arm/wheel)? Also what should the lengths really be as I know some people have shortened them for their particular cars? I intend to contact a well known cable supplier here who will add additional protection on both sides to hopefully prevent the issue happening again (I note a few other owners here have had similar issues...). They can also alter the lengths no problem.
As usual , I look forward to your thoughts.
