I always get pulled up for my hand brake on WOF. I know that they are not a good system and replacing them with shoe version is the way to go. But that costs money and a lot of time or a lot of money and not much time I don't have much of either.
I just put new rotor/pads on the failed side (drivers rear), adjusted piston to get rid of play adjusted cable as tight as I can before passenger side grabs.
WOF people still not happy. Now they failed me on my winch bar (another story basically they WOF guy is a prick.. I came out asking if "was that my diff making that sound" the sound of an exploding differential.. when he tried having one side of the car on the roller machine testing one wheel which won't work as I have an LOKKA... I lost my cool when he started talking about permanent locked diff is illegal) Lucky for me everything still works, pretty strong things.
Anyway.. my hand brake is only at 67% Drivers side and other side is 120% its a big improvement from 6% / 120%.
I'm wondering what else can I adjust on the bad side to improve it, can't see any other adjustments.
