When l recently bought my E86 Coupe the handbrake was crap and would not hold the car. Last weekend l replaced the rear discs and noticed that the handbrake shoes were well out of adjustment so after a good clean up l adjusted the to where they should be and found the handbrake a lot better but still slightly lacking.. my question is can the cables be adjusted at the handbrake lever end like the Z3? If so how easy is this? Thanks in advance..
