Thanks for your help on the above, passed MOT yesterday with only a couple of advisories. One being the handbrake passes but could be tighter.
I know the handbrake can be tightened by removing the heat shield and tensioning the cable, but as the handbrake holds I'm guessing its on the limit before the piston pushes out a bit more to add more tension. Would this be correct?
Knowing the piston pushes out when the handbrake is pulled pulling the lever on the caliper, is it correct that the piston only moves when the lever has say 90% travel or does the piston push out with 1% travel from the lever?
