My handbrake managed 18% efficient at the MOT on Monday, the limit is 16%. I've had both drums off and the shoes are in good nick. I can't believe the complexity of rods and springs and levers involved to give such a poor performance. The tester must have nearly pulled the handbrake lever out of the floor to get a pass as the self adjusters had done just that. After the test the RH drum was binding. backed off the little ratchet wheel all is free again. Question is, is there any way to improve the performance of the handbrake? The design seems to only allow the brake to operate on one shoe and the other end of that shoe is up against a slave cylinder with no pressure in it. (unless you have your foot on the brake)
