Have a small problem with my handbrake and I have to adjust it roughly on the drums, since the screw on the lever is already completely turned in, it is written in the manual, which has to be rotated through the hole in the drum a adjuster until the disc can no longer be rotated and then back again 5 rests. In theory quite simply, but how does it work in practice, how can I find that the hole is in the correct position? Oh yes last September were v in a workshop the coverings changed, think they made a mistake when setting.
