Hello dear community, I have the problem only after exchange, that my brake (belay & disc new) pulls when braking to the left. It occurs once and then not again. Sometimes it brakes as if it were throwing an anchor and sometimes you have to step in a bit harder. I changed the carrier (right side) for the pads also yesterday, because the floaters had quite a lot of play. I would have thought that the surface has bent despite brake paste. But that also does not seem to have been, d a that is still there. Brake system was also vented. There is no game in the crossbar bushings available. In my oil cooler action in April 2012 I saw porous connections on the vacuum system. And in a thread here I read that it could also be because of it.www.motor-talk.de/…/…effort-little-brakepower-t3346746.html?… And the reading” Now I help myself” does not help me so much Would it make sense to exchange the HBZ?, or if necessary di e vacuum hoses?
