Hello all, I have the following test: I have a 405 GRDT, Bj 88, meanwhile now 318000km. I had noticed this week that the brake pads are finished (at the grinding noise of the metal). When I was on the way home, I could suddenly kick the brake pedal down to the stop and the braking effect was more than miserable. When I had tried to do a full braking at a slow pace, I noticed that it only braked at the rear right and nothing else was possible. ehr. Now I had brand new discs with pads on it today, because they had to be changed anyway and thought ok, then it gets better. But now I still have the long pedal path. I can step up to the stop and if I have the brake fully kicked and then let the clutch come, he pulls away like if nothing was there. What can that be? Can it be that the piston has squeezed out of the brake caliper? Or rather maybe wheel brake cylinders? Who can give me here a Thanks and mfg Oly
