Hey, with the car (Spriter, BJ 2003, Sprintshift) both rear wheels are blocking. The front wheels are spinning without any problems. When I start and give a lot of gas, the car can be moved. However, only with approximately full throttle, connected with the following draughts. When the car moves noises come from the rear wheels (a short squeaking, sounds like the brake lining constantly and strongly presses on the brake disc. Had the car awarded, it probably drove to the yard without complaints and the problem occurred only on the last meters. I have already been a little busy with it. The rope of the hand brake is loose and all the components seem to be able to move freely. Also, the classic locking of the brake saddles I can actually rule out, the problem has occurred quite suddenly and there was no longer (even a short) standing time (had I checked before the braking test). It seems like on the brake system is a lot of pressure. The resistance from the brake pedal is very high and it is just a little bit down. But this does not change the brake force quite a bit. But the brake wheel has changed.
