Day! I replaced the wheels and pads in the front and a few days later in the back. So wheel brake cylinders, cheeks and drums. As the parts for the rear came later I drove about 200km with the new front brakes and everything was ok. Now I renewed everything in the back and new brake fluidity is also inside. The car never braked as nice as now in my possession, however, the pedal vibrates when I brake at a higher speed. At 50 – 60km/h it feels normal. For example, on the AB of 120 I feel the vibrations in the pedal. Whether coming from the front or from the rear I can’t locate from the feeling, but since it only came with the new drum brakes I assume that the error can be found there. What do you think about it? Should I put the cheeks even further back or what? EDIT: It’s the drums: When I step on the park brake also vibrates. In addition, there are speed vibrations due to imbalance from the rear at high highway. are by the way AC Delco drums. Made in China.
