Disc brake pads need a proper backing so they don't vibrate. Brake pedal pulsates when I apply the brakes. Disc brake rotors are out of round and need to be resurfaced. When stoped at a traffic light, brake pedal slowly goes to the floor. The master cylinder is bad and needs to be replaced.
Car pulls to one side while braking.
The front disc brake caliper, opposite of the pull is not working and will need to be rebuilt or replaced. When I apply the brakes, one rear wheel grabs. A rear wheel lock up is caused by fluid on the brake shoes. Check the rear wheels for a leaking wheel cylinder or axle seal. Thermostat stuck in closed position.
