Do you automatically bleed the brake booster as apart of bleeding each wheel brake cylinder? Or is there a different, extra step/process to bleed the brake booster (and if so what is the process)? FYI: I pumped each wheel cylinder approximately 30-times for each, as apart of the bleeding process, and it is significantly better than before; however the brakes still feel best/firmest on the second pump of the brake pedal. Wondering if it might be the brake booster or???
