Having problems with your 2004 Nissan Sentra ?
Hard brake pedal. changed the mater cylinder. now all four brakes get stuck. any advise?
So is the pedal still hard? a bad brake booster can cause a hard pedal. Loosen the master cylinder about 1/4" from the booster if the wheels free up, then replace it.
