Why is it so hard to apply brake pedal?


_______power brake booster, check vacuum to booster and the check valve for brake booster. primary symtom is high hard pedal that requires greater then normal pedal pressure to stop car. testing booster= pump brakes several times with engine off to deplete stored vacuum. turn on engine with pushing slightly on brake pedal. you should be able to feel the pedal fade away a bit, and then become firm. But not hard. if you feel nothing at the pedal when engine starts. Brake booster is not working. Good-day! make sure vacuum is going to booster with engine running. it may just be a bad vacuum line or check valve.

1993 buick lesabre changed the front rotars and pads and now the cars brake pedal is so hard to push down to get car to stop. Mechanic has checked both the front and back brakes and they are fine. T


I would jack up a front wheel and see if pushing on the pedal with the engine running will stop the wheel from turning.
You need to know if the pressure is reaching the wheels, or if the pads and rotors are too slick to stop the car.
Usually if the pedal is hard, the booster is not working or the brakes are glazed.
Can you stop the car with the parking brake ? That only uses the rear brakes.
You may need a second opinion from a different shop.

Slow drag starts, stalling and surging when at a stop


you could have a brake booster issue. you can do a simple test on another car by leaving the engine off and press the brake repeatedly 3 or four times will use up the vacuum in the brake booster. Once you have done this does it feel like the brake pedal in your van?
