Why is my brake pedal stiff and car wont start?
Your car has power brakes.
The power assist relies on engine vacuum.
Once all vacuum is gone, if the engine is off, the brake pedal will be hard to press because the power assist (via the vacuum) is not present.
Once the engine is running again, your brakes will be fine..
What happens if I change the brake pads but not the rotors?
As long as the rotors are still above minimum thickness you will still have the required braking performance. If they are not, you won’t and should replace them, not cut them, as cutting will make them thinner, degrading performance.
What does it mean when your brake pedal is hard to push?
Bad brake booster: The most common culprit of a hard brake pedal is the brake booster. A bad brake booster will be unable to provide vacuum assist, meaning that you will be attempting to depress the brake pedal with no assistance.
What does it mean if I have to pump my brakes to stop?
Air in the Lines: The number one most common cause for having to pump your brakes to get them to work is air in the lines. … Low Brake Fluid: If your brake fluid is low (and it’s not due to brake pad wear), then the system will be unable to create enough pressure for normal operation and you may have to pump the pedal.

How do I depress my brake pedal?
It means push the brake pedal down with your foot, preferably your right foot! This action slows the vehicle’s speed (if you’re moving) and if you keep pushing down steadily and holding, the vehicle will eventually stop.
What happens if you put new brake pads on bad rotors?
If new brake pads are put onto a vehicle with damaged rotors, the pad will not properly contact the rotor surface which will reduce the vehicle’s stopping ability. Deep grooves that have developed in a worn rotor will act as a hole-puncher or shredder and damage the pad material as it is pressed against the rotor.
Can I just replace brake pads and not rotors?
A: Unless the rotors are worn beyond the mandatory discard thickness, we prefer to replace the pads only. Not only does this obviously save money, but time. New pads must be burnished into new rotors before the best braking performance is achieved.
What happens if you don’t change brakes?
If you let your brakes go and never tend to them, the pads could wear out, the rotors could go bad, and a number of other things can break down. These things operate together as a team in order to slow your vehicle. When one or more item is no longer working, your brakes can fail.
