Most of the car today has power brakes that help make the braking much easier cars are equipped with power brake that is vacuum-assisted when the power brake has a problem the driver has to step extra hard on the brake pedal to stop the car. Vacuum-assisted power brake unit uses vacuum from the engine to help in applying the brakes, it has a vacuum hose from the car engine into a round metal or plastic canister and can be found between the master cylinder and the engine compartment firewall.

To determine the cause of the problem observe the car engine, when the engine runs roughly the possible problem is that the vacuum hose is broken or there is a leak somewhere in the vacuum hose. However when the engine runs roughly only when the brake pedal is depressed while the car is park then the possible problem is that the canister is failing.

What to do?
