Why is my hard brake pedal not working?
An obstruction in the hose could also be limiting vacuum contributing to the brake problem, so be sure to check this area thoroughly. Another quick check would be the location of the vacuum source within the engine and the fittings used to install the vacuum hose.
Why do I have no brakes on my car?
I’ve had customers come in and tell me they have no brakes because they have to push the brake pedal harder than normal to stop their car. They can stop the car but they practically have to stand on the brake pedal to get it to stop — it feels more like stepping on a rock than stepping on a brake pedal.
What’s the proper hose for a hard brake pedal?
The proper hose to ask for is 11/32” vacuum hose. If you are running a fuel hose, when the engine is running and pulling vacuum on the booster, there is a good chance that the hose is sucking shut. If it is sucking shut, there is no chance of a vacuum being pulled on the unit.
How can I test my power brake system?
Power brake systems may be tested for hydraulic leaks just as ordinary systems are tested. Test for the presence of assist vacuum by depressing the brake pedal and releasing it several times. If vacuum is present in the system, light application will produce less and less pedal travel. If there is no vacuum, air is leaking into the system.

Where does the brake pedal start on a car?
Place a drain pan under the right rear wheel. The general rule is to start at the brake farthest from the master cylinder (right rear), and then work your way closer, ending with the left front. Open the bleed valve about a half turn, and have your partner depress the brake pedal.
