Have you ever driven someone else’s car and applied their brakes for the first time – only to come to an unexpectedly sudden stop because you’re not used to the brake being so hard? That literally all it takes is about a feather’s worth of pressure to come to an immediate stop?
That simply means their brake pedal is hard. What causes hard brake pedals, you ask?
“The most obvious cause for a hard pedal is simply not enough vacuum. Any brake booster requires a minimum of 18” vacuum to operate efficiently. Anything less than that will contribute to the pedal being harder to push. If your vacuum is in the 16” to 18” range, a vacuum canister might help your situation”
If you have some mechanical knowledge of the braking system of your car, you can try the following home-based troubleshooting. Thanks to MPBrake.com for the info!
A) With the engine not running, press and depress the brake pedal several times to remove any vacuum from inside the booster.
B) On the last push of the brake pedal, hold moderate pressure on the brake pedal. Don’t push like you are panic stopping, simply hold pressure like you are sitting at a red light.
C) Start the engine and pay attention to what happens to the brake pedal.
D) If the pedal drops slightly, then the booster is working correctly.
E) If the pedal does not move at all, then there is a very good chance the booster is bad.
