What's Wrong With My Brakes?

Troubleshooting Brake Problems - Brake Pedal Too Firm
Brake Pedal Too Firm. If you step on the brake pedal and all of a sudden it feels like you're doing leg presses at the gym with a new personal trainer, your brake pedal may be too firm. This symptom points to a few potential problems, all of which need to be fixed as soon as possible.


  • Vacuum Problems: Your brakes are easier to press because of a brake booster that gives your foot the strength of 10 men. This booster uses vacuum to help you activate the brakes. If there is a vacuum leak somewhere in the system, it won't have enough negative pressure to do its job. Check the vacuum system for leaks. If you find none, your brake booster is probably bad and will need to be replaced. This can be tested by a shop if you want to be sure.
  • Brake Line Obstruction: It's possible for something to block brake fluid from reaching a portion of the system. This could be something in the line like a chunk of rust, or it could be a pinched brake line. Visually inspect the brake lines and replace damaged brake lines as needed.
