Drivers who are experiencing a stiff brake pedal have good reason to look over the entire brake system carefully. We created this 4-part series to help pin-down and even potentially eliminate some issues that could make your brake pedal feel like you are standing on a brick.
If your hard brake cause can’t be identified in the most obvious places we previously wrote about:
- Part 1 - vacuum pressure in the booster
- Part 2 - valving - especially pressure differential valve
- Part 3 - your pedal ratio
...then something else within your brake system must be the cause.
If it's not related to the “top 3 reasons” behind a hard brake pedal, there are several additional possible problem spots for you to examine and troubleshoot. A thorough inspection of the whole system should help you identify any such underlying issue.
