Hi,

What you described sounds related to either the vacuum brake booster or the check valve. The booster provides assistance when braking (makes it easier to push the pedal). The booster is actuated by the engine vacuum. If there is a leak, the pedal will get hard to press.

Do me a favor. I attached diagnostics below that require no tools. Perform the tests and let me know the results.

Let me know if you have questions or if I can help.

Take care,

Joe
