Hi @bookwormdmc ,

Check if the brake booster is working OK.

Here’s how to do this

With the engine off, pump the brakes — about five or six times is sufficient. This depletes the stored vacuum.

Turn the engine on while pushing down lightly on the brake pedal. If your brake booster is working normally, the pedal will fall away a little, but then become firm.

If your brake booster is not working correctly, nothing will happen, or the brake pedal will push back against your foot once the engine starts. This could be a sign of a brake booster problem or an issue with the vacuum hose.

A faulty or loose vacuum hose could also affect the engine.
