Brake Issue

Brakes are spongy and will go to the floor with a little pressure. Firms up if I pump the pedal with the car off. Bad master cyl?

check fluid. if you recently did a fluid change, then it has air in them.

Nope. It’s rock solid with the car off.

No fluid in the booster, no leaks at the calipers, and the fluid level is good...

I'm in the same boat. I've tried everything. I'm leaning more towards vacuum in my case though but still haven't sorted them out.

I'm about done with this thing. It's fun, but damn it's a pain in the ass

This doesn't tell you it you have a problem with your brakes . Your pedal should firm up when you don't have the engine running . If you pedal is going to the floor when the engine is running you may have air in the lines , bleed them or you could have a brake booster issue.


When you have the engine running and you pump the brakes does the pedal firm up ?
