id check the fluid level, normally a pedal that mushy is a leak somewhere, im guessing a possible master cylidner leak.



to check if its the master cylinder, if you push it real fast and it sinks and doesnt stop much let it up and press down quick again, if its stronger now, feels like it built up pressure, you have an internal leak in the MC.



basically you shouldnt have to pump your brakes to build pressure with the car running.



sometimes thats tricky tho because altho it shouldnt happen with a bad booster sometimes it does, which is odd. But of course if your MC is leaking too long the leaking fluid will build up inside the brake booster and eat away the diaphragm....which would kil the booster. but with the booster kill your pedal would be harder to press. bah whatever, disregard this whole last paragraph, im being to technical i my head.
