alright my break pedal is really squishy right now. at first i thought was the fluid, it looked liek coke, so i put new fluid in and bled my brakes, but its still squishy. i noticed it gets EXTRA squishy and doesnt brake as well when going down hills. i also noticed what sounds like a big vacuum leak coming from under my hood. so i pop my hood and there are no lines unconnected, and the sound sounds like its coming from my master cylinder =\..any ideas on what i could do? also when i drive sometimes i hear my rotor rubbing on my pads, how do i get rid of that, its annoying as fawk. i can hear it loud when i drive by other cars.

 

Sounds like you need a new master cylinder, mine made the same vacuum noise when it was shot (and puking fluid everywhere.)

The rubbing can be caused by a stuck caliper, any of yours stuck?

 

did u try getting the air out of the lines..need two ppl...one to pump up the pedal and hold it whilethe other opens the calipar and closes when the pedal to the floor...i would try that first see if it gets any better...also it could be a calipar...i think there is a rubber piece that the fluid could be shooting right thru it..if its not that then i would try to replace the master cylinder.

 

make sure you bled the brakes correctly eliminating any air in the lines...a good device i use is a mity vac brake bleed system which only needs one person to use

 

i agree on using a brake bleed system where you can attach a hose to the bleeder bolt and suck down brake fluid. that way, you can see if air bubbles are still coming out of the hose.

btw, its spelled brakes ... sorry, but "breaks" is a personal pet peeve
