So about two weeks ago i changed my master cylinder because my pedal was going down at lights and under sudden stops on the highway. The problem is back actually now my brake are having a weezing noise when i stop, additionally in order to feel the brake pedal harder i actually have to press the brake pedal let it go and once again press on it. What do guys reccomend, maybe air in the lines? bad master cylinder... what... i am scared to drive the car the way it is but i have too until tuesday when its my next day off what do you guys think?

Be sure to flush the system not just bleed it, hmm that's weird if it's still acting up even after the MC. There could be a problem with the booster, try taking a look at that... maybe test the pressure or check for leaks.1998 Camaro Z28 M6 Hard Top - Sebring Silver - All Original, Bone stock

Check for a vacc leak.. Bleed, lube caliper pins, and try again.. Also check for a cracked/pinched brake line.. I've seen folks accidently crush/crack under belly lines with a jack b4.. Aswell (something to check) as brake fluid leaks that did not drip but leaked under the pressure of braking look for "wet" spots around hard/soft lines.... Especially anywhere it's attached to the unibody..

Guys thanks for te feedback!
It was actually the calipers ! One was leaking through the pistons so I had them replaced ! New pads and bleed the lines ! Now it's better than new
