Honestly your guess is as good as mine. But I don't think the master cylinder is NOT bad you still have air in the system. Get a big bottle of brake fluid bleed all four sides until you run out of fluid or your brakes work properly. You should divide the bottle's content in four, then use each quantity in each side. You'll be removing air and contaminated fluid from the system. Get a small hose that fits on the bleeders and an appropriate container. I have a good feeling if you do this your brakes will work just fine. I don't know how you are bleeding the brakes. I'll let you know the proper way just in case. This is a two man job, with the wheel off, have someone start the car. Have them pump the brakes a few times to get pressure. 1With the brake pedal UP open the bleeder, 2then have your assistant press the brake pedal all the way down and leave it completely pressed down. 3Close the bleeder valve, once close and only with the valve closed have'm release the brake. Repeat as necessary, bake depressed, open valve first then press brake. DO NOT depress until valve completly closed. Close valve THEN depress. Good Luck!

I just went to Brake Masters this morning and had them replace the Master Cylinder since I was experiencing the pedal very spongy and going to the floor. When they replaced the Master Cylinder and they gave me back the car, the brakes were still spongy and going to the floor. I addressed this to them and they took another look at it, but when I took it for a second time, the brakes were extremely spongy. It was almost like they gave me back my car in worst condition to when I brought it in. Can you help?

sometimes if you leave the bleeder screw open it will gravity bleed the cylinder.Make sure master cyl is full and do one wheel at a time.I have seen this work, I have done it.
