The brake pedal feels mushy and goes way down to the floor. I hear a vacuum leak noise when I push the brake down. First time it was repaired they said it was a dirty brake systmen and replaced some brake fluid. We took it back because there was NO change after they worked on. Next they said it had a bad master cyclinder and they replaced that. After bleeding the system twice they said it now needs another part. The total cost of this lastest work is going to be around $800.00and we still don't have our car back yet and don't what else they are going to say it needs.
