brake pedal goes to the floor The last time I drove the car the brakes worked as they normally do. Since then I have installed a 90mm LSX intake, TB and XER 230/236 .595/.601 110 LSA 110icl cam. Today is this first time I drove it since the new mods and the brake pedal goes all the way to the floor to stop. I mean it’s very bad as in it lines up with the clutch pedal when I’m at a light and both are pushed in. There is almost no feeling in the brake pedal when I push it and when it gets to the floor I have to push very hard to stop. I checked the reservoir and it is full. I also checked for leaks under the car and there were none. Is the master cylinder going bad or is it bad? What could be causing this problem if it’s not the MC? If it is the MC is a Cardone 102865 MC from Advance Auto ok? Thanks in advance for any help.

A vacuum leak will not cause the pedal to go to the floor. Your brakes at least need to be bled. The condition you describe is dangerous. Please do not drive your car until this problem is corrected.

Well I looked at the car again. No vacuum leak. I pulled on the hose to the brake booster and it made the swish sound. So I got in the car and with it off and when I pushed on the pedal it felt a little stiff but with about 2 more pumps I heard a gushing sound. Went to the front and my line lock is hosed. It was coming out of the side of the solenoid. I'll bleed the brakes and start the car tomorrow to see if they work now that I took the line lock off. It was a SLP unit for those that want to know.
