1995 Cavalier ABS problem

Yesterday I was coming to a stop sign and when I pressed the brakes I felt a vibration in my brake pedal, the car made a clunking type sound and my brake pedal went to the floor. Today its to the floor everytime I go to break and sometimes I almost lock the brakes trying to get the car to stop.

Any ideas on where I should start looking for the problem?

1995 Crap alier....I have one too, and I have the same problem...the ABS light NEVER goes off... and if it is off.... the break peddal is to the floor..... My suggestion is to bring it to the wreckers!!! I am seriously thinking about doing the same... First the ABS.... breaks, head gasket, rear struts, 2 new alternators, 2 new starters, 3 new coil packs, 2 sets of wires and plugs, and I have only had the car for 3 years... WHAT NEXT????

This is about the age you will start to get broken brake lines... check your master cyl. to see if you have fluid if not you have a bad line someplace...

Sounds like you better put new rotors and pads on. These cars have a horrible excuse for brakes......
