Brake issues

[Chucky]

I have a 97 v6 camaro, almost completely stock except new exhaust, and my brakes have always been a little weak. Recently my brakes have been really bad when it rains and I would have to pump the brake pedal a few times before they would grab and I could stop. Thats not the issue though, last night I drove my car and it was just like normal then got back in it and left and the first time I hit the brake pedal everything locked up after barely pressing the pedal, and it kept doing that. I just took it to a brake place and they said it wasnt the brakes, does anyone else know what that would be? I checked the fluid and its fine. Also anyone know how much it would cost? Basically how I have to stop now is just downshifting because if I press the brakes at all they lock up completely.

Re: Brake issues

could be:
Faulty Master Cylinder, air in the lines, faulty abs unit, bad sensor(s), etc.
Any trouble codes?

Re: Brake issues

I had this problem and it ends up I had a leaking brake line. I would be driving and press the brakes and they would all lock up and the car's ABS would be going crazy. Check your brake lines, bleed screws, pistons, etc.
