I just bought a 99 Pontiac Grand Am 3.4 V6. My husband changed my brakes and when I was driving the ABS and Trac off Light came on, and stays on only when I am driving. We have tried to rebleed the brakes and checked to see if the wires are worn or broke, I also have hardly any brake pressure. This is the newest car I have owned I need help to fix this problem I do not want to have to take this is. Any and all advice would be helpful this is our ONLY vehical and we have a 2 year old.

I couldnt figure out why it used so much gas my dad said it he thought the caliapers were rubbing so we changed the calipers and the brakes since then the ABS and Trac Off lights come about 3 miles down the road. My dad took my back passager tire off and found that the ebrake hadd been pulled on one time (hence the pulling and poor gas mileage) but now that is freed. And still the lights are on. I'm regreting my car discession.

When you got the car di the lights come on, or only since the repairs. Also did you replace rotors and calipers or calipers and brake pads? Please bear with the questions I am trying to narrow our search and determine if we have a absfailure or possibly something else. Billymac

It sounds like the pads or the calipers are installed wrong. May sound crazy but thisis ver easy to do sometime when they are installed the pad guides will not align proper maybe a rattle clip on the bottom of the caliper when it should be on the top. I would take it back apart look at everything very careful. If iis all ok then air in the system will most likely be the problem.

A: There is a funny thing about Anti-lock Braking Systems that many people do not realize. The system doesn't know any thing about brakes. That's right the ABS system doesn't know anything about brake pads, shoes, calipers, rotors, brake drums, etc. In fact, I could remove your brake pads, brake caliper, even brake rotors and drums on some vehicles block the brake line so the fluid doesn't spill all out and your vehicle's ABS system wouldn't even know they were missing. Computers assume, yes they take for granted that the core components of the braking system are in good working order. If you have an ABS light on the first item that should be checked is the brake fluid level. Many ABS systems do tie a fluid level sensor warning light in the ABS warning light. But let's not assume and be sure the brake fluid is at the correct level. You now know that you have good brakes and that the ABS system doesn't know the difference. The next step would be to have a code check performed on the ABS computer. With the warning light being on there will be a code. That code will direct you in which part of the ABS system needs diagnosis. It is also likely that your traction control warning light will go out once the ABS problem is corrected. The 2 systems rely on some of the same sensors to operate correctly.

If you are sure there is no pro with the instalation of your parts then you can get auto parts store to scan system and pinpoint where the prob is. Let me know if this helps
