Question:

Jeep ABS Lights/ brakes?

about 2 weeks ago my abs came on. and when i would drive it it wouldnt come on until i had to either stop short or would hit a bump (pothole). my brakes have also gotten soft and not as easy to stop as they used to be. they are brandnew brakes about a month old. the disks look like they have rust on them already, is that normal?my dads a mechanic and drove it and couldnt get the light to turn on, and the brakes were fine. were gonna take the wheels off and check, but any ideas?? thanks!!

Answer:

From the factory service manual. ANTI-LOCK BRAKE SYSTEM LAMP The Anti-Lock Brake System (ABS) lamp gives an indication when the ABS system is faulty or inoperative. The lamp is hard-wired in the instrument cluster, and is completely controlled by the Controller Anti-lock Brake (CAB). The ABS lamp receives battery voltage through the instrument cluster fused ignition switch output feed circuit, and is grounded by the CAB. The lamp is turned on by the CAB for about two seconds when the ignition switch is turned to the On position as a bulb test. After the bulb test, the CAB turns the lamp on or off based upon the results of the ABS system self-tests. The CAB continually monitors the ABS circuits and sensors to decide whether the system is in good operating condition. If the CAB turns the lamp on after the bulb test, it indicates that the CAB has detected a system malfunction and/or that the ABS system has become inoperative. If the brakes are soft they may not be bedded in fully yet. You may even have air in the system and the brake fluid may need bleeding. Rust on the brake discs depends on how often the vehicle is driven. If it's just sitting there in damp weather you will get rust pretty quickly.

New brake pads will make a pedal feel a bit softer or less firm because of the thicker pad material and it takes a bit of braking to set the pads. The ABS comes on? Do you mean the light or the ABS activates ? You may have an intermittent open circuit on one of the wheel speed sensors. Get the ABS system scanned so you know what's up.

Go with what the dealer recommends. TPC or tire performance criteria is important, not only for fuel economy but for braking, handling and prolonging the life of suspension components.
