Having problems with your 1996 Isuzu Trooper ?

Rr.ABS and the brake lights on

\015 Thank you guys for all the help you provide, I have a 96 trooper with Rr.ABS and the brake lights on. about 45 sec. after I turn on the engine, it comes on. I don?t even have to push the brake pedal or pull hand break. brake fluid is full. Some times "very rarely" front right wheel locks when I slam on the brakes and I can smell the hot brake pads from that corner, I changed even the caliper on that wheel but still didn't help. the front right wheel might not have any thing to do with the warning lights.\015 Posted / edited by AnonymousUser on : 16-10-2017

Answers :

CHECK TO MAKE SURE WITH CAR RUNNING VOLTAGE AT THE BATTERY SHOULD BE 13.5 VOLTS TO 14.5 VOLTS. USE A DIGITAL VOLT METER TO CHECK VOLTS AT BATTERY. WITH ENGINE OFF BATTERY VOLTAGE SHOULD BE 12.5 VOLTS. IF NOT ALTERNATOR NOT CHARGING BATTERY.THAT WILL MAKE ABS AND BRAKE LIGHTS COME ON AND A FAULTY BRAKE LIGHT SWITCH WILL ALSO CAUSE ABS AND BRAKE LIGHTS COME ON.IF ALL LOOKS GOOD.HAVE THE ABS BRAKES SCANNED.IN THIS CASE YOU ARE HAVING BRAKE FAILURE.BECAUSE WHEN BRAKE LIGHT COMES ON THATS WARNING BRAKE FAILURE BECAUSE THE BRAKE MASTER CYLINDER AND ABS UNIT IS TOGETHER AS ONE.NOT SAFE TO DRIVE.COULD LOSE BRAKE CONTROL AT ANY TIME TOW IT IN.
