Your ABS light is on because the system detected a failure in the brake system. Sounds like either your master cylinder is bad or one of your brake lines has ruptured. Usually a master cylinder seal will degrade over time, not insantly. In a dual master cylinder configuration like all newer vehicles, you should still have some braking, even if a front or rear line ruptures. 1st step, check your fluid level.

SOURCE: ABS light on

Sounds like a bad ABS sensor. Which unfortunately is usually built into the HUB assembly and the whole thing needs replacing. Take is to a garage that has an ABS diagnostic tool and they can tell you which wheel is throwing the code and then go from there

SOURCE: abs brake warning light comes on and rear brakes remain stuck on

I would bypass abs contraption with new line.(87 dually) abs located under drivers side cab looks very susceptible and is known to fail.I would trust my foot before that old thing.Im rippin it out of my truck & replacing it with new line all the way back.Old lines rusted pretty bad.Better safe than sorry.unplug light bulb or just leave it in .Jersey cant say anything if its 94 or older at inspection.that goes for all the lights.For me,older is better.I dont know what setup you have or if you sold it, you could try replacing it for about 160 at advanced.I hope its not the computer screwin up,thats probably a dealer item.Try unpluging hydraulic unit for shits & giggles.Go over rear brakes again before you start cutting.

My Suburban had the same issue. Replacing the ABS control module did the trick, second one, the first was replaced under warranty.  I used these guys http://modulemaster.com/en/index.php with success.  It was very simple to replace, four screws.  Hope this helps.

On my 91 cougar it sat for about 2 months due to a power steering problem I fixed that problem now my abs and brake lights stay on is it possible if I bleed all four brakes they might shut off?


"Is it possible if I bleed all four brakes they might shut off?"

If you bleed the brakes all you will do is remove any air in the brake lines and replace the brake fluid with new fluid. Do this in any event if the brake fluid is 2 yrs old or more.

This will have no affect on the ABS warning light and when the light is displayed the ABS has turned off because there is a problem with the ABS. You will not get it back on until the cause is determined and fixed which may be just a failed wheel speed sensor.

The brake warning has probably been triggered by the same failure that has caused the ABS warning light (since they came on together and bleeding the brakes should make no difference).

If the car sat for 2 months, no doubt the battery went flat. You have not mentioned anything about the battery but if your battery is in poor shape this can trigger warning lights in many cars especially the ABS (and stability control systems).

The best option is to have the vehicle scanned for fault codes that have been generated and there will be one or 2 if these warning lights are displayed. Scanning the ABS for codes will show up one or more issues and you can trace the problem from there. I think you will find the brake warning and ABS warning have been caused by the same fault.

In any event make sure you check the brake fluid level in the car and look for any external leaks of fluid that may have developed. Check the operation of your brakes to ensure they are working normally and that the brake pedal is not slowly dropping to the floor when you continue to apply pressure. Bleed the brakes if the brake fluid is 2 yrs old or more.

ABS CHECK LIGHT DOESNT COME ON WHEN YOU TURN KEY ON


1. I would not be concerned because if there was a failure in the ABS you would definitely get an ABS warning light and the ABS and most likely the stability control/traction control systems (with added warning lights) will all switch off .

2. You can test if the ABS is operational. On a very quiet damp surface, straight, wide road( with NO other cars around), apply your brakes hard from a very low speed - up to 20 mph ONLY driving in a straight line - until the car stops. The front brakes should attempt to lock up under hard braking and if the ABS is operational you will feel it kick in and the brake pedal will pulsate as the ABS constantly allows brake pressure and then releases it to prevent the wheels from locking up on the damp road. If the ABS does not kick in be ready to release the brake pedal quickly to allow the wheels to rotate so you can steer the car safely. Without the ABS the front wheels should begin to lock up on the damp road surface due to the low level of tire grip. ONLY test this at very low speed and ONLY when driving in a straight line on a straight section of wide road with no other vehicles around.

Abs subaru outback 1999 not light, no error codes but does not work.


Have the abs removed and checked for operation. If you press the pedal hard enough to produce a skid but it doesn't then the abs is working. Under heavy braking from speed you will get a pulsating feeling in the pedal as the brakes are released and then re applied very quickly. If you are finding that no mater how hard you press there appears to be no assistance to brake then the problem will be in the booster and not the ABS.

On vehicles equiped with ABS brakes you have to have the vehicle running when you bleed the brakes if you di it while not running this is the problem you will have. Be sure you start it then check fluid then bleed the brakes really good it usually takes alot of bleeding when you have ABS.

What causes the brake pedal to go almost to the floor and there seems to be no anti lock system


First test the master cylinder.with the engine off. Is the pedal firm. Is it holding pressure.If you say yes the master cyclinder is good. Now turn the vehicle on. does the pedal go to the floor.?.Now the ABS light doesnt have to be on to detect a problem ABS modules do fail. If it goes to the floor with the engine on and doesnt go to the floor with engine off. ABS motor module is no good. Why because the ABS motor pistons are not at it proper postion. Remember engine off we tested brakes without the ABS. Key on engine running we now test ABS. if it sink at this point the fix is a new abs module.Here the thing if you replace the module it will have to be flashed , the engine management will not communicate with it or recognize it

Dash warning light


on the 93 there is a problem with the abs system. there are several things that could be wrong. if i remember correctly the module is behind the passenger side kick panel. you will find a single wire coming off the module. if you ground it then turn on the key it will flash the brake lights in the dash. count the flashes this is the code for the error. it will help in the repair. as for the second truck you have a leak that needs repaired.
