THE ABS LIGHT IS ON BECAUSE THE MASTER CYLINDER HAS FAILED, IF U DECIDE TO REPLACE THE MASTER YOURSELF BENCH BLEED THE CYLINDER BEFORE U INSTALL IT, IT WILL COME WITH ADAPTERS AND INSTRUCTIONS FOR BENCH BLEEDING, IF U DON'T DO THIS AND AIR GETS INTO THE ABS CONTROL VALVES THEN A TRIP TO THE DEALER WILL BE REQUIRED TO BLEED THE BRAKES PROPERLY.

SOURCE: ABS light goes off when I start car, but when I start driving .

take the car to the dealer and have them run a self test of the ABS system computer, this will return trouble codes that will help lead to a quicker repair. This is the 1st part of a successful repair.

SOURCE: Abs/Brake Light ON, although new brakes, ABS still works

I would suspect a speed sensor.

SOURCE: speedometer,mileage does'nt work,abs,traction,brake lights r on

no it does not; this is a massive short in the electrical system and, requires the services of an auto electrician like myself.
take the car in to an ASE certified auto electrical shop and, stop spending money on temporary fixes
the technicians can read the schematics and, fix your car right

SOURCE: ABS light is on. Spongy pedal. ABS pump makes

if the abs pump is making noise you either have an air pocket in it or a bad pump, so this is what you need to do have the car pluged in to a modis and have them run a bleeder program, this will make the pump bleed the air from the system, the problem with doing some of this maintanance at home is sometimes you need specialty tools to do the job right this requires a $8,000.00 computer to make sure the air is purged from the system. call a shop and ask them what they will charge to do this. my shop where i work would charge around $25.00 to run this with the modis...
good luck

99 caravan 3.3 no abs brakes. I have replaced a bad master cylinder and all 4 rusted brake lines. The ABS brake warning light is not on. The van does not pull to one side.


Something is wrong with your statement
it is a 99 caravan 3.3 no abs , then you are on about abs light pump etc
the abs pump only works when the master cylinder is under pressure and that pressure is suddenly reduced by the sensor reading a locked wheel and a valve is opened to release line pressure to that wheel As soon as that wheel starts to turn, the valve closes
while the wheel is stopped and that valve is open , the abs pump kicks in to maintain line pressure otherwise the brake pedal would go to the floor
master cylinders work through a. abs unit and not because of it so if the master cylinder becomes faulty, the abs pump will not operate until a wheel stops turning as there is no line pressure to stop a wheel turning
the abs light may not be on because there is nothing to operate the system to put it on

My ABS light came on then off and is now permanently on.


Unless you are a mechanic take it to be serviced. You don't need abs to brake, the computer defaults bake to old style brakes. You can pump your brakes like we did years ago until you can fix it. But I would seek help there is nothing like abs

BRAKES LOCKUP


one of your sensors is out on your ABS system. What will work until you want to fix it is to pull the fuses for the abs( the one from under the hood) and theres one you can pull from the fuse box on the left side on the dashboard. you will not have abs braking but the petal will not get hard and unless you drive in snow its not a ploblem driving without ABS

I have a dodge caravan that has the ABS and the BRAKE light on the pedal is rally hard but it goes away once in a while for like a day and all over again


Dodge used an ABS system for 2 years that didn't have a vacuum booster. Instead it used ABS pressure from the pump motor for the power brakes. This is the system you have. The ABS pump is mounted on top of the transmission. Is the pump running when the pedal is hard to push? Sometimes the pressure sensor in the ABS module will go bad and the pump won't run. You will get a hard pedal and the ABS light and the BRAKE lights will be on. The code in the ABS control module will be LOW BRAKE ACCUMULATOR PRESSURE.

I am having trouble with the abs braking system on a 1998 chevy blazer. The yellow brake light is usually off for the first few minutes of driving and then comes on and stays on until the car is turned...


the yellow light is warning you that a problem exsists with the abs. unless you are experienced with brakes and abs would highly suggest you take it to a shop.

1998 GMC Yukon ABS light stays on from start to off the engine


Hello,
It sounds like the wheel speed sensor may have been damaged in the process of removing the tire. That would cause the abs light to come on. Ususaly when the abs light comes on it is a sign they won't opperate as abs but only as standard hydraulic brakes. I hope this helps. If you have more questions reguarding this or other conserns please ask me. Please remember high ratings are very important to me.

Thank You,

There is a shift interlock mechanism that only alows the key to come out in park. It is the same mechanism that will not let you put it into gear unless you put your foot on the brake. You cannot safely bypass it.

Jeep Cherokee ABS light is on and now no brakes


Hi laustiin,
When the ABS system fails the brakes revert to standard brakes. The ABS module will not repair this for you.
The master cylinder is not likely to change anything either.
I am assuming that the pedal is full since you didn't say otherwise.
Your problem is most likely the brake booster. pump the brakes several times with the engine off to relieve any built up vacuum. While pressing down on the brake pedal start the engine. If the booster is working properly the pedal will move slightly down then press back against your foot. If it doesn't do this replace the booster.
If this doesn't help reply with more information and I will try to help you out.
Good Luck
