Do you have a check engine light? Sometimes a vaccum leak in the airbox/booster will make the abs go all screwy.

What is a abs modular on a Escalade Cadillac?


Jesse, The module will not stop fluid to rear brakes, a bad master cylinder will,leaking lines, air in brake system, faulty metering block if equipped, collapsed flex lines or pinched brake line faulty caliper or brake cylinders,etc. will cause the possible feeling of no rear brakes.
(ABS Module components) the ABS speed sensors and the ABS control module . When the brake is applied, the ABS control module reads the speed data from the speed sensor and sends the correct pressure to each wheel to prevent any wheel lock up, eg. sliding/skidding Links below have more info.

My brakes sometimes go out for no reason. I changed the brakes and the rotors are fine . when im backing up i here this loud grinding noise and my brakes start going down to the floor. what could be wrong.


Your description sounds like a condition called overactive ABS. the grinding nee is the abs pump engaging which will also cause the brake pedal to fade. What is happening is the abs system thinks a wheel is locking up at slow speed even though all the wheels are turning. The abs engages to correct the condition even though there is nothing to correct. Some common failures that will cause this are a bad wheel speed sensor, incorrect wheel speed sensor gap, or a bad exciter ring. The easiest way to figure this out is with a higher end multi-function scan tool capable of reading abs data. With all four wheel speeds displayed drive the vehicle to duplicate the symptom. When the symptom occurs you should be able to see what speed sensor is dropping out. You can then focus on that wheel by checking the common failures. If you have any further questions i'll be happy to answer them.

I think what you are trying to say is the ABS engages at slow speeds when it shouldn't. This is known as overactive ABS.

GM has a technical service bulletin for this. they want you to remove the ABS sensor. Thoroughly clean the mounting surface of any rust/debris. Apply a thin coat of di-electric grease to the mounting surface and reinstall the sensor.

You will need to remove the caliper and rotor to gain access to the sensor. It will be able to remove the bolt with either an allen head socket or a torx socket. Be careful when trying to pull the senosr out. Sometimes the can be pinched into place by the build op of rust. If it breaks off you'll have to replace the wheel bearing hub assembly.

In order to minimize the potential expense of having to replace both wheel bearings you can have the ABS system scanned. Your not looking for codes your looking for data so a high end scan tool will be needed. While observing wheel speed data during a slow stop note which sensor drops to zero first. That's the sensor you should try cleaning the mating surface first.

ABS braking system engages at slow speeds or while


Are there any malfunction lights coming on? If so then it could be a wheel speed sensor. sometimes people confuse rotor vibration with abs pulsation.

My ABS brakes are kicking in when I go down a hill or turn my wheel. Normal stopping is fine, but slow to stop I hear a internal rubbing sound and then the brakes engage. No light on yet. What might...


A wheel speed sensor is most likely the cause, sometimes one wheel sensor might be a little off in its values and the car thinks the wheel is skidding so it activates the anti-lock system. Problems seems to occur more often at slow rate of speed. When you turn the steering wheel it changes the rotational speed from one wheel to the other and the abs computer thinks it's moving at a different rate of speed, normaly the system will compensate for this, but again if the sensor is off a bit and it excedes it's maximum allowance it will activate the system.The sensors are built into the hub assembly on this car. The rubbing noise sounds as if the abs system pump is comming on.( this is normal if in fact this is what's going on with your car). The reason no light yet, is because as far as the abs module is concerned everything is working properly and it's just doing what it's supposed to do.

Anti-lock brakes engaging when not needed


sounds like you have a wheel speed sensor going out.. need to have it scanned to see which one is dropping out and making abs kick in..

Pulsing sound and feel from wheels


Ok, if the wheel bearing assembly was installed incorrectly the wheel would wobble and you would have a disconcerting feeling in the steering wheel. The rotors have to be within factory specs to be turned safely. What I would do is have the rotors checked with a micrometer and replaced.

Brakes grindind at low speed


Sounds like your getting abs activation when its not needed. Most likley one of the wheel speed sensors has failed. You do need to have a scan tool to read the live data from the abs module as the problem is occurring to pinpoint which sensor is faulty. The abs light will not come on because the abs module thinks its just working normally. I'm an ASE certified mechanic and have seen this problem many times on various vehicles. You might have to pay somebody to diagnose it, but replacing the sensor it a very easy task. I hope this helps.

Abs sensor


there is more than likely a piece of rust stuck to one of the front abs wheel speed sensors. this happens during brake service sometimes.

I had the same problem which was diagnosed incorrectly 3 times
Could be one of 2 things you may want to check
Have a tech read your codes
Have the ABS Control Module checked by a technician. If that is ok then make sure they look at the altenator
In my case, I was getting voltage spikes that were shorting out system controls -the ABS Control Module and the battery, etc. Once they put in a new altenator, the problem was fixed.
