Truck not stoping and anti brake is working.

pulsates ARE normal for this truck it means abs is working.
if truck pulls to the right then the LEFT brake caliber is not working right check to see if rusted up... also install NEW calb. BOLTS never reuse old one if one is bent calb. wont slide correctly

two wheel drive for economy 4x4 in the snow or mud

yes the front sensor will collect metal shavings causing this same problem.however you need to have it scanned when the lights are on. auto zone scans for free. the front sensors are in the front hubs. replace as a set as assymblies.

Do you have rear disc brakes?If so .the problem is in the rear brakes.This can happen also with drum brakes,so have the rear checked also.Check the front wheel bewaring assemblys also for movement .up and down.and side ways,any movement other than turning,if much at all could also be the problem.I hope this helps.>>[email protected]

One of the sensors has gone bad and needs to be replaced, the other thing to that would also do that is the ABS sensor is dirty or needs to be re gaped to the speed ring on the hub. There was a issue bulletin with your Tahoe on the ABS activating under 8 km/h. Good luck and hope this helps, if not clean out the sensor with brake parts cleaner and check the wire harness and ABS sensor bracket. Re gap the sensor to the speed ring hub. Here is the bulletin. Anti lock Brake (ABS) Activation at Low Speeds (Clean Wheel Speed Sensor Mounting Surface) #03-05-25-007C - (05/16/2006) 2001-2006 Chevrolet Suburban, Tahoe

First, is the ABS light on? Does it come on when it's doing it? Make sure the brake fluid is full, and the brakes are still servicable, ie, pads still have meat on them. If so, the abs control module or a speed sensor might be on the way out. This is a safety issue, and I would recommend getting the truck to a good mechanic to have it checked out.

Is this a 4 way or 6 way connection system? If your truck is wrong, then all factory equipped trailer package harnesses would be wrong, tell your trailer guy...I don't think so.
Is this the first trailer you have hauled?
Let me know, and we will go from there.
REgards,

Very loose front wheels bearings can cause this.

The most likely cause is rust buildup under wheel speed sensors causing them to dislodge(lift up) from front hubs and read incorrectly. If recall has been performed to fix this problem...You may have to replace the appropriate hub in order to stop the ABS activation at low speeds. Let me know if i can help more.

abs brakes come on when stopping on dry pavement just before coming to a complete stop
