Pulsing in front end. Rotors or ABS switch

SublimeDaytona07 · 07-10-2007, 01:44 PM

I am getting a pulsing in our '01 Excursion. I am not sure if it is the rotors or the ABS switch. If it is the rotors, I have looked and seen quite a few different ones. It is 4 wd. Any help would be appreciated.

Pulsation while braking, right? Not while driving? ABS pulsation is usually a very rapid pulsing, while a warped rotor pulsation is directly related to vehicle speed. False ABS triggering usually happens at less than 5 mph and can be caused by metal chips sticking to the magnet on the sensor. Cleaning would get rid of that problem. As for rotors, stay away from the white box, no-name Chinese economy rotors. They're nothing but trouble. Get a name brand like Raybestos PG, Wagner, Bendix, or NAPA Gold. Even better, get a rotor that's D3EA certified and buy the same brand of pads as the rotor.

I have a 2000 I just bought with pulling brakes too. I own a shop and I will let you what I find. I feel its rotors out of round possibly the rears. I'll see if I can machine them first otherwise I will install 1st line rotors. I beleive in 1st line parts when your pushing that kind of weight around.
