2000 Suburban brake pedal puslating
My 2000 Burban with 128,000 has developed a pulsating brake pedal at very low speeds with light brake pressure at crawling stops. It is very sporadic. I can't duplicate the issue at hard braking. It feels light the ABS is engaging. It makes a noise when the pedal pulses like it's a motor or something coming on and moaning when it happens???? I'm about to replace both front wheel hub units, and also going ta get new front rotors and pads. What else could it be??? Thanks for your input.. Scott

My 99 burb has the shakes too, but only when applying moderate brake pressure above about 30 mph. I know it is definitely worn hub bearings in my case, but there are a couple more things that could cause it too. Like Pikey said, it could be the ABS sensor, or the hubs are so bad that the sensor loses its read on the indicator ring, or the rotors could be warped. Those tiny little rotors that come on the K1500 are notorious for warping because they are so small they get very hot, and the least little error in torquing the lugs will make them get all wiggly.
My Suburban came with 20" Eagle Chrome rims with 285 50 20 tires on 'em. I bought it used, and not because it had pimpy rims. Those rims have an extreme offset and they are the cause of my hub failure. The tires almost stick out from under 2 1/2" fender flares. They're about 12" wide and don't rub the frame or inner fender.

Thanks for your help. I just purchased the hubs last week. Timken brand. I'm also going to install new rotors and brake pads while I'm at it....
