wierd feeling in the front suspension

[derekbitt]

have a 1998 k1500 z71 w/ 150,000 miles. I have a wierd feeling in the front left suspension, it feels like a dull grinding in the brake pedal at the very last part of braking when coming to a stop. it doesnt happen all the time. i think that if someone else drove my truck they wouldnt notice it. it is not really an audible grinding, but i can feel it through the pedal. i have inspected the brakes and there appears to be no abnormalities. I think that the suspension may just be worn, but i was hoping for another educated opinion.
thanks in advance.

I think the abs is the culprit on this one. My truck may have the same problem. Sometimes when coming to a hard stop if I hit a pothole or a bump in the road I can here the grinding noise that you are talking about. With a light feel of it in the brake pedal. It also shows up when I am let’s just say off the beaten path and my tires are spinning at a "high rate". When I step on the brake to slow them down it kicks in. I have read about the front abs sensors being the culprit but also the hub bearings. Maybe someone that has fixed this problem will chime in.

dont think it is the ABS, the feeling is basic and mechanical, and also very subtle. i think of it as braking on a flat but rough road, like old country asphalt road. i could say it is like braking with a very agressive offroad tire tread.
