Anti-lock light goes on & brakes go to the floor had it in to the dealer was told nothing was wrong, took it home light came on again & no brakes, twice I almost killed myself. Took it back to dealer they then found the problem, I was told it was hub bearing worn & rubbing on the anti-lock sensor. I do not think that should make my brakes go to the floor. My brakes were in excellent condition. There were no signs of noise or wear on the hub bearings.

Began applying the brakes as I pulled up to the station building, brake pedal went to the floor and the truck began to shake violently and continued to move forward ( I think the engine also began to race, but it was hard to tell). Luckly the truck came to a stop about two feet before hitting the plate glass window in the front of the station ( the brake was still to the floor). Put truck in park and turned it off.
