| I have a 2001 gmc safari van.approx 49000 miles.i first expierenced my antiloc brake system activating when not needed at slow speeds.thinking this was a little odd and i thought i would need to get it to act up more in order to properly explain what is happening to my service personel.and i thought it was minor as even tho the antiloc system activated the brakes seemed to work fine.untill one day when all i heard was the noise accustomed with the antilock system but the brake pedal went to the floor.after pushing as hard as i have ever pushed on a brake pedal the van stopped. being afraid to drive it anymore i got it into my service dept.who replaced both front wheel speed sensors. | |||
