97 sierra ABS problem

My 97 Sierra when braking normally on (dry roads) will slow down properly, just before you stop, the brake pedal goes to the floor, and just before you rear end the dude in front of you they come back!!!! There is no trouble codes, no air in brake system... If I pull ABS fuse out, everything works mint!!! Also note, that this doesn't happen all the time!!!! Intermittent problem with consistant hair pulling!!!

    Thanks alot for your concern about everyone's safety.... the ABS fuse is out of the truck and it is perfectly safe to drive without the ABS functioning!!!! If there was air in the line, than the problem would still exist with the fuse out!!!! I am also very well aware how to bleed brakes equiped with or without ABS... Trust me, there is no air in the lines!!!

    ABS comes on all by it self at low speed braking, A GM defect with their brakes!!!! Sensor thinks the tires are locking up an puts on the ABS, my advice pull the ABS fuse the brakes work better!!!!!

    Hey thanks there btrapp!!!! so it is one (or more) of the wheel sensors..... I priced out a control module... are you sitting down???? I've got a good friend that works in the parts dept of my local dealership, with her "employee discount" i'm looking at $1277.00 canadian (plus tax of course) just to have it in my hand!!!! I wonder if just cleaning the sensors would fix it???

    I have a 98 GMC 1500 4X4 when braking at 15 mph or under the ABS for the brakes come on with NO ABS light



    Above 15 mph braking is fine. Have changed both ABS sensors in front wheels and it did not help

How do you know for sure there is no air in the brake system. You cannot bleed the ABS breake system in the same manner as a non-ABS system. I recommend taking this to a garage with ASE certified mechanics and have them diagnose the system problems for you. Brakes are essential to your safety and those around you.

When braking on hard surface, just before dead stop, the last few feet, the ABS brakes takes over and the veh caries on a few more feet, finishing with a slow stop. The 4 wheels braking system were bled...


There was a TSB on this issue with your Sierra, a faulty or dirty ABS sensor is the cause of this problem. The fix is simple, just clean the ABS sensor at the front hub with brake parts cleaner and inspect the wire leads. At worst you may have to replace the sensor it self. Good luck

Brake pedal vibrates while braking and doesent stop right away


There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

The pulsating is the ABS system. It's actually pumping the brakes incredibly fast to even the braking to all wheels.
There's sensors at each wheel and anytime it senses uneven braking, it's going to do this. You may want to pull the wheels and check the sensors and all of the connections and make sure there is no debris in any of the wheel sensor areas..

Or you could just pull the fuse for the abs and not have abs but you won't wreck from pulsating pedal.

Abs sensor


No, the pulsing is caused by warped rotors. Look at the inside part of each wheel to see if you're loosing brake fluid. If everything is dry, try bleeding the brakes and check you brake fluid level. If it still does it, remove the vacuum hose from the engine that goes to the brake booster and plug it. The pedal should be very solid. If it bleeds off still, replace the brake booster.
