98 Yukon Brakes

35

Asked by Dec 13, 2007 at 05:46 PM about the 1998 GMC Yukon

Question type: Maintenance & Repair

My 98 Yukon front brakes lock up in the last ten feet while braking. ABS light works on startup. No OBDII trouble codes. Brakes do not give a problem if I run the vehicle up to about 40 mph and brake hard. But when we get to about the last five or ten feet, they lock hard, even when using a soft pedal. Pads and rotors are good grade and rather new 20K miles. Could this have something to do with 4WD? A real nuisance to drive in slow moving traffic. Any help or ideas would be welcome. Thanks.

Have you had the brake fluid changed lately? Within a year or two, brake fluid can absorb enough water out of the atmosphere to be almost 50% water. This greatly detracts from braking ability. How about the brake hoses? The rubber lines can degrade inside and collapse, causing them to form a sort of one-way valve -- they can either stick, or lock up like this. I'd suspect the calipers or another mechanical component. Have the brake system checked out by a mechanic who can do a fluid pressure test of the braking system.

Yeah. Changed the fluid in Nov. Used good quality dot3-4. Hoses, no, did not replace--good thought. Did replace the rear wheel cylinders. But did not rebuild the fronts. I use anti-seize on the sliding shafts.

I know this is an old post... but, i have an answer. It MAY need new front Wheel Speed Sensors. common problem with these trucks. You need to remove the front wheels, brake calipers, and rotors. once the rotor is removed you'll find a sensor held to the hub with a 'allen' head bolt. what happens is corrosition builds up under where the both is and causes the sensor to bend. remove the sensors, carefully sand the mounting surface and apply a small amount if dielectric grease and install some new sensors. there is a GM bulliten about it.
