Sounds to me like your ABS is not working. ABS keeps your vehicles wheels from locking up and skidding out of control by controlling the brake pressure that is applied to your cylinders. There is a valve body on the driver side fender well near your master cylinder (follow the brake lines from the master cylinder to the valve body) either the sensor that controls it is bad or the body is bad. In my opinion though I would just be easier on the brake pedal.

Is it all 4 wheels or just the rear wheels that lock up? If it's just the rear wheels it could be grease from leaking axle seals getting on the lining or brake fluid from leaking wheel cylinders.

All wheel drive GMC Yukon Denali brakes locking up...already changed out booster and master cylinder and checked all calipers

I had this problem before with a customer truck it was a bad wheel speed sensor. If you take a volt meter and plug the leads in to the wheel speed sensor wires turn the meter to A/C volts low scale. Turn the wheel one revolution per minute you should get a lease 350 to 500 A/C volts on each front wheel. If you don't replace the sensor. If you do then the sensor is ok keep looking GM had a service bulletin on this problem caused by rust. Good Luck

I have a 1998 gmc 1500 350 vortec. just replaced 8 leaky fuel inj. now it has smoking exhaust no power terrible gas milage . and the plugs on one side of motor r fine but the other side...ALL 4 plugs r...

The 8 leaky fuel injectors might have been caused by a bad fuel return regulator. But, that put aside, the 4 plugs misfiring on one side can be caused by a bad computer or connections to the computer.

Open the bleeders on the calipers in this order and let gravity bleed. Front pass & Driver rear then front driver & pass rear. ABS could be damaged if fluid is forced in to ABS Manifold when depressing piston in caliper. The correct way is to clamp brake line open bleeder then depress the piston. The key word here is COULD,

1998 f150xl regular cab brakes grab

I had a similar problem with the front disc brakes .... had to replace the calipers. In high corrosive conditions the pistons on the calipers can become contaminated and not operate smoothly ... they stick. The same thing can happen to the wheel cylinders on the rear. Try replacing the wheel cylinders on the rear (fairly cheep fix) and if that fixes them then the calipers would be next. Jim
