    Problem: Heavy shudder upon braking

    Everything is Chinese these days. I did not have problems when they were originally installed, other than the left rear locking up which was due to my install error on the right rear. If this drum is out of round, I will take it back to Napa. I bought from Napa for this reason as they have a 12...

    Problem: Heavy shudder upon braking

    The vibration did not exist when the drums were initially installed. Belief is that the one locking up caused it to overheat and warp. The vibration started recently, like just before the tie rod broke which had me focused on the front.

    Problem: Heavy shudder upon braking

    They are about 3 years old and about 15K miles. No they did not get checked before installing. Do I have Napa do that?

    Problem: Heavy shudder upon braking

    By pulling the parking brake handle and braking moderately, he was able to isolate the braking to just the rear wheels. So when we felt the wop, wop, wop, we knew it was in the rear. It was the left rear that was locking up because I installed the brake shoes incorrectly on the right side with...

    Problem: Heavy shudder upon braking

    Unplugging the ABS did not change a thing other than my ABS and Service 4wd lights turned off. I continued my drive over to Wayne at Eagle Watch Automotive and we went for a test drive. I showed him the shudder on heavy braking. He asked me to brake more moderately. Then he asked me to do the...

    Problem: Heavy shudder upon braking

    ABS light is on. Occasionally it goes off and the system works. I had similar thoughts. I do not have my Tech 2 with me. Tests I did over the weekend indicated the ABS pump motor is shot. I’ve ordered a reman ABS unit which is all that you can get now. I could pull a plug and disable the ABS...

    The spare is brand new. I can try putting that on, but I know the result will be the same.

    Problem: Heavy shudder upon braking

    Same thing happened when I put new balanced tires on the front. They are on in the video. Feel nothing from the tires while driving at highway speed.

    Problem: Heavy shudder upon braking

    Old rotors did it and brand new rotors are doing it. Do not feel it in the pedal nor at stops at slow speed.

    Problem: Heavy shudder upon braking

    This is on my ‘99 Suburban. Have a shudder from the right front upon braking. It increases the heavier I hit the brakes. This was happening before the broken tie rod incident which was on the right front. I rebuilt the front end with new ball joints, tie rods, ES poly bushings on forged...

    ABS Diagnosis and Repair

    Well I traded messages with the seller of the reman ABS units and I confirmed the fit based on VIN #. Pictures show a complete ABS unit with proportioning valve in place and EBCM, so I do not need the o-rings, valve tubes an TTY Torx bolts. Seller has excellent feedback, so fingers crossed this...

    ABS Diagnosis and Repair

    Found this video on the ABS and it is excellent: My ‘99 K2500 failed on the first ohm meter test with a reading of 0.0, which points to a bad pump (windings or brushes creating an open circuit). The pump is mounted to the brake pressure modulator valve (BPMV) which along with the electronic...

    I know this is delayed, but how did these injectors test out?

    What did you do with your GMT400 today...or yesterday....

    Replaced the rear exhaust hanger on the ‘99, as the original had broken its metal band and was on its way to breaking completely. Next I will replace the section of exhaust from the muffler back. Front brake pads arrived today. Front rotors arrive Saturday. So front brakes on Sunday...

    GMT800 Door Pins & Bushings

    The Dorman bushings do not last very long, that’s if you can get them in without breaking them.
