Question about 2001 GMC Yukon Denali

1 Answer

Two weeks ago I found the brake pedal suddenly did not keep the normal height and went down to the bottom. It gets back to normal height right now but if I press down the pedal softly it still travels down to the bottom.

Check for fluid leaking at the wheels and at the base of the master cylinder. Check fluid level in the reservoir. If any leaks, replace leaking component and bleed system. If no leaks and reservoir is not low, replace master cylinder. If you don't have experience with these repairs, get some help.

Replaced everything but the power booster. brake light comes on. pedal low. have bleed the brakes. no leaks. pedal still low. but have some brakes just not up to normal position on the break pedal


brake pedal height is determined almost exclusively by the rear brakes adjustment. turn the starwheel adjuster and spin the tire by hand until the tire begins to drag. more for firmer higer brake pedal. it is only too much if you smell the breaks while driving. an initial smell is normal as the shoes burn into position. sometimes you can drive in reverse and apply the brakes sharply for an "automatic" adjustment. but this could take many attempts and will only work if everything is clean and well lubricated.

Spongy brake pedal


I have a 2001 Chevy 1500 4 X 4 that recently had all new pads, rotors, and calipers installed. Since then my brake pedal goes almost to the floor before I get any brakes. I took it back to the shop and they bled the brakes with no better results. I bled them also with no results. I took the truck back and they installed a master cylinder with no results. It's now at the Chevy dealer and they say it's normal - BS! I had good brakes before I had all of the brake parts replaced, no one can figure it out. If you have a load in the truck or if you tow anything you better be looking at the ditch to avoid an accident. The original brakes would put you nose into the windshield and now I could stop it better the Fred Flinstone way. Anyone have an answer????????

sense its a deisel i would go with the vacume pump, diesels don't put out any or very little vacume, if you don't have vacume than booster won't work hense hard peddel. when you say you let up on peddel and hit it again you got better break tells me it is not getting enought vacume to booster. i would go for the vacume pump.

My 03 trailblazer does the same thing and the service dept. told me that it was normal for this model to do that, it has never failed to stop but if your sitting at a red light you can feel the peddle go down to almost the floor but it stops fine and it has done this since day 1 and they say thats normal on the trailblazer.
