Parking Brake???????

[attackdog]

Hello all. I have a 2001 Yukon and tested the parking brake the other day and it did not work. It seems like it was very easy to push to the floor. Any suggestions on how to adjust or fix the problem? Thanks.

The parking brake bands need to be adjusted at the rear wheels - Unfortunately the rotors have to come off to do it.

Hope this helps.

Unfortunately, it appears to be a common malady among just about all of GM's NBS full-size SUVs...and more often then not, GM tries to push it as "normal". If you can convince a GM dealership to perform the fix that GMCTech suggested under warranty...they are definitely more customer-oriented than other service departments!

GMCtrech: Parking brake bands adjustment you are
refering is the same as starwheel adjustment or
something else.

where or who can do the warranty service you are referencing here...our dealer is trying to pass off as normal as you say....over time the parking brake keeps getting easier to press to the floor, and doesn't seem to be holding the vehicle like it used to....

I have a 2002 XL and it is still holding...who knows for how long.

Can you take the truck to the dealer park it on a hill, ask the warranty department to stand with his/her foot in front of the tire a, set the park brake without being in park and see what happens?

If you complain long, hard, and loud enough, you should be able to get a dealer to "try" to fix it--I use the word "try" because although after they "fixed" it, the parking brake pedal would still almost go all the way to the floor. FWIW, even in that condition, it still held my truck in place even on a decent incline (e.g., my driveway) and w/ the tranny in neutral...but still, it is a bit unnerving to have the PB pedal practically hit the floorboard in order for the PB to fully engage.

Why would a dealer attempt a repair in which the engineers at GM have stated that there is no correction?mmmmmmmmmmmmm????????

The point is to make the dealer--and from there, the manufacturer--aware that it's unacceptable to have designed such a parking brake pedal which requires it to be--more often than not--depressed practically all the way down to the floorboard before the parking brakes engage. I mean, I betcha there isn't one person who wouldn't figuratively--if not literally--crap in his pants if he discovered that the main brake pedal had to be depressed all the way to the floor in order to engage the brakes; why should it be any different with the parking brake?

Are you putting on youe E-brake the right way?If you look in the manual it tells you,you have to push the regular brake pedal to the floor and then apply the E-brake.Then to release you must do the same.I am guessing it that way because of the rear disc.

Hi All,

Just went out and tried what the "Tony241" post suggested...did not make any difference. Tried in Park, neutral, reverse, drive and it did not hold either direction. My park brake does not hold at all on a 3 to 4 % grade.

Thanks to this forum for alerting me to the fact.

Don't know what I am going to do, but I am going to start and will let all know the results.

I am not concerned for me or those that read this forum, but for the 100's of thoudans that are not aware of it.

We must make our voices heard!! I guarantee lives are in danger...I was astounded!!

Happy Holidays and turn the wheel against the curb if you have one

Mike

Hi there,
I have a 2002 Yukon that has the same problem, In fact it's in th shop right now and they want me to replace the parking brake pads. I hardly drive the vehicle and hardly ever use the hand brake. I noticed that it went right to the floor when I did use it. But this morning as I got in the truck to go have it serviced, I noticed that it went completely to the floor and would not hold when I put the car in gear, the truck started roilling forward freely. Well the dealer is suppose to call me back cause I told him about this forum. I hope they start doing something about this problem and maybe do a recall??? I'll keep all you GMC Yukon owners posted...

Since this thread got bumped, I'll throw in another comment:

FWIW--the p-brake pedal on my '04 DXL can be depressed practically all the way to the floorboard...but it does hold my truck in place on even a decent incline.

[Eggert]

Hi guys,
there was a thread either in this or the Chevy Suburban forum about parking brakes needing a redesigned part (clip?) to keep the brake pad from falling onto the drum and wearing out.

Will try to find it. Take care, Eggert

This Parking Break issue is happening to my 2000 Yukon Denali. Is this adjustment something that can be done at home or do you have to take it in? Just wondering because this seems like it would be dangerous.
roynunez -any word on yours?

Thanks, Josh
