So I read the sticky about parking brake or "whatever brake" WoW! I have a 1999 silverado 1500 z71,that was rear ended and frame is bent. So I have just bought a 2001 z71.Had 1200 dollar tires on the 99 so I thought I would put them on the 01. While in the process of swapping out rims and tires I noticed the 01 needs a brake job so I removed the rotors and took and had them turned and bought new pads. I knew the 01 had parking brake problem so I thought I would see why my 99 had a good parking brake,goes about half way to floor and holds good.The 01 goes all the way to the floor and dosent hold. Ther ain't a pennys worth of difference in the thickness of the parking brake pads on the two trucks.While I had the rotors off both trucks I set the parking brake on both trucks. The mechanism just barely moves on both trucks. I'm talking a quarter of an inch. No wonder there is a problem with these trucks parking brake, it is such close tolerance in working and not working.So how do you adjust the parking brake?

The parking brake setup sucks on these trucks,not enough movement in the setup to compensate for any pad wear
There is a star wheel you turn to adjust the pad
If thats stripped/rusted rockauto sells the parking brake assembly

I could never get my parking brake on my 2000 Sierra adjusted to hold very well. I decided to replace the parking brake pads & bought them at Auto Zone.
Inside were instructions on how to install & set the pads.

There was a exact measurement for the distance between the outside edges of the pads across the center of the wheel (widest Point) I set the pads exactly to that measurement, reinstalled the disc/hub, etc.

Now my parking brake alone will now hold my 3200lb. boat on my 25 degree sloped driveway. Never had any luck adjusting them any other way

They all suck on the newer ones.
I have DOT vehicles and no matter what I do they barely hold enough to pass the brake check.
Even new ones had the pedal go nearly or all the way to the floor.
Glad my relic is just drum brakes

Yeah, was gonna say our 2 2006 SS's are drum brake rear with the 9.5" 14 bolt, and the parking brakes work like champs.

A picture saves a 1000 words. Thanks guys for your input. I don't think the auto adjusters work so I bought a kit with all the hardware.Guess I will see if it makes a difference.

Does your star wheel spin freely or does it click?
It is supposed to be tight and click when turned.
There is a part at the back side of the wheel that stays stationary

I Bought a hardware kit that had all that new. I also bought new pads because one of the little clips had failed. I also had rotor turned and now I have a good parking brake. The only thing is neither adjuster was out far enough. They were at lowest possible position. So much for auto adjusting. pos.
