The 2003 Chevy S 10 emergency brake can be adjusted with the emergency brake adjustment bolt. The adjustment bolt will be on the emergency brake pad.
It he emergency brake has slack in it, then you more than likely the rear pads/shoes are worn out. Inspect the rear brakes.
Power assisted disc brakes.
I've got a better question, why is this question in the Chevy venture forum ?
I installed a new e.brake shoes on a 2000 Chevy silverado 1500 4x4. Now I don't know how to adjust the cables so the brake works. How or where is the adjustment on the cables? If it's like my 2003 the adjustment is inside the hub. There's an adjustment wheel just like the old fashion star adjustment on drum brakes. I don't know if they are the same though?
you don`t know?
First make sure that the service brakes are adjusted properly Adjustment nut should be located either at the junction of the cables under the vehicle or at the handle itself (may have to remove trim for access) Pull handle to 3 clicks - wheels should be locked at that position
An 03 would have them all around.
The parking brake on a 2003 Chevy Suburban are adjusted by increasing or decreasing pressure on the spring. This is done under the vehicle, along the middle of the vehicle's frame.
Carefully drive in reverse while Spiking (agressively hitting) your brakes in intervals. Do this a few times and then drive forward, you should feel the difference in the amount of brake peddle you are now using. Repeat as necessary to fully adjust.
How do you change brakes on 2003 Silverado Pick Up?
You have a warped brake rotor(s). Resurface or replace the effected brake rotors.
There is no way to adjust the belt tensioner, if it's not keeping enough tension on the belt the complete tensioner itself will need replaced.
