2000 S-10: brake functions properly while pedal is held down, but when I remove my foot, the brake is released. The following is not a repair so much as a solution to the basic problem and I guess it won't pass scrutiny of any state inspection.Nevertheless, this idea may skip around the automatic pedal stop malfunction and buy you some time while a proper part replacement is arranged. The release cable ends at the ratchet assembly by the pedal and the lever which receives it can be pushed forward before depressing the pedal thereby engaging the stop which will hold the pedal down and keep the brake engaged. There is no click, or catch evident when the release lever is moved forward and it only moves a little bit. Not the easiest reach from the driver’s seat. Also, the release cable is likely to jump out of its place if you just reach blindly and push. From what I've read on this site, there are some design issues with the ratchet mechanism that commonly lead to failure of the pedal stop function. Hopefully this will help those who still want to park on a hill.

Most parking brake pedals work with a dog and pawl , much like a row of saw type teeth that have a small pivoting stop which catches in the teeth to lock down the pedal. If the pivot does not fully engage to teeth because of dirt or rust the pedal will return to its original position. This may also happen if the release cable in not fully returning. You can try pushing on the release handle rather than pulling and see if your pedal now locks in place. You can lube these parts with a can of spray lithium grease but be sure to protect your carpet and pedals so they do not get stained or become slippery. Mask areas off with newspaper or cardboard. Work the pedal and release cable a few times. It will usually free up any binding parts. I hope this helps!
Airbag light on in a Hummer H3 Dashboard???Here is the fix... Start the engine of your car, set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brakepedal to its fully-applied position with your left foot. Now while you are still holding the regular brake pedal down. Quickly release the parking brake, Pull the bottom edge of the lever, located above the parking brake pedal, with the parking brake symbol, directly rearward to release the parking brake. Make sure pedal snaps hard all the way back releasing the parking brake... If this doesn't work the first try, try it 3-5 times and it shall work... The airbag light will go off...
NOTE: The parking brake pedal is located to the left of the regular brake pedal, near the driver's door. &
The parking brake lever is located above the parking brake pedal, with the parking brake symbol.
Do you mean that the parking brake works when you press the pedal down but the pedal does not STAY down? If this is the case, you should look at the parking brake mechanism to make sure that the lever that releases the brake is not stuck (the release cable attaches to it - SEE PICTURE BELOW). You will have to remove the lower dash cover to do this. Sometimes the lever gets stuck in the "relaese" position when you pull the cable. Some spray lithium grease usually works well in getting it working again.
If the lever is not sticking, then the ratchet mechanism is dammaged and the pedal assembly will have to be replaced. The assembly is only attached to the vehicle with 3 bolts. It can be a little tricky getting the main cable disconnected fronm the old pedal assembly and connected to the new pedal assembly, but other than that it is not hard to change.
I too, have had problems with my '01 s10 parking brake. This brake is not like other vehicals. The regular brake pedal needs to be pressed down before the parking brake can stay down. Same with it being released. It is explained more clearly in your owners manual. Hope this helps! Please rate 4 thumbs up!
My '03 S10 with manual transmission had the parking mechanism fail. I could push the parking brake pedal to the floor and it would not lock in place. To take out this mechanism, pull the plastic sidewall off next to the parking pedal, then unscrew the plastic panel underneath the dash, which is above the gas and brake pedals. The front plastic panel can remain in place. The parking mechanism is held to the sidewall by two lower hex head screws (easy to take out) and one above the pedal arm (this takes patience to remove). Feel around for this upper nut - it's there. I used a small extension on my ratchet with a deep wall socket. The upper nut is attached to a stud and this will align the parking mechanism when putting it back on. Once the mechanism is out, take off the parking and brake release cables, the parking brake wire connection, and you're free to see if it can be repaired. The mechanism on my S10 had one end of the spring off to the side, and once put back into place, the repair was made. Good luck!
The parking brake actuator (the mechanism you press with your foot) works like a ratchet wrench. The pedal has a cresent shaped plate with teeth on it. It pivots on a mounting plate. There is a pawl with a small spring also on the backing plate. This pawl engages the teeth on the pedal assembly to hold the brake engaged (against the large return spring). Stick your head under the dash and look carefully at the parking brake actuator mechanism. See why the pawl is not engaging the teeth on the pedal assembly. Most likely causes are that the release mechanism is jammed "on" or that the light spring which attaches to the pawl is missing (usually from being kicked by some one with large feet) View this mechanism on another GM vehicle with the same style parking brake if you suspect that parts are missing.

If you set your parking brake to the first "click" or as soon as the pedal catches, it will turn off the DRL's but not actually engage the brake. Make sure you stop at the very first point the emergency brake pedal will stay down.
