Chevrolet Auto Park

I didn't think thoroughly enough about the downfalls of the Chevrolet chases when I bought my last motorhome. I've sure thought enough about it since. The previous owner had disabled the system (I still don't know how) so that it does not/cannot apply the brake. Instead of a functional Auto Park, I got a sticky note on the dash reminding me to disengage the brake before I drove off. After missing that step a few times and getting tired of brake smoke, I build an electronic alarm to remind me to take off the brake when shifting out of park . . . and to apply the brake when shifting back into park. The alarm works perfect, ever time; and now I've got the routine down real good. I wish I'd had the alarm sooner.

Now I've go an emergency brake pedal that goes to the floor and a brake that does not hold so good. I'm suspecting that my shoes are toast, so I'm looking at opening the brake up and having a look. Anyone had a go at this? Also, are there parts (such as shoes) available, or should I rely on the local clutch and brake rebuilders? I would really like to see this thing grab really good so I can trust the motorhome to stay put when I've applied the brake.

    I do mine as Richard describes with a brake adjusting tool, you can also use a big blade screw driver. Chock the front wheels and lift the rear wheels off the ground. There is a star wheel for adjustment inside the slot at the top. Adjust until the rear tires can't be spun by hand. Then test to see if it holds on a hill. If you feel uncomfortable with the rear wheels off the ground try a few turns of the star wheel then see if it holds on a hill release the parking brake and see if it rolls freely down the hill, there will be a little brake scraping noise but it should roll freely. You may have to adjust it several times to get it right. I doubt that two times forgetting to remove the brake will wear your shoes down that much, it is not used like regular brakes that wear when applied.

    If your parking brake is adjusted correctly and set correctly you should not be able to easily drive off! One should not need an alarm to remind you!

  • No information on what year or model you have. I had my shop do the parking brake shoes along with a spring kit.
    I didn't want to do it my self because I had heard about issues. They had no problem on doing it.
