I was wondering why my vette was running slower than normal and it felt like it was pulling something really heavy??!!!! well, I was in such hurry to get to my destination I forgot to remove the parking brake and since i was driving on the freeway trying to go fast. well, I burned my brakes. now they don't work at all. I will be doing the work myself but i was wondering if you guys know how.

 

Maybe the cable became loosen. First try cycling the parking brake (ebrake) up and down 3 times and the system MIGHT fix itself by auto tightening. If not usually on cars w/ disc brakes a separate drum brake system is used for the parking brake. You may of worn the shoes. Here is the GM service manual copy paste.

I have searched and searched for pics on doing this but to no avail. Anyone know where there are any? The one time i used my e-brake i forgot and because the sun was in my eyes and i couldn't see my display i drove it 50 miles before i noticed i had left it on. One would have thought i would have at least noticed a drag but i didn't.

 

I've changed my ebrake shoes... its a single shoe for each wheel. remove everything, clean everything, and then use the magic wire tire method to reinstall the retaining spring..
Ill see if I can find the thread for the magic wire tire tool.. once I removed, cleaned and lubed everything. it took me about 20 minutes to install each mono shoe.

I can add a few tips here as well, sorry no pictures..

I took three wire ties and made them into a 4 in. circle ( meaning : I took an 8 inch zip tie and put the end into the eye, leaving it a circle.

I took the M shaped.. the wire spring
and put one zip tie on the center section, then placed the spring into the backing plat clips. ( at this point , I push the clips in a bit to the backing plate to keep the spring from popping off. With the spring tight to the backing plate, I slipped a zip tie at each end of the M clip.. I fed the three zips between the hub and the Shoe, so I had three loops to grab.
The easiest way I found was to pull each end out and get them onto the shoe... ( BTW is important to close the star adjuster down as low as possible)
I cleaned off the threads of the star and then re-greased the threads .
the trick I found was, once both open ends where in place, I took a screw driver and at the same time pulled on the center zip tie pulling it away from the backing plate. I put the screw driver between the hub and the shoe and placed it on top of the spring right next to the zip tie, I then used the screw driver and a lever the pushed the spring Down and under the shoe lip and your done.. It took me 1 hour and 45 minutes to do both sides. including a complete cleaning and re-greasing and adjustment. also be careful if the bottom shoe guide falls out of the adjuster housing, there is a metal dowel known as the push rod. " Don't loose that pin. its about 1/16 dia. by about 1 inch. it sits in a pocket filled with grease. once you have the shoe tight to the backing plate you can just Cut the three loops and pull them out.
