Parking brake and its cable?
 
My right rear brake is dragging on my 86 base model. At first I thought it was caliper rebuild time ($85 for one at advance auto) but then I relized if i just didnt set my parking brake it would not drag. So, I was thinking the cable is going bad. I noticed the hayes book said to remove exhaust to replace the cable. If I remove the exhaust it will probally crumble. I realy dont want to spend the money on exhaust.

Any expreience on dripping lube in the cable or something?

My parking brake cable was dragging also. My problem was the little torsion spring behind the caliper fell off. I found a replacement and the problem was all gone, helped on my gas miledge also. I would also try to adjust cable, maybe it is to tight.

Yeah, I am going to try that. That spring is located near the differential?

Thanks! Man forum is fast:)

I get spoiled here.

Probably, your parking brake is set too tight.
To adjust, remove the plastic thing around the parking brake lever. You'll see an adjusting screw on the right side. Remove the locking thingy, and adjust the screw (CCW to tighten) until you rear wheels don't drag anymore when lever is released.

There's not much else you can do to adjust the brakes. As other poster mentioned, there could be some hardware broke/missing at the calipers, but it's doubtful.

There is a simple mechanism near the differential that conveys the parking brake lever action to the 2 wheels. You may want to check that up and lube it, but it's hard to get to unless the catback is removed.

Hope this helps,

You might want to look on the actual caliper as well. There is a little "hook" thing that the cable attaches to. That "hook" is held in place with a coiled return spring. If that spring is broken/missing, the brake will stick. Just follow the cable, and look where it meets the caliper.

rant on -
I didn't think north americans used, or even knew what the parking brake was for! :rolleyes:
Anytime I see someone open their door to get out of a car, you always see the car roll just a touch. Then again, I guess the avarage 'Joe' drives an automatic and believes that sticking the car in 'Park' is all they have to do. Morons.

In fact, id you watch just about any TV show/movie, you always see the car roll when they take their foot off the brake.
rant off.
:D

LOL, yeah I use it. And I used it when I was not supposed to. The car has sat for weeks on end. And what did I do? Let it sit with the parking brake.

Just got the car jacked and looked at her. Looks like the right rear caliper gave up the ghost. Going to get an advance auto rebuilt. At least I have a discount and it has a lifetime warrenty.

Thanks for the replies! I check the parking brake hardware and all springs appear to be there.

The reason I am sure it is the caliper is because i took off the parking brake cable from the caliper and it was still locked. I can't even turn the hub. I can barely turn the thing with tire on there.

On the bright side all of that heat cycling has broken free those stupid screws that hold on the rotor:) Now I just need to lock up my left rear caliper to free up those screws!

If one is gone...Better buy 2 calipers. I'm sure the other one is marginal. Just food for thought!
