The aforementioned parking brake thread (Page 1/2)
Doggo SEP 02, 04:25 PM
Hey guys, so if you’ve been following my rear brake saga you’ll know that my next step is the parking brake, which I suspect is bad. The reason for this is that when I pull the lever, the driver’s side will retract the spring, but won’t release it when the lever is disengaged. The passenger side seems to work as intended. It’s at this point that I wanted to take the cables off and show them to you guys and ask if there’s any visual indication that they are faulty. However, there’s one problem with that… I can’t get the damn cable ends out of the clip thingy that holds the two cables together! So, I’ll ask this - is there any way to visually tell that the cables are bad while they’re hooked up to the rig? If I knew they were bad I’d just snip them out but I don’t so I don’t want to go down that path just yet. I also don’t want to go ripping up my interior to get down into the handle boot if I don’t need to. Ill post pictures of what I can see, I suppose.

BONUS QUESTION: When greasing the caliper pins, do I lube just the shaft of the pin or the threads too?

The end of the passenger side cable, the one I think is operating fine-ish (more on that later):




Where the passenger cable runs through the frame? cradle? The rubber coating is like melted here. I can peel that flap back a long ways:




More annihilated rubber coating. Again, on passenger side:




The "clip thingy", the goofy thing holding the two end cables together that I can't get off:




The equalizer:




The driver's side hose. Which, to me looks new. I'm no parking brake rubber coating expert though:




The driver's side caliper spring with cable installed. This is where I think the passenger side may be bad too. I can just ever so barely get enough cable to bring it into the lever, no matter what I do. This goes for both sides. To my understanding it should be fairly easy to get enough slack in the cable to feed it into the lever



Something I forgot to mention: I can pull the passenger side inner cable, and the spring on the cable will retract and loosen, albeit with a good deal of force.

Check Ogres cave. (http://fierocave.shorturl.com/) There are some details on the parking brake operation there.

Is that spring compressed 100% with the brake off?

CLICK FOR FULL SIZE



Just spread the cylindrical "clip thingy" apart a bit, and then push one of the cables towards the center to remove it from the clip.

No, it’s not compressed at all. Is it supposed to be when installing the cables?

the spring is not supposed to be compressed that much. also just pry the clip apart with a flathead screwdriver

Progress is happening here at the doghouse! I've removed the two rear cables, which was a lot easier than I anticipated after reading it was a PITA from other threads. The dog ear tab things cooperated pretty well with me and I was able to hold them down with a screwdriver while pulling the cable out. Now all that remains is the front cable.

We're a pretty good ways into it we've got the trim around the lever off and pulled the boot up to get access to the assembly and removed it's bolts.



However, now we're experiencing difficulty getting the wall trim off, the one the seatbelt is bolted to. I'm trying to follow this write up I found about taking the trim out (Redo a headliner with me) and I'm on like step 3 where he says to put a screwdriver behind the panel and pop it out - " and slip a screw driver behind the panel to release the trim fastner at ear level". But he doesn't really specify where to stick the screwdriver and just can't for the life of me figure it out myself. Here's where I think he's telling me to put it:



But I don't see how that attaches to the frame or whatever the trim is clipped to. Anybody have any advice/experience in taking off this particular trim?

Also, at the cable head in the lever assembly there's some purple silicone grease on it. Am I supposed to lube the new cables before installing them?

I've been told you slide the panel and somehow the clips fall off of the body? I've just pried that clip off of the 84, I've never been able to do it without breaking it and having to jbweld it back together. luckily that rear panel only needs the rear most clips and the screw since the seat belt bolts hold it on for the post part. also you shouldn't need to remove that at all. you can just blindly shove the cable through and around and around and it'll usually enter under the carpet and can be maneuvered with a screwdriver through the carpet carefully. also if the front cable moves free I would not recommend replacing it and instead greasing and then wrapping the exposed metal with alot of vinyl tape. it keeps the salt off really well

By exposed metal you mean the part that’s clipped up against the wall underneath the wheel well splash shield right? And, perhaps unfortunately, upon receiving my new cables from the fiero store today, I found that they all glide infinitely easier than the ones that were already on the rig. So, I think I should go ahead and just throw the new front one in too, no? Also, I noticed that the new rear cables don’t have the springs at the end, the ones that go inside the caliper spring. Is that normal? Is it just a newer design? I can take pics when I get home from work if need be. It’s also got some rubber bits that the originals don’t have on the cables themselves.
