Cheap LS1 Rear parking brake cable mod

Just thought I would pass on a idea I had when converting to LS1 Rear brakes using the stock 3 gen cables for PBR (alum) rear calipers. I made 9.5" long (measure in between the nubs at each end) extension cables. I had to tack weld the cables at each end to ensure the nubs I crimped did not slide off. then used a cable splice that I cut open long ways to slip both old and new extension cables in. Closed it and used a small hose clamp to ensure it did not re-open.
Cheaper than the special cables and in the last 3 years has not failed.



Since I have the car apart for some upgrades it's a opportunity to take a good photo of it...

I did this for a while years back. However, I decided to spend the 100$ on a set from hawks than trust a rigged up setup.

Re: Cheap LS1 Rear parking brake cable mod

Where does a guy get those return springs on the caliper side?? I run the Hawks swap cables on my 91 but as it is they are basically there for looks. I keep hearing stories of the 90-92 had self adjustment in the handle but that's definitely a lie

If your talking about the spring on the end of the cable you will have to get a new cable. My mod is still going strong after 8+ years.
If your talking about the lever in the backing plate. I can't remember for certain but I think the shoe is 1 piece and that acted as the spring on the lever to push it back. I ended up getting the little dust boots for the lever from a late 2000's or early 2010's Chev/GMC 1/2 ton pickup can't remember the part # but they fit without mods as I recall.

I'm talking about the springs at the caliper end of the cable. I'm using Hawks swap cables and they don't come with them at all. I think I found a spring that I can make work

Re: Cheap LS1 Rear parking brake cable mod

I've been waiting 2 weeks for my hawks e-brake cables, they don't work. I will be calling them on Monday. They are the same length as my stock cables. 1991 Firebird Formula with 4 w disks. I have a third gen rear with 4th gen disks on it. Cables on the forth gen come in from the rear so the cables need to be extra long to make the u turn.. Maybe I will just have to do the 9.5" extension.

I also have the Hawks cables but they don't have those little return springs that are on the caliper ends

Re: Cheap LS1 Rear parking brake cable mod

The ones I just received do not have the springs either. Disappointing.

Re: Cheap LS1 Rear parking brake cable mod

It's been 7 years since I did mine with the extensions. Have not had any issues but I will mention the crimp for the ferrules must be really tight or they can slip. An alternative is crimp them with a vice or hammer then just put a small tack weld on the open cable wire ends to prevent them slipping thru.

I picked up some springs that "should" work from Grainger a couple years ago. I haven't put them on yet cause I get rarely use my E brake

Re: Cheap LS1 Rear parking brake cable mod

This shows a Hawk cable partially in place way too short to make the 180 turn and connect to the brakes. How did anyone make this work?

Are you sure you've got them routed the right way?? Try starting at the bracket on the rear end then move forward.

Re: Cheap LS1 Rear parking brake cable mod

I too was never able to get them to work. I tried installing starting rear then front and vice versa to no avail. I will have to go custom.

Hmmm that's crazy. Mine fit absolutely perfectly on my MWC 9". The only issue I had was there were no little springs on the cables on the caliper side

Do you have pics of the springs? Or a part number? I am willing to give it another shot. I do know the cable bracket on my Kore3 brake kit will need to be opened up a touch to fit the diameter of the cable. Other than that, the cable seemed too short.
