E-Brake options, Texas Inspection

When I pro streeted my 68 Nova I removed all of the e-brake components, not using one. the car is a back halved car.

I'm moving to an area (Texas) that will requie a safety inspection, requiring the brake.

I'm using '75 Eldo rear calipers but not sure how to go about rigging linkage and cables to use them.

Has anyone used the pinion mounted system, or have any input yay or nay and which is best? I assume a company like TSM would carry a kit for the lever and other parts?

If your rear calipers look like the ones in the pictures below, I used a set of Lokar parking brake cables.

I also used a short floor mounted Lokar emergency brake handle that was installed between the seats. It did NOT have enough mechanical advantage to fully apply the parking brakes. I solved that by fabricating a simple lever that had a 2:1 mechanical advantage. See scanned image below. I installed it below the car. The Lokar cables attached to it and then the linkage from the emergency brake handle attached as well.

The u-joint parking brake unit that is available involves removing the pinion shaft yoke to install. Re-torquing the nut for that must be done correctly to insure the proper pre-load on the bearing.

Frisco your comment about the Lokar E-brake handle struck a chord with me. I have one in my 34 along with the Lokar cables to Wilwood calipers. The E-brake function is all but useless and is barely acceptable for parking. I have complained to Lokar with zero responses.

I used the 16" long trans mount (pull back to apply) in the '28 truck with drum brakes and it worked well.

I used the short floor mounted unit (pull up to apply) in the '30 coupe with the GM calipers that have the built in parking brake (shown in the photos of my earlier post). As I stated, that unit did not have enough mechanical advantage to fully apply the parking brakes. After I fabbed up the intermediate linkage, it was OK. Lokar didn't do their homework on that unit. It really needs to be much longer to function better and be useable for all applications.

Thanks for the input, the pictured calipers are the ones I have.

Frisco or Vince, I'd need the floor mounted setup since I have a large trans tunnel (it's very rigid). Any chance you could put up a picture of a caliper with the cable attached? Wondering if I need to fabricate a bracket off the frame rail to position the pull end of the cable in alignment with the lever.

Next time you go under the car is fine, no rush, I still need to transport this car, it'll be a while before I install.

Thanks for the fast response...

Get antique plates and you wont have to worry about an inspection.

I no longer have the coupe so am unable to get any pictures for you.

The cables are for Wilwwood and Ford Explorer. They attach to the GM caliper by fitting thru the existing mount on the caliper and are locked in place with a nut that comes with the cables. The cables have their own return spring. I used the Lokar return springs in addition to the large return spring that is on the calipers.The stock Lokar mounting bracket for the other end is a simple 'L' shaped bracket that bolts to the floor. I suggest re-enforcing that area with a thicker plate. The cables are easily shortened if required. I suggest that you wrap some masking tape around the stranded inner cable and then cut it with a small Dremel cut-off. The outer cable should be cut in a similar fashion and the end be de-burred.

Below are stock photos of the cables and the short floor mounted e-brake handle. The stock numbers from Speedway Motors for the hand brake is #4917000 and the cables are #49180FU or #49181FU.

Here are two links to the Lokar site as well. The first is for the e-brakes and the second is for the cables.

As I previously mentioned, the short floor mounted e-brake handle does NOT have enough mechanical advantage to fully apply the parking brakes on the GM calipers with the built-in e-brake. I do not recommend using that handle unless you fabricate something similar to what I did (sketch in above post) to increase the mechanical advantage.

These happen to be Wilwood rear brakes, but the cables and connectors are Lokar and appear to be what you need:

....and what the Lokar trans mount looks like finished (without the boot in this photo):

This may be well know to one and all, but I'll throw it out there, anyway.

There are between-the-seat lever-type E-brake actuators that have separate cable connections, one for each side- independently adjustable.

Then there are the single cable type, that uses a single cable back to the "U" cable w/the (usually) adjuster and slider mechanism that then goes to both sides.

At least between the two types, there is some latitude in designing the set-up you want.

Those foot-op E-brakes seem kind of clumsy to mount, might be a pain on a 'glass car. Plus they're heavy, relatively speaking. But they have some travel to them, and mechanical advantage over a hand brake, I believe.

Boy, moving from Anchorage to Texas, that's culture shock! If you can't get your existing set-up working, let me know-I have a new TSM set-up (for a Ford 9")-cheap-

Thanks - it might even be on the road this year but painting and polishing the house to sell so we can move a bit further South is eating my car time -
I haven't seen yours since that batch of pictures you sent me LAST year

You are correct , I have been doing things that are time-consuming and don't show a lot of progess. I got a wild hair (I think that's what it's called ) and decided to finish my Trunk in 6061T6 polished Aluminum-it's about done, and I'll show some pic's when I get there (I made a lot of scrap Aluminum learning how to emboss ). I also bought a tubing bender and put a full inner support system inside-not real sexy stuff, ya know?

That is the one I am using also. I have it actuating the Wilwood hat type E-brake and it hardly engages. I do not know if it's because the handle is not exerting enough movement or the small Corvette type E-brake shoes just don't provide enough friction. I haven't messed with it since I started driving it, several other issues to take care of first.
