Line lock/E-brake alternative - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Big69C20 Toy · 10-17-2002, 02:37 PM

Ok fellas i'm looking at converting the rear of my truck (with the HO72 axle) to disc and dont really want nor think it worth it for me to get the e-brake calipers. Anyone out there make or heard of something that locks up the brakes like a line lock but that you could use like overnight or for some period of time. kinda like a manual solenoid or something i guess. Any thoughts or suggestions? Thanks

i've seen hydrolic ones..but there in line so if you put it inside your cab you would have to run a brake line inside..there just a push - pull knob

Slammed67 · 10-17-2002, 05:15 PM

Well, a line lock won't do you any good if your brake system fails which is the reason for an e-brake in the first place. The e-brake needs to be of a mechanical nature, so it'll activate the brake shoes without the use of the brake lines/master cylinder.

Big69C20 Toy · 10-17-2002, 11:54 PM

hey mooneyes do you possibly have a link or any ideas for places to go. I'd be alright with putting one under the hood or something and then when i park just go set it, i guess i could run one into the cab, it'd be fun to plumb

but worth it i suppose.

Slammed67: i realize that point but i've yet to see an e brake on any of my vehicles that did any good, i can still roll the dang things no matter what i tried adjusting them.

Keep the input coming folks

What about some kind of transmission brake like they have on old Land-rovers. It has a drum on the driveshaft and the back of the gearbox. Not sure exactly how it works or if something could be adapted to suit? You would then be able to use your original handle/pedal setup.

Blackbird's rear disc kit looks pretty slick to me. I know adding the e brake adds $140 to price, but by the time you fab up some kinda line lok you'll probably spend that anyway and then not have an "emergency" brake. If you don't have an e-brake that'll lock up the rear, you need to repair/ adjust it. They're capable of doing that easy. (BTW... the pot IS calling the kettle black, here. My e-brake isn't working currently either...

mooneyes · 10-18-2002, 04:28 PM

Jc whitney's got them and i think some tractor or industrial stores may have them also

**john** · 10-18-2002, 05:42 PM

One thing to consider with a line lock,if the brakes are hot when you set it they will release as they cool off. Saw that happen once resulted in crunched front fender.

*Shane* · 10-18-2002, 07:24 PM

"Line Locs" are illegal in some states if used as an Emergency brake. Not sure if your state has inspections, but this may be something to think about.

Rod · 10-18-2002, 08:54 PM

It was actually an option to have an emergency brake set up on the back of the tranny... like a brake drum that you just expanded the shoes to lock things up.I saw one on a 72 chev with a six cylinder 4 spd.

Lippyp · 10-20-2002, 10:36 AM

The great thing about a transmission brake if you have a 4x4 is that with the transmmission in fourwheel drive it locks all four wheels, not just the rears. Great as a parking brake not so ggod if you do need to use it in an emergency as you have one set of shoes in a smaller drum.

XXL · 10-20-2002, 11:19 AM

I've seen one on Ford rearends that is a single disc on the front of the third member. I'm looking for a link now...

**John Fabris** · 10-21-2002, 02:32 PM

Do a search online for driveshaft mounted ebrake.

Where your driveshaft meets the rearend, you can mount a rotor and caliper, and then you can use your regular ebrake cable to enable it.

I have seen a couple that were made for Ford 9inch rear ends.

Big69C20 Toy · 10-21-2002, 07:25 PM

Great ideas all thanks much, i definately will hafta make some sorta e-brake setup for this thing if/when i convert it.

**JDL** · 11-05-2002, 08:11 PM

How about some thing like this.

mooneyes · 11-05-2002, 08:28 PM

thats basically what JCWitney has but its a push pull instead of a lever

Canada20 · 11-12-2002, 12:56 PM

Shouldn't the trans-mounted e-brake work better even if it is smaller? When applied, it's force would be multiplied through the gearing of the rear the same way HP would be, just decelerating instead of accelerating. Though maybe if you have an open diff, you'd only have one wheel doing the stopping too...hmmm......

yellowgmc · 11-12-2002, 01:43 PM

pick up the newest 4 wheel and off road. they've got an article on installing a disc e brake on the drive shaft. looked pretty slick. you may need a new drive shaft which would kinda kill the cheap part of the plan but it would look killer!!
