Brake Line Locks

[OlllllllOCJ]

First I don't want to spend a pile of $$$... That comes around to needing two lines locks (or maybe not - more research required)... But it would be good to have front and rear independent locks for other fun reasons with a twin stick D300. Cutting brake type functions on the cheap but not nearly as easy to use.

Not sure what you are saying Rick... Any brake line leak scares me and will be fixed before wheeling or driving the junk. I don't take that type of chance.

I have an old military m38a1. The PO put on a Micro. It's a single, but so is the entire brake system.
Push on the pedal, pull up on the knob, let off the pedal, all 4 wheels are locked. It traps the fluid in the lines. It's only come in handy once.

It could be an advantage to having 2 locks, one front, one rear. ie. You could lock the front and power up the rear to crab around something.

But I'd never totally trust it to hold for any length of time. A small leak and ---.

That's why they aren't DOT approved for a parking brake.

Ditto on that.

I don’t like any leaks of any kind or of anything. If I see moisture somewhere it shouldn’t be, I will investigate. On one occasion, while parked in front of a Jeep salvage yard, I found a small amount of a thin yellow liquid on a front wheel. Unfortunately, I had stuck my finger in it just before I realized what it was.

*THAT'S* funny!

My dad told me once while cleaning out his truck (Dakota 4dr) he found something odd in the rear floor. Figuring it was a "Milk Dud", squished it between his fingers and took a whiff...

Evidently 1 of the grandkids lost a little something from the confines of a Huggie!

I have thought about line locks too, but I was thinking of doing them left and right side so that I could lock one side and make a tight turn if needed. Is that even a legitimate idea?

[Jim_Lou]

It's a legitimate idea, but not a very practical one IMO. When you need it will probably not be a good time to stand on the brake.

IMHO, for this type of activity, you'd be better off using divorced lockable E-brake levers to cut the brakes.

That type of micro lock isn't practical for that. You first have to hit the brakes, then lock it.

I've experimented quite a bit with individual braking on buggys.
What you want is cutting brakes like dune buggys use. They are essentially 2 handles, each locking a rear wheel. I've used those for years on buggys. They can be rigged mechanical, pulling on the individual parking brake cables or hydraulic (preferred.)

I've tried hooking them so both wheels on a side lock up, front and rear, not so good at speed. It tends to yank the steering wheel out of your hand, breaking your thumbs! - Yes!

Just the 2 rear wheels individually is fun. You can use 2 handles, or - my preference, the JA-Mar - one handle - a push pull lever.

Sometimes professional rock crawlers use them with 4 handles - one for each wheel. They use them at low speed. Sometimes they need to lock just one wheel to maneuver.

You could do a Google search - look for cutting brakes on dune buggys. There are lots of systems out there.

They are sort of a poor man's locker. But they have to be used with open diffs, you cannot use them with lockers or limited slips.

For a 4 wheeler I'd rather have good selectable lockers.

This tread got me looking at line locks. They seem like they might make a good additional brake while winching.

Here is what I found:

1. Electrical actuated types. All I found are intended for drag racers and only rated to hold for 60 sec. Prices ranged from $40 to $150.

2. Mechanical actuated types. All I found are made by "MICO" not "mirco" and all seem like nice unites. Prices are very steep though and they are hard to find online. $204 for a single line, and $464 for a two line lock. So not cheap!

These seem to be used in agriculture a lot so perhaps they can be had cheaper at farming supply stores.

Addition:

Okay found an other:

manual Called "Park-lok" and only $30. Speedway and BC Broncos both have them. From BC Broncos

Spiffy little thing... Kinda makes you think about how to cable actuate it... Or maybe even a solenoid.

The price is about right for sure.

Manufactured by Jamar (found them doing a search from your link).

Jamar Part# PK1

Thanks, interesting product.
