Homemade Line Lock

[CJason5]

me adn my buddy were tossing around the idea of makign a line lock instead of replacing the parking brake. were thinking of routing the rear line in a way that it went through the firewall and into the dash so that u could put a valve in the dash, then route the line back through the firewall and down to the rear wheels like always. then u could push the brake petal all the way and close the valve. that would hold the pressure in the lines doin the same thing as a line lock. it would just be manual instead the solenoid and all that jazz.

anything wrong w/ this? would it work?

any ideas what kind of valve to use and where to get it

[apeters89]

it probably wouldn't pass the inspection requirements... but the idea sonds fine.

[CJason5]

inspection, ha i live in iowa and there is no way any part of my jeep would pass inspection if we had one

[apeters89]

MUST BE NICE!

As for the valves and lines, get some good metal lines to run through the dash, and you could probably get some valves from a hydraulic shop in town...

??maybe could order some from a tractor supply place?? they usually deal with larger hydraulic lines that you would have for your brakes, but they might know where to get them.

if i could get fittings figured out, would it hurt to use a valve made for bigger lines? I would say no it woudlnt' hurt because u'd still have the same pressure it would just take more fluid.

I drove wreckers for a few years along time ago. This is What they used.

You can buy a park lock from the ads in the back of a Hot VW magazine for about $15-20. They are made for what you want to do. Have one on my jeep - works great.

Shit!!!!! it's like I've been sent to newbie HELL

Manual line locks have been around for decades

OK. The idea is simple. What I want to know is this: Realistically, how dangerous are line locks? How often do the lines break?

Thank you Pyro

I did this on my scout. The line lock and brake bias is on the dash! This mod is old as dirt and cheap as hell. What makes you think the lines are going to break??? Ohh yea you guys have those weak ass non boxed frames

[CJason5]

time to go back to newbie hell....

old scout.... whats the deal w/ ur setup there? y do u have two things instead of just one valve.

sorry i'd never heard of manual line locks i've only seen the electric ones

[Gozuki]

One adjuster, one valve...That way you can reduce the effectiveness of your rear discs, so front and rear lock at the same time. TSM, Wilwood, SSB etc all sell both for pretty cheap, why di@k with making it yourself?

[patooyee]

Nothing really makes me think that the lines would break. I've just heard horror stories about line locks. There was one on here about a guy's toyota who had his parked at the top of a hill when the line exploded and the truck rolled down the hill, destroying it, and his buddy's truck at the bottom. The thread was a long, long time ago.

Where could I go about finding one of these to buy online? I checked summit and all they ahve are ELECTRIC line locks. Manual sounds more effective.

I found the proportioning valves. No problem there.

Also, what about emergency braking? Your just screwed if you need a manul (read: emergency) way of braking.

(PS> This is my first post in the Jeep section, I feel naughty!)

I you run one of these your lines and brake system have to be 100%. If you have any leak or bypas it will allow the preassure to leak down and then you will be in trouble

I have thought about this but I just don't trust hydralics to hold my Jeep on a hill....think of it like this, would you trust the hydralics in a floor jack to hold your jeep up with you under it or do you use jack stands?

I think they are neat as hell but I just can't get over the fear of what may happen while I'm standign under my rig....Man would it suck to get killed by your own ride

[patooyee]

If that's the case you'd use some form of mechanical breaks for general purpose. I know the disadvantages if you lose hydraulic pressure, I just wonder how likely it really is.

Now where is that in my shift pattern? All the way to the right and up above the "R" and next to 2nd? Or is that letter I thought was a big "R" really a "P"?

Its hard for me to fathom someone would trust that littel parking pawl in an aluminum cased transmission, to hold a truck and risk your life, and then other folks would be afraid of hydraulic lines failing???

wow!

[DUG]

I'm personally not a big fan of the using the park paul to hold a heavy rig on a steep hill myself. I like the idea of the brake on and the trans in park together.

As for lines failing....that is not my fear. A leaky wheel cylinder or a seaping connection can cause a hydro-lock brake to bleed down over time. For a few minute thing I think they would be great but if I had to have my rig parked on a incline for more then about 15 minutes I would start to worry....that however is just me.

Here you go.....Brake lock

[CJason5]

jack stands? are those the same thing as my cinder blocks? anyways yeah i only wanted this to hold me on a hilll for short term, anything longer i just throw it in gear and shut it off
