line lock questions...

i have no idea what happened to the other posts I started, but lets try again...

Switched to disc on the new 14-bolt. No more e-brakes. I want to install a line lock on the rear brake line and one on the front, just for holding power. After researching most electrically-operated solenoids, I have found that they are not designed for long, continuous use. So now, I'm just looking for a manually operated line lock valve, something with a small handle. Ideally, I will run lines into the cab under the dash and mount the 2 valves somewhere near where the old e-brake bracketry was. I'm having a hard time finding manufacturers of a valve like this. I saw one on a guys buggy at the ISE at Cal Expo last weekend. He had 2 valves that he used for cutting brakes on his rear axle. Something like that should work. anyway, if you have any input, I'd greatly appreciate it...

Eric

Search brake line lock, micro lock, hydraulic line lock, etc.


Here are some addy's that will have hyd. line locks.

SUMMIT

JEGS

Or your could go to a hydraulic/tractor/agribusiness supply and get a simple lever style hyd valve. I have seen people even use precision ball valves that were rated for 10K pressure as line locks.



Here is a simple hyd valve with a subsequent proportioning valve...

I used a regular Swagelok brass valve (I don't have the part number handy, but let me know if interested), it's rated to 2500 PSI and pretty cheap, cost me about 30$.

Fastenal has them for about $35 in brass or carbon steel rated at 5000 psi, made in Germany, will withstand caustic fluids, typically not in the store so you may have to order it in.

For my 14 bolt rear, I rigged up a small Wilwood MC which is activated by the stock e-brake pedal. For normal braking the fluid flows from the main MC through the small Wilwood unit to the rear brakes. To use the Wilwood unit, I just step on the e-brake pedal. Holds great.

I bought a few "lever" type manual check valves that seemed to work great. But on my last rig I put the e-brake on the back of my 205 from High Angle Driveline works great and it's cable actuated so if you crush/rip a brake line out/off it still works....

I run Biondo electric line locks. They've killed my batteries before but have never leaked off pressure.
