trying to get some info on brake line locks???
i got a 76 chevy 1-ton with 4 wheel disk brakes and no proportioning vale, how hard these line locks to install and would i need one for the front and back?? any info thanks

What are you trying to accomplish with the line lock? Generally they are only used for drag racing and they would only lock the front brakes.

i was going to install line lock on my rear brakes to act as a parking brake. im guessing your thinking the same? cause i also have the one ton setup with 4 wheel disc brakes. line lock isnt hard to setup at all

southern gator · 02-01-2011, 10:40 PM

yeah i need a parking brake.

all a line lock dus is you pump up pressure on the brakes and its a block off valve. hold pressure going to ether the front or back wheels.

what part if florida are you from

You can't use a line lock as a parking brake. You will burn up the solenoid and kill the battery in no time. They are designed to be used for very short periods only.

You need a mico lock like the bigger trucks have. I have one on my 86 K30 ex firetruck dump.

I have a mechanical line lock in my 79 c30. It used to be a wrecker.. Works great as a e-brake

spudz · 02-02-2011, 11:42 AM

BTW ford mats were from PO. They are LONG GONE

A guy I work for had a 79 1 ton bucket truck with a micro line lock . It was a 12 v system and was on the front brakes . It worked well as long as the truck was running but it did bleed off when left parked not running. It took us 3 hours to get it out off the woods after it bled off.
They do make a manual version that might work better.

Its actually "MICO" lock but it seems like "Micro" is close enough.
