Odd question about a line lock?

Labora · Sep 7, 2004

I am thinking about getting a line lock for my car not so much as for using it at the track to do a proper burnout. (but thats another reason) But so I can use it as a hill holder, and the main reason as a extra security step to hopefully slow down whoever may be wanting to steal my car should that happen. :notnice:

My question is do you think having a constant pressure on the hose, fittings, Master Cyclinder, etc. All night is bad for the braking system? It seems like it would be a good security feature but not at the cost of possibly having my brake system fail because of misuse. :shrug:

Thoughts?
Thanks.

How do you plan on keeping constant pressure on the line while you aren't in the car? The switch has to be held to keep the line locked.

If you want a hill-holder, use the emergency brake. It works wonders.

Wasn't aware you had to hold the swtich regardless IF its just a pressure switch. I'm sure that could be changed if I wanted to, to a open/close circuit switch.

And yah ebrake works as a hill holder as well. Didn't work (well) until last night thou finnaly got the cable ajusted a bit.

But if you park on a hill everynight (as I do) whats a lil more insurance gonna hurt. :shrug:

It is just a simple solenoid. As long as it has power going to it, it will hold shut. Should he choose, he can use a toggle switch for the security and hide that, and then have the button somewhere else for burnouts and stuff.

On the line lock I have on my car, the line's pressure is only held while the switch is being depressed. The second I let off that switch, my front brakes are released and my car's brakes operate like normal.

Maybe I don't understand what you mean... :shrug:

The solenoid is electric. (At least the ones I'm looking to buy) I can change the wiring around and make it so the solenoid is open or closed by changing the switch to a different kind of switch setup. Yours sounds like a contact/pressure switch? Basically when you push it down all the way you are completing the circuit there by powering the solenoid and it is closing. So I could just change that to a ON/OFF switch basically. All that is true of course if having it on for 12+ hours won't damage my brake system. :shrug:

But it would wear out the line lock solenoid. Were the hell do you live to worry so much? I got a good safty feature for you. See pic. Put a switch inline with the safty clutch switch so you have to not only depress the clutch to start it run you also have to flip the switch.

from my experiance with a line lock, the battery would take a beating too......those solenoids pull some juice, not a huge amount, but enough.

When I installed my push button start, I did all the math out. For the length of wiring I had in mind, I had to use at least a 14 guage wire, the switch had to be able to hold at least 12 volts, and had to be able to pull at least 3 amps. I ended up searching through the parts bin at work and found a momentary switch that could pull 125 volts and 12 amps. I also used 12 guage just to be sure.

For your situation, you should have no problem replacing the momentary switch with a toggle switch providing you find a beefy enough switch to draw that kind of power for that length of time.

I would use a relay but yeah.

Labora · Sep 8, 2004

Come to think of It I didn't think of how much power they pull I bet it might be too much to have it running all night thou. And your right I wonder if the solenoid itself would wear down quickly seeing as how many feature being "rebuildable". :shrug:

And I don't live in a bad area really, it's another excuse to get a line lock since I don't really need one and am about to redo my brake lines with steel ones anyhow.

And I will have to make a clutch switch like that one! Thanks

Shouldnt be any problems we do it on the sandrails every day...
Heres the style that would work for the purpose you are describing

hope this helps you..(BTW it wont work for burnouts...)

Funny story is since this post I've started working heavily on a 62 Bug and somewhat have come into "The know" of VW's and I saw a similar setup like you posted on a sand rail, but I had totally forgot about me wanting one for a security device.

When I get around to installing a line lock I can use for burn outs I will have to add one of those for sure too! Make towing my car up onto a flatbed a lot harder for any would be thief.

Good to see there are some other people on the board thinking outside the box! Thanks for the post!

HAHA... it would take a lot of extra line and fluid, but you could mount it inside the car. LOL
