While researching ways to implement a security system for my car to prevent theft I came across this idea of an inline check valve to lock the cars brakes while you are away. This would prevent someone from just hooking a tow truck up to your car and towing it away. Has anyone else heard of this, or have more information about how it could be accomplished?

I found the initial idea here:

It would stop a tow truck but a rollback could still drag it on. Making these old cars theft proof is tough. Even the new cars with all the hitech chips get stolen.

ummm . . a line lock? They aren't made to be operated continuously, and will drain the battery if left on. whoever wrote that article had little idea of what components to use, but just a 3 second idea. plus i would not like that unit to fail when i am driving. there are better method to secure your car


P.S. If you use a flatbed, you can winch it up onto the bed with the tires locked up. repo men still do it. Why not just buy a boot for one wheel? :)

The best idea is not to use the LineLok to keep the brakes on while you have the car parked, but to fix it so it actuates the first time the thief uses the brakes when he is stealing it. That way, the first time the thief stops the car at the street or in traffic, the brakes don't release.

You may get a call from the cops that your car is blocking traffic in the street, or the battery may run down after the thief abandons the unmoving car, but that is better than having the xar stolen.

The link is dead, but the article wasn't referring to an electronic line lock. It was an inline key cylinder that when locked, applying the brake would keep pressure in the line until the key was unlocked. The ads were all over the magazines in the 1990s and I don't know if they're still around or what it's called now.

It's a little cumbersome and requires some continuing maintenance steps; but my favorite would still be a well-trained, well-loved, extremely faithful and protective Rottweiler in the back seat. :p I know a local "repo man"; and he'll deal with pit bulls any night; but a "middle-aged" female Rott (preferably one that was raised from a puppy by the owner and has had a least one litter of pups of her own) in the yard will just make him walk (run) away. "They just don't care about anything except keeping what is theirs!" My wife has had two female Rott's, and he's right.

That is a "high-maintenance option", though. A manual line-lock, properly-adjusted jiggle switch alarm, and a "Lo-Jack-type device" are all good fun.

A buddy of mine woke up to hear his 4x4 driving off. Three County S.O. cars rolled up to a garage 2 miles away, as the crooks were ripping his stereo and Ham Radio gear out of the cab. In the middle of the pack of cop cars was my 4x4; my buddy in the back seat watching his laptop/GPS/radio assembly and giving directions to the Deputy riding shotgun. Crooks hadn't gotten to the last radio (in his toolbox with its own battery) yet....... :p
