line lock

[03 Black GT]

who all has a line lock, are the expansive, and how can you just flip it on when you want?

Line locks vary in price alot you can get an SLP for about $130 or a Tci for $40. The SLP is a complete kit switches wiring and brake lines, the TCI you need to get all of the accessories but all of that stuff wont equal the extra $90.

I use the TCI, it works great was easy to install and you can add pressure with the momoentary switch already depressed ( I dont know if the SLP can). As far as the switch I use 2 switches, one to turn on power to the momentary switch. The I step on the brakes hard a few times press and hold the momentary switch and both my front wheels are locked. When I am finishing my burnout I let out the momentary switch and roll out.

They are definetly the easiest way to do a burnout.

Can you expand on this please? I plan on getting a line lock and I'm trying to get a better understanding of how they work.

If you activate the solenoid (press and hold your momentary switch) without stepping on the brakes, what happens?

Are you saying you can step on the brakes at that point and it will apply and hold the front brakes?

With the switch pushed in, can you still apply the brakes?

I have the SLP line lock. I works pretty ok and it simple to use. 1 switch. First you turn switch on,2 press brake to floor,3 do burn out, 4 flip switch off and roll out of burn out. The kit comes with pre-bent lines.

I knew that part. Try this and tell me what happens.... flip the switch, drive in a parking lot at less than walking speed. Then step on the brakes.

Basically some line locks will only build pressure if you are not depressing your momentary switch. With the TCI you can depress the switch and step on the brakes and you will add pressure to your brake system. The solenoid it's self has a check valve in it.

You mean they will build pressure only when you are depressing the switch?

I'm concerned about the ones that come with a toggle switch. If the switch is accidentally flipped over to the On position while driving down the freeway, what's gonna happen? Will the front brakes hold once you first step on them?

A line lock doesn't actually apply any pressure itself, it's basically just a valve that holds the preassure on the brakes. When you step on the brake pedal you are applying the pressure, then when you activate the line-lock it will hold the pressure in the brakes even when you let off the pedal. That way you aren't putting any pressure on the rear brakes (causing wear/tear unnecisarilly) while you are doing your burnout.

With many brands you have to step on/pump the brakes a little BEFORE you apply the lock, with some (like the TCI mentioned above) it doesn;t matter, you can engage it first and then pump the pedal a few times, then it will hold until you disengage the lock.

I guess I'm not making my question clear. I understand how it works when we're talking about locking the front brakes do facilitate a burn out. I'm not sure how it works under accidental activation. I want to learn how it works when you did not intend for it to work.

For example, I'm cruising down the freeway at 60 mph and my retarded friend says, "Hey! What does this switch do?" and flips the toggle switch for the line lock. Let's assume my line lock came with a toggle on/off switch, not a momentary switch. Besides me throwing him out of the car, what happens then?

Does something happen to the solenoid right away?

What happens when I first step on the brakes?

What happens when I release the brake pedal after that?


Thanks.

I don't know if when driving and switch it on by accident and hit the brakes if the line lock will lock up the front brakes. I am not going to find out either. When I'm not at the race track I disconnect it.

I was thinking of putting a second switch, just as a safety interlock. I still want to know what it does if activated while driving around a parking lot.

Ok, I just got a call from Don at SLP in response to my email to them. The soleniod is nothing fancy. It's a simple shut off valve that essentially pinches the line so no fluid can pass. If the solenoid is activated during normal driving, YOU WILL HAVE NO FRONT BRAKES.

I think a momentary switch or an aircraft style safety switch is mandatory.

sorry to bring up an old thread, but i din't wanna start a new one.

Will this line lock work with a 2003 GT???

hmm i wonder what would happen with the tci style that allows you to add pressure with the switch on? any volunteers to test ?? LOL

A buddy of mine got the SLP kit installed. He said it is a check valve. If the system is activated while you're driving, it won't suddenly lock the front brakes. When you step on the brake pedal, the brakes at all four wheels will be applied. When you release the pedal, the rear brakes will release and the front ones will stay applied, depending on how much pressure you applied to the pedal. So basically, you'll stop like normal but with no modulation. (Yes, this not what SLP told me on the phone.)

I'm getting mine installed soon.

yeah i want to install a line lock on my car but i dont want my kids messing with the switch if my girlfriend is driving.

Add one of these from BG Micro. Part No.: SWT1083. The key would only go in when you're at the track. Without the key, the standard SLP switch is useless. I already bought mine. I'll probably add it in later though.

so is the line loc in my link any good????

 

[dallas2002GT]

i need one of these.
