I have done a little research on line lockers and transbrakes but i am still unsure of what they actually do. As far a s I know, the transbake acts as a clutch for an automatic gearbox and a line locker locks the brakes. Is that the purp :drink: ose for these mods?
havnt herd of the 1st(but i think i may have a theroy) but the 2nd - line locker is a term/type of burnout. basiclly using/adjusting how much brake to keep the car not movin too much while ya right foots going all out trying to destroy your tyers(and cars most the time) edit - im wrong ignore me :whistling
A line locker is not a term/type of burnout, it is a solonoid (usually electric) that is connected to your rear brake line that disables the rear brakes, hence you can stand on your brake and gas pedal (to do a burnout) but you dont bugger your rear brakes or have any drag on the rear wheels (ie only the front brakes work). Not sure about trans brakes, but I think it is a device that is fitted in your transmition which locks it up so you can build the revs up to your stall speed and not have to push hard on the brake peddal and risk your car creeping over the start line (used for drag racing), can any one verify or correct this?. Any while we are on the subject, in cars with ABS does the ABS activate if you have a line locker turned on for a burn out?. Cheers
yeah, the transbrake is a solenoid which holds first and reverse? open simultaneously, then when the solenoid is energised/de/energised, it slams reverse shut you have instant 1st and hopefully some traction...ha ha! and as for the ABS thing, i think it can try and activate the rear brakes, but if the line is locked, it aint doin squat.
ive also seen the line 'locked' in its literal sense. simply a little tap like you have on your house gas system or gas heater on the brake line so the fluid locks against it. fronts will still work backs wont. highly illegal and dangerous.
Nearly everything you said here is perfectly correct. However most Transbrakes i have seen, are actually something very similar to the brake setup on one of your wheels. ie disk and caliper. They fit a smaller, modified version to your tailshaft. Thereby locking the tailshaft, and transmission, holding the car in one spot while you build the revs As for the ABS question, Basically as my understanding ABS works by increasing, and decreasing the brake fluid pressure in your brake lines and calipers, there by applying the brakes on and off quickly to try and stop the wheels skidding , and losing traction. So if you had the line locks turned on, in theory it shouldn't really affect how the ABS works. However braking ability will obviously be reduced greatly, because you rear brakes are no longer active. So your front wheels probably still wouldn't lock up. And well your back wheels will spin forever, cos at that point there is no brakes there. If you want my advice i wouldn't be driving around with a line lock engaged. Cheers Maimu
Nah that'd be dangerous and pretty dumb. I'd love a line locker for my VN calais next week, but then again, VN calais should be able to get smoking pretty easy without one, so long as the 3.8 is in half decent condition. P.S I do not endorse such stupid acts on public roads, I plan to head down to race/dyno/drag/burnout days at the racetracks around melbourne. Also, what is recommended to strengthen the driveline so it can do burnouts without doing as much damage? Strengthened trans? Bigger diff?? How much would it cost too?
If you have any consideration for your brakes, you'll spend the $200 and get a proper line locker. Aparet from not screwing with your rotors, you'll be saving your pads in the long run aswell. come to think of it, over a year and my pads are still new, but i use my gearbox to slow down, not the brakes. Its the cheapest form of locking your brakes, sure you could use clamps, but do that 4 or 5 times and your lines will be stuffed. about what is involved, your best bet would be to buy another cheap car. Spmething like a VL mototr into a little carolla, and a welded diff, and your set!
Thanks Maimu, I have seen the trans brakes that you talked about but never realised that is what they were, I just thought they were a fancy handbrake!. Yes driving around with a linelock on would be a foolish thing to do, I was mainly curious if anything would happen with the ABS system whilst doing a burnout, but from you previous explanation I can't see how it would, thanks
its all good to strengthen stuff but still dont be shocked when things fall off and the car wont drive. they were originally made for sensible driving... boring... but with fun comes broken car bits.
Yeah well what's the worst thing that could go? I mean I can only imagine it putting pressure on things from the flywheel back... Besides, I'm not gonna be a professional burner, I was only actually thinking of doing it once, going with a bunch of mates and making a day of it.
the one you are talking about here is an old style of handbrake...they used to put them on landcruisers and such. a true transbrake holds the transmission in two gears at once, like i said in my earlier post and the trans is released into 1st at the flick of a switch or push of a button.
Line Locks Taps into your brake lines and its as described, an electric solonoid, activated by a switch it closes of the line to the brakes. So if you install it in the rear brake line when you activate the switch you can stand as hard as you like on the brake pedal and the rear brakes will not recieve any fluid. Transbrake A transbrake is not just a solonoid, it also needs a completely different valve body in your tranny, Its activated by a switch and does whats been explained locks two gears together, usually first and reverse so you can take your foot of the brake and your car cant roll out of stage, remember though a Transbrake switch is a push bittun switch so as soon as you let your finger of the button it disengages. This is how they work. You roll into the water and conduct your burnout using your line lock if you have one and then release it and roll forward. Come into stage and as soon as you stage and the other car has staged then you hit the transbrake and take your foot of the brake, on the last yellow let your finger of the button and floor it and away you go with hopefully a green. Dont know if anyone is interested but there is alos other things we do. On my car I have an MSD ignition that has a 2 step rev limit on it, One rev limit is the upper limit and it also has a lower limit. I set the lower limit to 5500 rpm and have it wired to the transbrake switch. So i stage and hit the transbrake switch and immediately flatten the accelerater as far as it will go,

The MSD will drop spark to the cylinders to keep the revs at 5500 rpm and on the last yellow finger of the transbrake and the transbrake releases and the MSD rpm lower limit switches of and away you go to 7500 rpm. If anyone is interested i could post some pics of this and maybe a quick little video of how it works. Trev
I am interested in pics or a video to see how it all goes although I dont think I would be looking at anything like this for a while but it does interest me. Thanx
Thanks for the info clinker42, sounds like a great set up with it linked into your rev limit's on your MSD, I had a rough idea of what they do but that was a great explanation, pic's or video would be fantastic. Cheers
I just took some pics I will get a video but all you can hear is the transbrake soloniod clicking in as with the engine running you cant hear anything lol I have posted some more pics on the following website, the inside pic you can see the transbrake switch on the steering wheel and the coiled lead disappearing under the centre console, then on the transbrake pic you can see the transbrake soloniod going into the back of the tranny Trev http://photobucket.com/albums/a120/clinker42/
