Outer Limits 4x4 Board

i have a set of gu diffs grafted under my 75 l.c. and have no handbrake as the cruiser one worked from the rear drum brakes. and the nissan is disc rear end so i have a problem. tried fabbing up a disc and caliper setup on the tailshaft behind g-box but it was no good. have heard of a hydraulic handbrake set up that drift cars use.....any1 used one in a 4wd or got any ideas? if i did this would it pass scrutineering at a 4wd comp? thanx

Early Subaru calipers have a cable operated piston actuation mechanism as well as normal hydraulic actuation.

Tru the Build-ups, Nissan, or Toyota section, I'm sure there would be someone that has solved the problem before.

If you want it to be legal you'll need a mechanical caliper, so look at retro fitting an earlier LC drum brake on the back of the transfer. There have been some exceptions (7 series BM use an electronic pushbutton handbrake) but getting t hat legal in a car that previously had a mechanical brake.... good luck. There are also some mechanical caliper disc conversions for hilux cases you might be able to adapt... or just fit GU cables and lever to your cruiser to match the diffs.

If you're not concerned about legality just use a line lock. A good option - (possibly better than any mechanical brake), but not legal.

thanks for the tips. the way its goin it will be the illegal option but i will look into those two ideas.

cheers dane, that looks like the best option. hopefully it fits a 75. i did manage to find a hydraulic handbrake with a locking ratchet set up to that may work. heres a link if anyone else is interested.

I used a EA ford rear caliper which is cable activated. with a early ford laser front disk only had to redrill to fit driveshaft bolt pattern

Ratchet mechanism or not, hydraulic handbrakes aren't legal because they can "bleed down" over time and then release.

A line lock is significantly easier to fit than a hydraulic handbrake and is more useful in a 4WD if you aren't bothered by legality.

Not legal but they work well.
also makes a good cutting brake if you have a rear disconnect

Bleeding down is also the reason you shouldn't use the handle on hydraulic over ride to use as a park brake on a trailer. Pisses me off when people think they need to pull it and lock it on.

well the $1630 price tag for the hoppers handbrake is too steep. it will fit a 75 series as well as 78/79 but thats too dear.

These guys make a disc handbrake kit for landie T-cases which has a good reputation. You could buy a caliper, lever and handle from them, and make your own disc and bracket to suit.

i'm in the same boat with my swb FJ40, i swapped out to a 5 speed and had to ditch the transmission handbrake.

any ideas for mine? i don't want to hijack but its sorta similar
