Jamar Question

[JeepAl]

I did some searching but didn't really find an answer to my question.

I just got a Willys 53 CJ3A and it has a Jamar Hydraulic Line Lock. I didn't even know what it was until I googled it, but since it has hydraulic lines connected to it, I figured it had something to do with the brakes (good guess, huh?)! Anyway, how do I know if it's engaged or disengaged? I've read they are crappy and I believe it because the e-brake on my ATV won't even hold overnight (it's hydraulic). The brakes need work, but the Jeep is drivable now and I just want to make sure the Jamar isn't engaged.

I run a Jamar turning brake in mine, and a similar line lock. Are there any electric wires running to it as well, or is there a button on the top of it to press? To set it, you hit the brakes, press the button, and let off the brakes. To take it off, you press the brakes again and it should pop free.
If it's electric, remove the power to it.
If the brakes don't drag a lot, I wouldn't worry about it.

And if it's manual. Press the brake pedal and flip it to see if the brakes hold. These work great in certain situations where you don't have enough hands and feet.

I have watched a few jeeps roll away when line locks are used as ebrakes. Really handy but use with caution.

Thanks for all the replies. I guess I won't worry about it for now since the brakes are working. They don't work very well, but they do work.

My flatfender has a T90 3 speed tranny with over-drive and a T18 twin stick transfer case. I did some rock crawling yesterday and quickly ran out of hands! Once I fix the brakes (possibly add a booster), the Jamar might come in handy at times, but I certainly wouldn't use it in place of an e-brake.

BTW, mine is a manual switch; no electrical wires.

Jamar is the maker, it's a hydraulic line lock.
Jamar makes many products. Also, the T18 is a transmission, the D18 or Dana 18 is the transfercase you have. hermtheoverdriveguy has a dual resivour MC conversion, I ran that and 10" drums for about 3 years, they are the bee's knees.

My bad on the D18 (Dana 18) transfer case. Yes, of course the T-18 is a tranny (but mine is a T-90) and Jamar is the company that makes the hydraulic line lock. I tried the Jamar today and it seems to do what it's supposed to do, at least in my driveway which is relatively steep.

Other than safety reasons, is there another reason to switch to a dual reservoir master cylinder? Looks like my brakes are 11 inch drum brakes but I haven't pulled the rims off yet (hard to measure with the rims on).

If I had 11" drums I wouldn't have gone with discs up front. Mostly for safety on the dual resivour.

Thanks. I'll be looking at everything on my Jeep more closely in the next few weeks when I have more time.

pics please...we luv some pics..

FYI, I took off the rims and the front brakes (the ones I measured) are 11 inch and the rear are 10 inch. Also, the wheel cylinders in the front are 1 1/8 inch bore and the rear are 15/16 inch bore.

I put some pics on Photobucket. Here they are. The ones with snow were taken earlier this month (May) and the other two were taken a week or so ago on a trail near me. I will be painting it soon, but not sure what color yet.
