transfer case e-brake; what might work?

[rondo]

I've talked to a couple 4x4 shops in town, and they dont' know.

The project is my 2000 Nissan Frontier. On the rear 60 i put on the Chev 3/4 ton rotors and went to disk brakes. Now i think i'll use this as a daily driver but need an e-brake to pass inspection. Been kicking around the 76-78 Caddy calipers but they don't come with the arms and springs, and cores are hard to find.

got me thinking, All Pro at least has a tcase ebrake. Bolts to the driveline in front of the tcase yoke. Mine has a slip yoke eliminator so...

The Q is, does anyone know of a universal tcase kit that perhaps i can use for a frontier or drill out for my yoke? The All Pro kit is over 300 bones and i don't know if i can drill it for my driveline yoke.

Bummer is i'd have to notch the floor and move the exhaust but oh well.

High Angle Driveline sells versions for different tcases but they're over $300

You could always fab up a second bracket on your axle to accomodate a wilwood spot caliper.

I had the same problem about a month ago, I changed out my rear axle and the new axle was not compatible with with my old ebrake setup. I had Mt Logan adapt my new axle to my old pull style ebrake for like $250 and that included all new cables. I use it everyday when I have the truck warm up and it has been great.

Got any pics of what they did? Did they add a second caliper to each side?

Has anyone ever thought of just adding onto or building a separate bracket and adding one of these mechanical calipers

 

[RockMonkey]

Got any specs on that? How thick a rotor can you jam in there?

I am not sure I ran across it a while ago when I was considering building a trailer. it is made for trailer brakes. I just sent an email asking how thick of a rotor would fit. I will let you know when I get a response.

searching online I have found another one that will fit 15mm

It think dana 60 rotors are closer to 30mm though

The rear calipers were already set up for an emergency brake. They had little tabs that are pulled inward by the brake cables when the ebrake is set. Your rear calipers should have something similar for an ebrake set up. I will try to post some pics for ya.

Can't be that hard to find the brackets needed for the Cadi brakes. Mine came with the brackets and the return spring, but I don't remember where I got them. Might be worth a few trips to junk yards.

Spence, i've seen your rig at BHR and i really like it. Haven't seen anything like that for a long time. Always thought those kind of rigs would be great off roaders. Anyway do you have a rear 60? Or pics of the setup?
Unstuck, seen your rig too, and it's AWESOME! But the cadi brakes don't come with return springs or levers from the parts store. So searching the junkyards is a kind of PITA.

Found out Tom Woods has a universal tcase ebrake kit, but has some real drawbacks. First they want you to buy their flange, and i don't care for the way it's mounted. To fit it in my rig i think i'd have to drill it out to fit my flange, then bolt it to the front (instead of behind the flange) between the driveshaft and flange, the way all pro does theirs.

Allpro sells the caliper and rotor seperate from the kit.

Im trying to find a caliper like in the toy kits, to use with an automotive rotor for a pinion mounted park brake on the rockwell.

google is your friend and mine too.

The guys in the link above have big mechanical calipers for $100, plus they have laser cut stainless 8" rotors that are drilled to bolt right onto the driveshaft yoke. You can get a rotor that will bolt right to a 1350 yoke. The rotors are $125, but it doesn't say what the thickness is. The caliper says it will handle rotors from 3/16" to 3/8". This is what I will be using on my rig.

The wilwood mechanical calliper that I posted above can be made to accomodate pretty much any rotor. The "factory" configuration will accomodate a rotor that's .810" thick. The calliper is actually built in 2 pcs. If you need to accomodate a thicker rotor, you can simply build a spacer inbetween the two halfs. Wilwood might even sell these spacers. :greg:

Sounds silly but the Wilwood one looks like the Mountain Bike calipers that we have laying around the shop.
I know that these options could work as a parking brake but my question is how well?

And would they qualify for passing inspection? Being on the pinion or transfer case?

 

[RockMonkey]

So, is it a hydraulic caliper with a mechanical provision? Kinda like the Cadillac calipers? Because I don't see anywhere on the Summit Racing page that it mentions mechanical actuation, but it does say it has a 1/8" NPT port.

They make hydraulic and mechanical versions, but not both on one package. The one pictured is obviously a mechanical versions. They are obviously not intended to be a primary caliper, but I think they'd work fine for a parking brake, and I don't know why it wouldn't be legal if used on the rear wheels. You'd want check into the legalities of a t-case or pinion mounted brake.

Also, I found that wilwood does offer spacers for use with thicker rotors. I've not been able to find any part numbers / descriptions of the thicknesses though.

 

[jdub]

So, would you just fab up a bracket on top of the pinion area?

Any advantages to that set up vs. the t-case location.

The t-case just seems more complicated but the pinion mount seems to have clearance issues with a gas tank if applicable.

Browsing the Wilwood calipers it looks like they're all hydraulic, and some have a provision for a mechanical parking brake (like the one you pictured). I'm just wondering how to use it as only a parking brake. If I cap and seal the hydraulic portion will it form a vacuum in the piston and prevent it from being actualted manually? If I don't cap and seal it, will water get in, rust the piston, and freeze it up? I like the idea, and it looks like it will work, I'm just not sure how to deal with the hydraulic piston.
