Dual circuit brake using pinion and wheel brakes.

These pictures if a disc parking brake on a 1943 White 666 .The disc is 14or 15 inches in diameter with two sets of pads . I would like to have this park brake on my M52a2

Just thinking and I am sorry for bringing this topic back up but why not put 6 disc brake pinion brake system on. Two per axle.

Maybe you could but what's your reason? I think we must all have different goals for pinion brakes, my goal would be to have a last resort emergency brake as simple to install and $500 or less....dot approval not important since its emergency/parking use only.

I agree. Should be an improvement. Hydraulic or mechanical? How about air with a maxi can. Then if you loose air presure the brake comes on?

I am loving this topic. While not a deuce guy I would love to switch my drum parking brake and put a pinion parking brake on instead.

For just a parking brake 2 disks on whatever 2 pinions you choose would be a vast improvement over the stock deuce parking brake. And would work well in conjunction with the stock park brake.

For an emergency brake I would think a minimum of 4 disks. Even then I would imagine one shot and they are toast.

Now that's quite a park brake.

Anyone have a good source for pinion brakes, mainly parking brake. Saw boyce equipment has a kit, anyone else?

Diy4x has them as well

Where can you get a maxi can and a air brake caliper?

Pretty much anyone who builds mud trucks and rock crawlers with 2.5 ton rockwells. Just Google 2.5 ton rockwell pinion brake.

I emailed a place out of Louisiana about the calipers they use. Seeing if there is an oem version that will bolt up to their kit that will offer a parking brake option. I'm not entirely to keen on the rotor design as it has the company logo in it but for the price it's not to bad, both 2.5 & 5 ton is 350 for a complete kit.

Wouldn't happen to be krypyonite kustums would it?

Personally I think for our applications converting the drum to disc on the parking brake would be ideal, at least that is what I'm going for. Also air disc calipers are way expensive. Can get a air brake pack and fab up a bracket to pull the tension on the caliper and do the same thing for way less. That's what I'm planing on doing with my parking brake but if I can go disc I will be happier than a gator with a toothbrush.

If you just want a disk parking brake I would put 2 hydraulic calipers on one disk behind the transfer case and have a hydraulic parking brake. It would be simple and almost fool proof.

Biggest thing is the rotors, what lines up to the pinions, both 2.5 & 5 ton.

I was under the impression that holding pressure on hydraulic brakes for long periods of time isnt recommended.

If I could do that I would put a line lock on the front drums instead.

Hmm ya a mechanical caliper might be a better option. I'm not really sure what one of those would cost. I think on a deuce you could use the same rotor as a pinion brake. 5 ton I don't know.

There are trucks that use a caliper as the parking brake ( in fact some of our "Ford baby busses" used them) . The park lever pulls a cable that actuates a cam-over block that presses on the caliper ( picture a large vise-grip). I have worked on them before. Pretty simple, but I wouldn't trust my life to them. Of course in an emergency I would use anything at my disposal !

I think I'm going to try making a "last resort" brake and I'll see how it works. I'm thinking 2x rotors (12") with 2 calipers each. Both rotors mounted to the center axle's pinion. If it works and ever gets used, then replacement rotors should be all that's required.
