5 ton pinion brake

I saw this while surfing on Epay and wondered if anyone had any experience with them. Looks like they are aimed at the off road rock crawler market, but I'm thinking more of a parking brake on my M51. Thoughts

That,s pretty expensive for just a Rotor,caliper,pads, and a mounting bracket. I think you could fab up something yourself ALOT cheaper. Would definitely work great as a parking brake.

In addition to the regular brakes, I think this would help you stop faster but not as a stand alone setup - no way

I agree with Firefighter - you can go to the junkyard and get all the parts for about 1/3 of that price.

Getting the proportioning right would be a pain. And I'm a newb so correct me if I'm wrong, but isn't a 5ton air brakes and that kit is hydraulic.

if you tried to use that for regular braking you would have that rotor glowing red from the first stop. We've got a wrangler around here on 2.5tons and pinion brakes with 42" tires and the braking is too hard to make it enjoyable for the road, plus you can smell the brakes getting super hot, and that's a much lighter vehicle

I'd want a mechanically engaged brake for a parking brake, and I think you'd have trouble finding a mechanical caliper big enough.

DEFINITELY wouldn't pay that much for a setup. It is pretty easy to fab a bracket for a disk caliper.

As I said in my first message I'm looking for a better PARKING brake, and the M51 has the same brakes as an M35, air over hydraulic. The mechanical parking brake won't hold while dumping on a hill even with new parts, I've already redone the parking brake.

The problem isn't the calipher and mount, it's the rotor. I've looked for off the shelf parts for the rotor and no luck.

As far as the price I didn't plan on paying that much. Give them a while and they'll have to drop the price to a reasonable level or go out of business.

I was thinking of using something like a porta-power to activate the caliper rather than a mechanical source.
