Pinion mounted parking brake

[70 LS1]

A while back I saw a post about a parking brake that was basically a rotor mounted to the diff pinion and a caliper mounted the diff housing.

Does anyone know about these or where to get some info?

Try this. (The internet and Google are your friends.)

Hmmm.. I see they make one for a Dana 60.. this could solve an issue for me..

Thanks, that was exactly what I remembered.

Any feedback on these, from people who have used them? I'm just curious as to how well they hold. My car is going to be getting a manual trans. swap soon, so if I do go this route for the parking brake, it actually has to do something!! LOL


thanks,

Can anyone here offer a comment on the effectiveness of the pinion-mounted style parking brakes? The leverage on such a small rotor would seem insufficient foe holding a heavy vehicle ...

Anyone? Bueller?

Correct me if I am wrong, but the Ford super duty flatbeds we had at work used the disc brake mounted behind the tranny (as opposed to the pinion). It worked very well, holding the truck, trailer and load on some steep Oregon hills.

Steven, the Super Duty trucks (F-450 1988 to 1997, and F-450 and F-550 from 99 - current MY, and also E-450 vans) use a drum style parking brake attached to the rear of the transmission. Effective, but a big heavy turd of a thing too.

Ed I don't have the rear pinion brake setup that your needing feedback on, but I have TSM's rear disc brake kit on my 14 bolt Corporate rearend. The brackets and hardware are nice quality, thus giving me good service with no problems. I dealt with Skip.

I was a mechanic in the Marines, and the military-spec Hummers use a rear yoke mounted parking brake. It's pretty small in diameter, possibly 7-8 inches (it's been awhile). It held the vehicle no problem, when it was properly adjusted. I might add that the military spec Hummers have TH400's with no park pawl, (it's not good to shove a vehicle out of an airplane in park!) so the transmission isn't holding the vehicle at all.

Thanks for the info, Aaron. Just to clarify, those vehicles had a disc style parking brake on the yoke, or a drum? IMO a drum brake is more effective as a parking brake than a disc.

It was a disc, not quite a quarter inch thick. I was thinking about locating a DRMO auction to see if I could snag a setup and adapt it to my car. I'm sure I'd have to make a new rotor, but I could use the caliper and maybe some brackets & hardware. Here's a parts breakdown:

I would be interested in opinions on this setup also. I plan on using this setup in my car, but like everybody else I am curious how well they actually hold.

Four Wheelers particularly the Toyota and Samarai rock crawlers have been using this set up for years.

Looks like they're selling the ECI Brakes setup, which I had seen before the TSM kit was mentioned. I wonder if it's $100 better than the TSM?

I think right now for simplicity's sale I'm just going to work with the 11" rear discs from the mid-90s Crown Vic / Grand Marquis. These have an integral parking brake system inside the rotor hats, similar to the C3 Corvette. I already have most of the parts for that combo, and it bolts up quite easily to my little 8" axle. Then next year if I want to match up with the big fronts I'm using, and fill up the new 18" wheels a bit better, I'll reconsider my options. Obviously using the pinion-mounted park brake would allow me to use whatever rotors and calipers could be made to fit on the rear with custom caliper brackets.

Thanks for everyone's input.

That's one of the biggest reasons I went with one. I have not setup the cable yet.
