Ok as some of you know im here in the "stan" so my mind has some time to "chew" on things and i came up with a super slick parking brake idea for my 47 dodge truck thats getting a t-5 that involved a sye on the tailshaft of the trans a motorcycle rotor samitched between the flange and the driveshaft yoke a bracket to hold a caliper from the same bike (i have a ton of extra harley parts if you couldn't tell) a rear harley mc actuated by the stock lever and a slip- drive shaft. I called around to a few places and it seemes feasible that is until i found this http://www.mooreparts.com/store/pro...-Dune-buggy/?gclid=CKur8cn57bgCFXLItAod_GUAqw it works my pluming it in line with a set of brakes in this case the back ones you step on the brakes push the knob and wham the back brakes stay locked to release you push the pedal and pull the know up so yea I'm going to go this route just figgerd id share with yall it seems like a simple solution if your changing your trans but don't want to swap the rear axel.
A disc brake based parking brake at the rear end input shaft is readily available in kit form for popular rear ends. You certainly could home build such a system, but IMO the hydraulic system it requires is ***bersome and less reliable than a purely mechanical parking brake. It would easy, and not very expensive, to swap rear ends for a later MOPAR axle ***embly that already has the parking brake in the drums. By the way......Thank You for Your Service..........and keep thinking. Ray
I prefer an emergency brake vs a parking brake. In the event the regular brakes fail, you could use a mechanical emergency brake. I had 4 wheel discs in a '49 Ford when a caliper let go during a stop.
my `28 tudor has a cable operated pinion mounted brake like Hnstray mentioned. it is from Street Rod Manufacturing in Colorado. they call it a parking brake and not an emergency brake. it will keep the car from rolling away. in a panic stop it will not lock up the rear end , but will slow you down and eventually bring you to a stop. to be fair , it does have a rather small rotor...maybe 8".....and a small mechanical caliper that i would guess would be from a go-kart. i'm sure your `47 Dodge truck is a lot heavier than my `28 tudor , you may want to go bigger on the rotor and caliper. i'd go with a mechanical caliper too http://www.tsmmfg.com/mb3.html
I like that kit but im not sure what you mean about the hydraulic system i described being ***bersome a rear master off a harley isnt that big and only requires one line ill have to chew on it some more
I like the innovative idea, But have to agree with having a seperate "emergency" brake. I found that the type used on the 8.8" Explorer (and other) rear axels will stop the vehicle very well on it's own. Yes, I did try it ! Happy Roddin' 4TTRUK
How do you intend to retain pressure in the system for parking ? Mico and line lock systems say NOT for parking. Mechanical applied is much better.
@ Jon evans that was made for specially for parking but 36 3 window gave me a better solution parking brake they dont offer one for the dodge but im sure something can be made to work
