Has anyone pull a disc brake e-brake setup on there truck?

 

Not many people have posted the addition of rear disc brakes to their 61-66 trucks but most of those that have used a differential with the rear disc setup already in-place. The e-brake typically uses a special internal drum on the rear disc rotor for a mechanical brake instead of the hydraulic system used by the rear disc. The rear end of these trucks are fairly light with the comparison of the overall truck weight and many would argue that the addition of rear discs don't offer much, if any, stopping advantage over conventional drum however, swapping to the wider drum of the 73 - 79 differential does. One more problem will be getting the proportioning valve tuned so the rear disc doesn't lock up before the front.

 

Well I don't know much about brakes, but I when I bought my truck I noticed that it has 4 wheel disc brakes However the ebrake isn't hooked up....yet

 

I am not talking about putting rear disc brakes on my truck

I am thinking of relocating the e-brake setup to the rear output of the transfer case.

Has anyone done this setup?

 

Oh, You didn't say that, we shoulda been able to read your mind, huh?

Don't recall ever hearing of that being done. Why would ya want to?

For one thing an e-brake setup that is on the output of the transfer case holds a lot better then a standard setup.

Also this type of setup has been done before, they are used on big truck a lot.

 

I had a driveshaft from a big truck or school bus originally on my Merc when I got it, it had been altered to a C6 tranny. It had a drum up on the spline end of the driveshaft that I think was for a drum setup e-brake. Never seen a disc. Check big truck setups in the yards, also where I live there are a boatload of schoolbusses in the yards, try them too.

 

The only problem with that type of set up is if you drop the drive shaft and it takes out the fluid line you have no brakes at all.
I had it happen on my bus on the way home from the auction. I know the ujoint was bad and the shaft bent (former owner ran over something) will it tossed the shaft at 55mph and cut the hyro line i had to coast to a stop hopping the shaft didn't dig in and pogo the 35 foot bus.

PS: bus was made in to race car hauler. sold it cheaper to use the 65

 

You do have a point about dropping the drive shaft. I am going to have to think about this a little more and do some more research.

 

On 4x4 on spike they showed a disk setup but probably not for our trucks
