Sterling Disks
Howdy All,
There was a recent post where someone mentioned disc brakes on Sterling 10.25 or 10.50 full floaters.
I want to do a rear disk conversion; all the kits are based on some semi-homemade brackets and chevy calipers etc... but I got the sense thay maybe there are OEM Ford parts I could fit on my 10.25 rear axle? I'd much rather do that if I could.
I have my 10.25 sitting in my garage for rebuild (new SS lines etc...) so now's the time for mods!

Ruff Stuff is where I go for my disc brake kits. Dan is a great guy who knows his stuff (and is a Pirate4x4 sponsor). Their kits use a bolt-on bracket that requires the Chevy caliper, and '96 E350 rear rotors. The closest to "Ford" you will find in a kit...

we are actually getting ready to do this conversion on a GM 14 bolt FF. we are going to be running chevy rotors and 76 chevy 3/4 ton calipers. you should beable to find someone that makes the brackets.

Shame on me, I haven't done a bit of reading about this yet...but I'm going to ask anyway...
Is there a big weight difference between the stock drums and disc swap?
Also, for folks who need a parking brake to pass vehicle inspection each year...you'll need to add some other type of brake. I was thinking of a driveline parking brake. My '65 F350 with NP435 has a drum brake setup with a ratcheting lever that is mounted on the output yoke from the transmission. Very reliable. Works better than these awful parking brake cables and absolute junk on my 85. I'll try a disc brake driveline parking brake if I do disc brakes on the rear axle in my '65. (It won't be an 8.8 then, it would be a 10.25 with discs)

Is that equivalent to the parking brake system on the super duty trucks? I've been told they had the same setup as the 4x tranny or transfer cases but with that drum brake on the output.
Maybe I'm blurring too many lines, can someone shed some light on what trucks had disc brake setups?

Yes, that's what I've read from my reading also.
The 87-97 F-Superduty's with the ZF5 had a driveline parking brake on the back of a 4x4 ZF5 case. Apparently, removal of the parking brake gives you the ability to bolt a transfer case on...
They had Dana 80 rears with 10 lugs and disc brakes.

Here, I took some pictures of the driveline brake on my '65 with 4 speed NP435.
And the lever in the cab, it's the short one to the right of the shifter.
Here's a link from a google search for "Driveline Parking Brake".

Another option is a Line-Lok like Oreo used. Mounts inline the standard brake lines. Apply pressure to the pedal, hit the switch, and the unit locks brake pressure. My '65 has this setup also, Mico Brake-Lok, but it says "Not to be used for parking brake". So I'm guessing use that, but keep the manual brake applied also just in case.

(im still in disbelieve we have places in North America that don't require a basic vehicle safety inspection at least once a year.scary really when you think about it.)
here's a good one.id pay up for the more expensive calipers so you have an emergency brake.
how much do you value your life,loved ones riding with you,and of course your truck!
remember,cheap line locks = parking brake only.not emergency brake.they will not pass safety inspection as such,because they are just as worthless to you as the peddle is,should a line blow lol.

I like that setup. I've seen a few of the aftermarket setups, but I like the idea of using Ford stock as you can be sure there's one combination of parts that will bolt right up. I was talking to a member about a trade for a ZF from a superduty, maybe that drum brake setup could be incorporated.
Second that. I couldn't believe moving from Nova Scotia to Ontario, that the most populated province in Canada (by at least 200%) didn't require annual inspections, and little NS did. Its a pain even on a daily basis... people driving around with headlights aimed directly into oncoming driver's eyes is a personal peeve of mine. Usually turns out its some sweet old lady that doesn't even realize it.

heres how it goes. the f450 comes with a 4x4 tranny, their parking brake bolts to the back of it where your transfer case would go in a 4x4. so, as long as your 2wd you can run that system. if your 4x4 like me, you get the calipers off a cadillac and run a short extension on your cables to activate the emergency/parking brake. ive got the brackets for the rear disc conversion for my 10.25 just havent gotten the time or extra money to finish it. been blowin it on other stuff lol. but its coming soon. theres also a soft line hydraulic brake extension kit you will need. it threads onto the hard line the drum brake runs and hooks to the new cadi disc calipers.
