Yet another rear disc brake thread...

[71GMChevy]

I am building my own rear disc setup on my dana44/dana60 gmc k20 4x4. I am using calipers off a 78 caddy with the e-brake built in. I am going to try using the same rotors as the dana 44 in front. I'm going to waterjet my own bracketry. Anyone think I'm crazy? Anyone KNOW that I'm using a wrong rotor/caliper? I know the rotor size on a 78 caddy is 11.16", but it is a 5 or 6 lug. I can't find a 8-lug rotor that size so the next smallest size rotor I can find is 12.5", the one on the front of the dana 44... It shouldn't matter that the rotors are bigger than the caddy rotors if I have full pad contact on the rotor and no interference with moving parts. I'm just wondering if anyone has done this themselves or if everyone just buys kits...

I think I have read all the threads on the topic and most talk about 12 bolt, 14 bolt ff, or eatons. If I missed something, please point it out. Thanks!

I did one on my buddy's ford bought brackets from ruff stuff for $65 shipped to the house used rotors an calipers from front Dana 44

Yes just use the 8 lug front rotors and the Caddy calipers. That's what most guys use, but some don't like the Caddy style calipers with the e-brake. They say they need to be used often for them to continue to work. I don't think you're crazy.....I've done a few dics brake brackets myself.

I have dana 44 rotors and calipers on my 14 bolt but I don't have the ebrake. have had no problems and they work fine.

I appreciate all the info. Using the ebrake won't be a problem, every time I park my car I use the p-brake because of all the hills we have in SoCal.

ok, i decided to put the stock 3/4 ton brakes on the back and I'm going to use a driveshaft ebrake. the cadillac stuff is getting harder to find and they want an arm and a leg for it. They also have less surface area than the stock chevy brakes.
