Big disc brake swap on a 9 inch

[63fordturbo]

Finally bit the bullet and started doing a disc brake swap on my truck as I had an axle seal leaking and twisting axles. Also I wanted to do things a bit out of the norm. It's who I am to prove people wrong. Haha! I wanted to install a big brake set up on the rear of my '63 Unibody.
I have 11" rotors with '70 chevelle calipers on the front and thought I'd go with 13" rotors off the front of a 2004 RAM 1500 with a bracket/caliper setup off a Lincoln Versailles. Ran into just a few issues and thought I'd put them up on here...
First was the RAM rotors had the same bolt pattern (5 X 5 1/2") however use a much larger wheel stud and axle flange. So I machined (with the help of a good friend Greg Peterson) a set of spacers to fill the gap between the rotor and studs. Then Greg the perfectionist he is came up with the idea to fix the floating wheel adapter issue since I actually like to USE my truck. What a concept! And make a billet aluminum center support to take up the gap of the rotor to axle flange gap, center the wheel adapter then get sandwiched in with the wheel... Here are some pics...

Milled it down, drilled out the center for the stud to rotor gap.

Cut them off in the band saw at .250"


Started with 3 3/8" aluminum bar stock

First cut was to fit wheel adapter/rotor

Second cut was to recess into wheel

Third was to cut off the excess.

Fourth milled out the center to countersink over the axle flange.

Heres a back pic of where it will take up the gap between the rotor to axle flange.

Had to make spacers for the considerably larger rotors.

Once I get the brake lines complete and the emergency brake system done, I'll share...

Dude, that's just too cool!

Well, did ya get it plumbed and on the road? You haven't swung by the Casa de Hendo, popping the turbo, so?

Finally got all the lines done, bled and everything working.

Brake pedal is front brakes, clutch pedal is rear brakes. Works exceptionally well! I removed the 10psi check valve from the masters for drum brakes.

Installed two brake light switches so I can just use front or rear and still have lights. These are mounted before the emergency brake so lights are not on with ebrake set.

The black box is a mechanical "Grove aircraft landing gear parking brake). I plumbed both the front and the rear through it so I can lock all four wheels and walk away!

Rear line to a tee then flex down to caliper


Crossover to RR.


Just couldn't help myself. I've always wanted to know what kind of pressures are in the brake system so I silver brazed some fittings together so I could add a bleeder and gauge to see whats going on.

At this angle it looks like I mounted it a little off. Time to slot some holes...

Why not run a dual res master cylinder and have everything in one pedal?

It's just not like me to do what everyone else is doing. Besides I had a four speed manual in her originally, a useless clutch pedal after the auto swap and I was so use to driving it as a stick it's second nature to go for both pedals. Come on how many people can say they can power brake their vehicle at 50 mph and smoke the tires!!!? Hahaha! I can!! (Poor mans line lock)
:laugh:

Another thing I forgot to mention, with the masters split it's like they have to do half the work. The braking is effortless as though I have boosters behind them.

That's cool! I was just curious as to the reasoning. Definitely not knocking it lol

Thanks dude. Seeing your avitar picture, I found it hard to believe you'd be knocking it... Although it's not exactly what your talking about... Haha!
