Rear disc brake conversion keeping 15” wheels

Why not a parking brake like on a fbody? That's a rear wheels drive, 4 wheel disc brake car with a ebrake. Would 98-02 fbody rear calipers work? They use a mini drum type setup and the 93-97 fbody used the parking cable to pinch the caliper to the rotor.

Just an idea as they should fit behind stock wheels since the lower models came with 16" wheels like our trucks.

Now to fit 15's some grinding of the caliper might be needed depending on what wheel you run. I know for say Prostars you gotta remove some material but not enough to compromise the caliper.

The 4x4 set up uses stock 88-98 Chevy K1500 front rotors, calipers, and pads. The brackets I made position the caliper at about 2 o’clock on either set up.

The 2wd set up uses AWD Astro van front rotors, with 88-98 Chevy brake calipers.

Brackets are designed for 1-1/4” thick rotors.

Only downside is you will loose the parking brake. You’d have to run a transfer case parking brake which is what I did.

I’m going to post the CAD files tonight when I get back home. Been to busy with the trucks I’m working on to get the pricing situated with my local steel supplier.

Im just about done converting a C2500 6 lug SF to 5 Lug with disc brakes with emergency brakes. It hasn't been a cheap conversion but will be a nice piece when finished. I used the Little Shop Manufacturing rear disc brake setup, it is awesome and it clears my 15" rally wheels.
