Liberty Rear Disk Brakes for A-Body
I am researching the rear disk brake conversion shown in Mopar Action August 2018 issue. The conversion looks like it will work as stated and give great low cost brakes with reduced weight.
I currently run B-Body drums, 11x3", so they are heavy but do work well. The front brakes are the late B-Body police disk brakes with pin calipers, 11 3/4" diameter. These are excellent brakes with manual master cylinder.
The Liberty rear mount for the calipers are $13 each at LKQ Pick-A-Part in Denver area. Rock Auto has an excellent PowerStop Caliper-Rotor-Pad package with drilled and slotted rotors for $226.79 (KC 219736). The more expensive issue is machining the support to 0.100" thickness on a Bridgeport Mill. I have located a shop that will do this work but need to bring in the parts to get a cost estimate. That I will do soon. Attached is a photo of the Liberty rear brake assembly.
Next issue of Mopar Action will address plumbing and emergency brake issues. I don't know how complex this will be, but Richard Ehrenberg generally has practical solutions to these problems. Glad he is on our side!
This conversion should cost ~$300 when complete. If you use the Liberty caliper/rotor from a boneyard, the cost will be even less. Caliper rebuild kits (seal and boot) are a few bucks. Caliper mounting hardware a few bucks more. This could be a very low cost conversion to modern rear disk brakes.
