I installed a rear disc brake kit from Right Stuff #MDCRDM1 This kit gives you calipers without the parking brake. I don't have the parking brake anymore so this is what I had to use. The only thing missing from the kit were 1/4'' wheel spacers that I had to buy. My rims rubbed a bit on the caliper and I had to use the spacers. Besides the regular pain in the ass changing the master cylinder / proportioning valve and making up lines and removing the pressure valves from the rear lines. Not to mention the brake fluid leaks and bleeding the lines. It was pretty straight forward. As I was doing this job I thought what a mistake I made. But in the end I'm glad I got it done.
