I'm pleased with the way my JL8 front brakes turned out for about $700 (seeing as www.jl8brakes.com
sells the front set for $8K) that I decided to see if I can improve on the $5K they want to charge for the rear.
I got my original inspiration for attempting the front brakes from the Camaro Secrets book, the initial description of the JL8 setup makes it sound like the rear setup was easier to accomplish than the front brakes, but I had most of the parts for the front and the front does the lion's share of the braking, so I started there.
In the book, the fronts needed some parts developed (plumbing, caliper bracket, caliper brace, etc.) while the rear seemed to be an almost bolt on procedure. The book says the HD disc brake rear was a modified B car unit which explains the shortened axles and why the axle tube ends aren't necked down like on a regular Camaro 12 bolt.
To read the description of the rear disc brake development, all you have to do is bolt the Corvette rear end caliper adapters to the axle flanges, use thicker c-locks in the center section, drill two parking brake adjustment holes in the axle flange and bolt everything together.
I know the folks that reproduce the HD disc brake rear ends weld a new brake mount flange to the axle tube and use non-necked down B car axle tubes, but has anyone tried to just do what the book says and bolt the Corvette rear caliper bracket to a regular Camaro 12 bolt rear end and proceed with the build up?
If the Corvette rear caliper bracket can bolt directly to the regular 12 bolt rear end axle flange, at worst I would just have to modify my axles and only bolt on the remaing parts (for way less than $5K).
I was really surprised that nobody makes a JL8 front setup for the same price that they offer a front sliding caliper kit. I have to admit, the JL8 front brake setup performs beyond my expectations and a 15 inch rally wheel fits perfectly.
