The best thing you can do for a stock or mildly modified car is to run the Ford Explorer rear disc brake package. These kits are cheap, easy to come by, and offer a tremendous increase in stopping power over stock drums. The parking brake system is excellent too, much better than most disc systems that use a mechanism inside the caliper. The Ford system has a small set of shoes inside the back of the rotor, so the parking brake is actually a miniature drum setup.

If you're going to run massive front brakes (like 13" slotted/drilled rotors with 4/6 piston calipers) you should run matching rear brakes, because otherwise you won't be able to properly set the brake bias, even with an adjustable valve.

im still running stock front brakes and intend to run for a long time, the car will be getting a 383 next year so the 9" had to be built , best price i can get on the explorer disk package was $520 CDN.

my other question is if i run the explorer disk system do the explorer calipers have a larger fuid requirement then the stock drums i had?, will this affect braking? how hard will it be to used the ford E brake system on my camaro? and what size are the ford rotors?. if u cna help me on this id be verry appreciative
Chris.

I'm not sure about the fluid capacity of the calipers vs the stock wheel cylinders. You may need to convert to a disc/disc master cylinder to make it work properly. I would consider an adjustable proportioning valve mandatory with any rear disc swap, other than stock. You could call Currie Enterprises about this. They sell a lot of 9" and 12-bolt rears with Explorer discs. The calipers are actually made by Bosch, and are common to certain Jeep products too.

To get the e-brake to work you will probably have to fabricate cables to go from the explorer parking brake arm to the connection between the factory rear cables and the one coming from the lever in the console. This shouldn't be difficult. Classic Tube and other brake line and brake manufacturing places can build cables to your specs. NAPA can also do them here in the states, don't know about north of the border.

The Explorer discs are 11" in diameter and are solid (non-vented).

Hope that helps.
