This is my rear disk brake swap. It utilizes small dodge fwd rear disks avalible from cars like the daytona, shadow, spirit, lancer, among others. 2 differen... Show moret versions are avalible, the 14" wheel version has 10 5/8" solid rotors and the 15/16" version, wich is harder to find, has 11" vented rotors. considering that the rear brakes do less than 20% of the braking, going with the bigger vented rotors wasnt a concern, and the smaller solid setup better suited the 92 cavalier front brakes.
this picture shows the stock j-body drum brakes
the daytona backing plate. this is the parking brake, all factory dodge stuff. the parking brake cables are 92 beretta. the spring on the cable was cut down 1" to fit into the actuator, and the eye was cut off the cable. the beretta cables are about 1" longer and are needed to reach the brackets on the axle. the threaded part of the cable for the adjuster had to be lengthened around 3" to work. you can see here that considerable machining was needed to fit the stock j-body hub into the dodge backing plate.
the brake hoses took a lot of figuring out. i ended up with some adaptors, teflon core braided steel brake line and hose ends. left to right is areoquip -3 hose ends, 10mm x 1.0 bevel flair to -3 adaptors to convers the steel line on the body to -3, and 7/16" to -3 banjo fitting adaptors. its takes a bit of work and isnt the cheapest route, but its the only way to go for a reliable setup.
the end result. the calipers are mounted low on the back because of the way the parking brake cable exits the backing plate. there is no real downside to this, the only thing is it may not be astheticly pleasing. as for performance, it stops a little better, but not a huge amount of difference. a master cylender with a larger bore and an adjustable proportioning valve would work wonders with this setup.
