Drum Brake to KH Disc Brake Upgrade
The Kelsey-Hayes disc brakes are an excellent braking upgrade to drum brakes. However, these parts are relatively hard to find and are quite expensive compared to the cost of upgrading to the slider brakes of the 1973-1976 cars or of the B-Body cars.
The KH brake system had differences in 2 areas. There is a difference in the ball joints from 1965-1969 and 1970-1972. In addition, there is difference in the calipers from 1965 to mid-1968 and from mid-1968 to 1972. The KH disc brakes used the same hubs with left and right-hand threads for 1965-1972 but the 1971-1972 used only RH threads.
Upgrading to KH disc brakes is relatively easy because the upper control arms can be reused and the original rear axle may be left in place unmodified. This upgrade requires the following items:
- K-H disc brake spindles
- K-H disc brake dust shields
- K-H disc brake lower ball joint
- K-H disc brake hub & rotor assemblies
- K-H disc brake calipers & hoses
- disc brake master cylinder (MC)
- disc brake distribution/proportioning valve
- new brake lines, including a new pair from the MC if you have a single reservoir MC
- 14" wheels
