Replacement and Additional Parts

(2) 79 - 87 1/2 Ton 4x4 Chevy Truck Front Calipers.

(2) 76 - 78 El - Dorado rear calipers with parking brakes, pads, and mounting screws.

1. Remove the axle and brake from the rear end housing in the usual manner.
2. Bolt the base brackets to the housing using the (4) 1/2 – 20 x 1 1/2 bolts and lock nuts (do not use lock washers) The brackets can go forward or backward and in a 45 degree or 90 degree position. Also if you turn the bracket over there will be 2 slightly different positions for the caliper. The rear parking brake calipers have their bleed screw in the 90-degree position and the front calipers have the bleed screw in the 45-degree position. Bolt the top bracket to the base with the spacers between. (The bracket is spaced to the outside of the car toward the rotor.)
3. Reinstall the axle and then the rotor and check for runout in the rotor .010 or less is good. Install the calipers just like the front calipers are installed.
4. The calipers move every time the brakes are applied and as the pads wear. We recommend using a flexible brake hose; this also makes it easier to change pads.

Before you disconnect the rear lines, pinch off the rubber line between the frame and axle. This will keep the fluid in the lines and make it easier when you bleed the system.
