Installation Instructions

Remove the axle and hub from the rear end housing in the usual manner. Remove the studs to take the drum off of the hub.
Install the button head bolts in the aluminum spacers (80 lbs. torque) Press the wheel studs into the hub along with the aluminum spacer
Install the new vented rotors on the hub using the 5/8 flat washers and nuts (100 lbs.)
Bolt the base brackets to the housing using the (4) 1/2 – 20 x 1 1/2 T-bolts lock washers and nuts. 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 inside of the car toward the rotor.)
Reinstall the hub and rotor assembly and check for runout in the rotor .005 or less is good. Install the calipers just like they are installed in the front.
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.

You must remove the calipers from the bracket and gravity bleed. See troubleshooting sheet.
