Installation Instructions
(1) Remove the axle and hub from the rear end housing in the usual manner.
(2) Bolt the base brackets to the housing using the stock bolts and 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 brackets to the base with
the 3/16 inch spacers between. (The bracket is spaced to the inside of the car
away from the rotor.)
(3) Reinstall the hub and then the rotor. Check for runout in the rotor
.005 or less is good. Install the calipers just like they are installed in the
front.
(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.
You must remove the calipers from the bracket and gravity bleed. See
troubleshooting sheet.
