Installation Instructions
 | 1. Remove the axle and hub from the rear end housing in the usual
manner. Remove the studs from the hub. Remove the backing plates. |
| 2. Install the rotors on the backside of the hub using the original
studs.There are 2 sets of holes for the two different shoulder sizes. Use
the holes that fit your studs shoulders. |
| 3. Bolt the base brackets to the housing using the (4) 1/2-20 T-bolts,
and Lock 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 spacer in between. (The bracket is spaced to
the outside of the car toward the rotor. Use the 1 3/4 inch bolts, lock
washers and nuts.) |
| 4. Reinstall the hub and rotor assembly and check for runout in the
rotor .010 or less is good. Install the calipers just like the front is
installed. |
| 5. The calipers move every time the brakes are applied & 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.
