Assembly Instructions
DODGE DANA 70 '87 - '93
FULL FLOATING REAR DISC BRAKE KIT
(Will not fit dual rear wheels)
Parts
List
(2) Vented Rotors
(2) 2 Piece Brake Brackets
(8) 3/8 Spacers
(4) 1/8 Spacers
(8) 1/2-20 X 1 1/4 Grade 8 T-Bolts
(8) 1/2-20 x 2 1/2 Grade 8 Bolts
(16) 1/2-20 Grade 8 Lock Nuts
Installation Instructions
- Remove the axle and hub from the rear end housing in the usual manner.
Remove the studs from the hub. Remove the backing plates.
- Install the rotors on the backside of the hub using the original studs.
- 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 spacers in between. (The bracket is spaced to the outside of the car
toward the rotor. Use the 2 1/2 inch bolts and lock nuts.)
- 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.
- 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.
- You must remove the calipers from the brackets and gravity bleed.
(see
troubleshooting sheet).
When 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.
