TIP:
BEFORE BEGINNING INSTALLATION, SPRAY ALL FITTINGS & FASTENERS WITH
PENETRATING OIL.
1.
Drum Brake Removal.
a) Raise the car until the tires and wheels clear the floor and support the car on jack stands.
Remove the tires and wheel assemblies from the drum.
b) Pull the brake drums off the axle. If the brake drum will not come off easily, retract the shoes
by inserting a narrow screwdriver through the adjusting slot in the backing plate and back off
the adjusting screw.
c)
Disconnect parking brake cable from the actuator and pull through the backing plate after
compressing the retaining clip.
d) Disconnect the rigid brake line from the back of the wheel cylinder. Always use a tube
wrench on brake lines so not to strip the tube nut. Disconnect the electrical plug from the
back of the hub.
e) Working through the large hole in the hub flange, remove the four torx head bolts that hold
the hub and backing plate to the axle.
f)
Remove the hub and backing plate from the axle and separate the hub and backing plate.
2.
Installation of Caliper Mounting Brackets.
a) The caliper mounting brackets will be sandwiched between the end of the axle and the
backside of the hubs.
b) Place the brackets on the axle pointing toward the rear of the car. The drivers side should be
around the one o’clock position and the passenger side around the eleven o’clock position.
c)
Place the hub on the axle over the caliper mounting bracket and secure using the original
nuts and bolts torqued to 50 ft/lbs. Be sure to reconnect the plug for the ABS sensor.
3.
Installation of Rotors and Calipers.
a) Slide the rotors onto the hubs and secure with two lugnuts.
b) The calipers come loaded with the pads in place and are ready for installation. The calipers
will be installed with the parking brake levers on top. The calipers will be bled through the
special bleeders in the banjo bolts and not through the bleeders located in the caliper
castings.
c)
Slide the calipers into position over the rotors and place one of the 7/16” flat washers
provided between the caliper and mounting bracket at each of the bolt holes to center the
caliper. Secure the caliper with the bolts supplied and torque to 80 ft/lbs.
d) Turn the rotor by hand to be sure it spins freely and there is no interference.
4.
Brake Lines.
a) Disconnect the original steel lines at the flex hose and remove them. Install the new shorter
steel lines and bend them to follow the path of the original lines. The new lines are much
shorter and will only reach part way to the caliper.
b) Connect the flex lines supplied to the caliper using the banjo bolts and copper washers
supplied. Torque to 20 - 30 ft/lbs.
c)
Rotate the flex line behind the shock and connect it to the new steel line. Tighten using a
tube wrench.
5.
Parking Brake Cables.
a) Remove the original brake cables by loosening the cables at the adjuster located in the
center of the axle.
