TIP: BEFORE BEGINNING INSTALLATION, SPRAY ALL FITTINGS & FASTENERS WITH PENETRATING OIL. 1) Drum Brake Removal a) Raise the truck until the tires and wheels clear the floor and support the truck on jack stands. Remove the tire and wheel assemblies from the drums. b) Slide the brake drums off the ends of the axles. If the drums 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) Remove the brake shoes and all the hardware. d) Disconnect parking brake cable from the actuator and pull through the backing plate after compressing the retaining clip. e) Disconnect the rigid brake line from the back of the wheel cylinder. Always use a tube wrench and plenty of penetrating oil. BE CAREFUL NOT TO GET BRAKE FLUID ON THE PAINT. IT CAN CAUSE SEVERE DAMAGE. 2) Drum Backing Plate and Axle Shaft Removal a) Remove the rearend cover from the differential and drain all fluid into a drain pan. b) Remove the pinion shaft lock bolt. (7mm hex) c) Slide the pinion lock shaft out of the differential. d) Push the axle shafts inward and remove the C clips from the ends of the axle shafts. e) Carefully slide the axle shafts out of the rear end housing begin careful not to damage the axle bearings or seals. f) Remove the four nuts that hold the backing plate and remove and discard the backing plate. 3) Installation of Caliper Mounting Brackets a) The caliper mounting brackets are identical. When they are mounted to the end of the axle tube, the top edge should tilt towards the front of the truck. b) Secure the brackets to the ends of the axle using the original hardware. Torque the bolts to 40 ft / lbs. c) Slide one of the 7 /16 bolts supplied into each of the four holes on the outside of the caliper mounting bracket. These bolts should be installed from the outside. d) Install the caliper mounting straps over the 7 /16 bolts. The two straps with the semi-circular reliefs will be used for the bottom to clear the axle and flange. The straps must point towards the rear of the truck and the ends must point in towards one another. e) Install the parking brake L-bracket to the upper front 7 /16 bolt on the passenger side. f) Secure the assemblies with the 7 /16 elastic stop nuts and torque to 60-80 ft./lbs. 4) Installation of Axles Shafts and Rotors a) Slide the axle shafts carefully back into the rearend housing. Reinstall the C-clips, pinion lock shaft and pinion lock bolt in the reverse of removal. 1
BE SURE TO INSTALL A NEW DIFFERENTIAL GASKET AND REFILL THE REAREND WITH THE PROPER GEAR OIL TO THE PROPER LEVEL. b) Clean the rotor thoroughly with brake cleaner to remove the packing material. c) Slide the rotors into position on the ends of the axle shafts and secure them with at least one lug nut. 5) Caliper Mounting a) Install the hollow block end of the flex hoses onto the caliper using the hollow banjo bolts with bleeder screws and copper washers provided with the kit. Orient the hoses so they will point towards the axle tube and torque the banjo bolts to 20-30 ft / lbs. b) Place calipers over the rotors with the parking brake levers on top. Note that the bleeder screws in the banjo bolts will be used for bleeding the calipers not the bleeders in the caliper castings. Secure the calipers to the mounting straps using the 12mm bolts supplied. Torque the bolts to 80-100 ft / lbs. 6) Brake Lines a) Remove the original steel lines from the original rear flex hose. Be sure to use a tube wrench and plenty of penetrating oil. b) Connect the new steel lines suppled with the kit and bend them so they can be connected to the flex hoses at the caliper. c) Secure the new lines to the axles with the original line clips that are welded to the axle. MAKE SURE THE FLEX HOSES TAKE A SMOOTH BEND AND DO NOT BECOME KINKED OR TWISTED. 7) Parking Brake Cable a) On the passenger side, pass the parking brake cable over the rear axle and through the L-bracket and lock the outer cable housing into the L-bracket. b) Slide the inner cable through the caliper casting and slide the end of the cable into the parking brake lever on the caliper. c) On the driver s side, remove the factory brake cable and replace it with the new parking brake cable provided in the kit. d) Slide the inner cable through the caliper casting and slide the end of the cable into the parking brake lever on the caliper. The outer housing of the cable will butt up against the loop on the caliper casting. 8) Master Cylinder (kit A158 only - 1994-97 trucks) a) The factory master cylinder does not produce enough volume to supply the rear disc brakes. The factory master cylinder must be replaced with the new high volume unit that is supplied with the kit. b) Remove the old master cylinder by disconnecting the steel lines and removing the two nuts from the studs on the brake booster. The old master cylinder can then be slid out of the engine compartment. c) Before the new master cylinder can be installed, it MUST be bench-bled off of the vehicle in a vise using the bench bleeding kit supplied! d) After being thoroughly bend-bled the new master cylinder can be installed in the reverse removal. 2
9) Distribution Block Modification a) Follow the steel brake line from the smaller bowl of the master cylinder to the brass distribution block. b) Use the vise grips or an adjustable wrench to hold the block securely. Then remove the large nut from end of the distribution block. Make sure you remove the nut from the half of the block that feeds the rear brakes. Use caution since the nut is spring-loaded! c) With the nut removed, remove and set aside the spring from inside of the block. Pull the rubber seal of the piston and set it aside as well. d) Take the piston and push the larger end into the hole of the end nut that was removed from the distribution block in Step C. It will snap into place. e) The end nut can then be threaded back into the block and tightened down. Make sure to re-install the bolt holding distribution block to the bracket. NOTE: DO NOT LET THE MASTER CYLINDER GO DRY DURING THIS OPERATION. STOP AND TOP OFF THE MASTER CYLINDER IF NECESSARY. 10) Filling and Bleeding system a) It is advisable to replace the brake fluid if the color is brown or muddy. This is due to water that has been absorbed by the fluid which will eventually corrode the brake lines and master cylinder. This absorbed moisture can also cause a vapor lock situation under extreme braking conditions. Flush system with clean brake fluid and replace with a good grade of disc brake fluid. DOT 3 or DOT 4 fluids are acceptable. b) The simplest and most effective way to bleed your brakes is to use the gravity bleeding approach as follows: 1) With calipers installed, make sure all fittings are tight and master cylinder is topped off. 2) Open one bleeder screw at a time starting at the wheel farthest from the master cylinder and working your way back around the wheel closest to the master. With bleeder screw open, observe bleeder. At first the fluid will begin to escape with intermittent air bubbles. When the air bubbles stop and a steady flow of fluid is observed for several seconds, close the bleeder valve and move on to the next wheel. MAKE SURE TO KEEP A CLOSE WATCH OVER THE FLUID LEVEL INSIDE THE MASTER CYLINDER DURING THE BLEEDING PROCESS. NEVER LET THE RESERVOIR RUN DRY. ALWAYS KEEP IT AT LEAST 1 /3 FULL. 3) After bleeding both wheels and topping of the master cylinder make 20-30 applications of the brake pedal. If a hard pedal is experienced, no further bleeding is required. If pedal is spongy, repeat bleeding process until a hard pedal is achieved. 4) With all bleeding complete, there should be approximately 3 /4 to 1 of end play. 5) Power brake trucks will experience a drop off of the pedal when the engine is started. This is a normal condition that signifies the booster is working. 3
11) Parking Brake Adjustment a) Advance pistons of calipers so that clearance between pads and rotors is 1 /32-1 /16. Piston should be advanced using hydraulic system instead of parking brake levers. About 40 pumps of the pedal are required to extend the pistons to the correct clearance. IF PISTON HAS BEEN EXTENDED TOO FAR, TURN PISTON BACK INTO CALIPER. IF DESIRED, USE SPECIAL TOOL KD-2545 AVAILABLE AT MOST PARTS STORES. A PAIR OF NEEDLE NOSE PLIERS WILL ALSO WORK. b) Make sure the parking brake lever is in the full released position. c) Take up the slack in the parking brake cables by adjusting the nut on the threaded rod under the truck. Cables should be adjusted until they are taught but not enough to move the parking brake levers on the calipers when the parking brake handle is in the released position. d) Move the parking brake handle through its full travel several times. The parking brake should hold the truck from rolling but create no brake resistance when in the full released position. Make sure the brake lever on the calipers returns all the way when the parking brake handle is released. FINAL INSPECTION a) Once a hard pedal is achieved, all fittings and connections must be inspected to make sure there are no leaks. Also check the level in both reservoirs of the master cylinder and top off if needed. b) Put wheels back on the truck and turn wheel by hand to insure that the wheel spins freely and does not interfere with any brake components. c) When you are sure there are no interferences and the pedal is firm, torque the lug nuts and lower the truck back onto the ground. Test drive the truck and apply the brakes frequently to seat the pads. NOTE: DO NOT USE ANTI-SQUEAK ADHESIVE ON BACKS OF PADS. THIS WILL DE-GRADE THE PERFORMANCE OF THE CALIPER! DO NOT DRIVE IN TRAFFIC UNTIL THE BRAKES SAFELY STOP THE CAR A SAFE DISTANCE WITHOUT A SPONGY PEDAL FEEL! BRAKING TESTS SHOULD ALWAYS BE DONE IN A SAFE OPEN AREA!

How and why do I bench bleed a master cylinder? When installing or replacing a master cylinder, it is critical that all air is removed from the master cylinder. This can easily be done by bench bleeding the master cylinder prior to installation. Using the SSBC master cylinder bleeder kit (#0460): 1) Place your master cylinder in a vise by the ears (not body). Make sure it is level. 2) Attach a piece of clear plastic hose to the short end of one of the plastic nozzles. Do the same to the other hose and nozzle. 3) Clip the plastic bridge to the wall and push the ends of the hose through the holes so they are SUBMERGED in the reservoir on either side of the wall. 4) Press the tapered end of the nozzle FIRMLY into the cylinder port hole with a twisting motion. Repeat this procedure on the other port hole. 5) Fill the reservoir with CLEAN brake fluid recommended by the manufacturer. 6) Using full strokes, push the piston in, then release. Do this until ALL the air bubbles have disappeared from the clear plastic hose. (CAUTION-MASTER CYLINDER WILL NOT BLEED PROPERLY UNLESS HOSES ARE SUBMERGED IN BRAKE FLUID UNTIL THE BLEEDING PROCESS IS COMPLETED.) Now mount master cylinder and avoid brake fluid leaking out of front and rear ports during installation. Bleeding steps for Dual Port Master Cylinder If you have a master cylinder with dual port holes (4 port holes - 2 on each side), it is necessary to bleed both port sides of the master cylinder. If both sides of the master cylinder are not bled, there will be air trapped in the master cylinder and your brakes will not function properly. To bleed dual port master cylinders: 1) Follow steps 1-6 above on the side you will be hooking the brake lines to. Plug the other side. 2) Once the air bubbles are no longer visible in the plastic hose, open the bleeder screws in the supplied plugs and allow the mater cylinder to gravity bleed. DO NOT push the master cylinder piston in while the plugs are gravity bleeding. 3) When clear, steady streams of fluid are coming out of both bleeders, close and tighten the bleeders. Give the master cylinder piston several strokes, making sure there are still no bubbles present in the clear plastic tubes. 4) Remove the tubes and plastic fittings and mount the master cylinder on the vehicle being careful not to spill brake fluid on any painted surfaces.
