Installation of Emergency Brake Shoes on a 1999 Chevy Silverado

The emergency brakes shoes on the 1999 Chevrolet Silverado are mounted to the top of the rear brake shoes. The emergency brake shoes are secured inside the brake actuator that sits on top of hub assembly. Once the emergency brake cable is engaged, the brake shoes compress to the sides of the brake rotor to prevent the rear wheels from turning. The emergency brake shoe cable and the emergency brake shoe set screw must be removed before the brake shoes can be removed and replaced.

Instructions

1

Park the 1999 Chevrolet Silverado truck on a flat surface. Turn the engine off, but do not set the emergency brakes. Place the wheel chocks in front of the front wheels and behind the front wheels.

2

Loosen the driver side rear and passenger side rear lug nuts from the rear wheels with a tire tool.

3

Jack up the rear of the Silverado and place the jack stands under both rear designated jacking points. Slowly lower the jack until the full weight of the truck is sitting on the jack stands. Leave the jack in place.

4

Finish removing the lug nuts from both rear wheels with the lug wrench. Pull both rear wheels off and place them near each work area along with the lug nuts. Move back to the driver side rear to begin the emergency brake shoe replacement.

5

Loosen and remove the two caliper mounting bolts from the back side of the caliper with a ratchet and a socket. Pull the bolts out of the caliper and place them near the work area. Slide the flat tip of a flathead screwdriver through the opening on the front of the brake caliper so that the tip of the screwdriver is between the rear brake pad and the brake caliper. Pry against the brake shoe with the screwdriver until the caliper is loose.

6

Remove the screwdriver and lay it near the work area. Pull the caliper straight up off of the brake rotor with your hands. Hang the brake rotor with the brake pads to one of the suspension components with a bungee cord. Loosen and remove the bolts from the caliper mounting bracket that the brake caliper was secured to. Pull the bolts out of the bracket and lay them near the work area. Pull the caliper mounting bracket off of the hub and place it near the work area also.

7

Slide the brake rotor straight off of the wheel hub and the emergency brake shoe drum. Place the rotor on the ground near the work area. Slide the brake drum off of the top of the emergency brake shoes. Use a rubber mallet if necessary to tap the drum off of the brake shoes. Once the drum is off, the emergency brake shoes can be accessed.

8

Locate the parking brake shoe assembly at the top of the wheel hub. Also locate the set screw and the mounting clip on the bottom of the parking brake assembly. Completely remove the set screw from the assembly with a screwdriver. Pry the clip off of the assembly with the screwdriver. Place the screw and the clip near the work area. Pull the parking brakes straight up out of the assembly, which is the brake shoe actuator, and around the axle flange. Place the old parking brake shoes on the ground away from the work area.

9

Position the new brake shoes around the axle flange and into the brake actuator assembly. Reconnect the set screw and the mounting clip with the screwdriver. Ensure that both of the emergency brake shoes are installed correctly inside of the brake actuator as the old brake shoes were. Locate the brake shoe adjuster bolt at the top of the brake shoe assembly. Turn the adjuster bolt clockwise to separate the brake shoes enough for the drum to fit over the shoes.

10

Slide the drum over the brake shoes and adjust the brake shoes from the adjuster until the brake shoes have a slight drag against the surface of the brake drum. Once the brake shoes begin to drag against the drum, back the brake shoes off about one-eighth inch away from the surface of the brake drum. Once the drum is over the brake shoes, the adjuster can be accessed from the back side of the brake shoes.

11

Slide the brake rotor straight onto the hub and in front of the drum. Re-install the caliper mounting bracket around the brake rotor with the bracket bolts. Tighten the bracket bolts down tight with the ratchet and socket. Torque the bracket bolts down to 100 foot-pounds with a torque wrench and a socket. Un-hang the brake caliper from the suspension and remove the bungee cord. Slide the brake caliper over the rotor and onto the bracket. Screw the two rear caliper bolts into the back of the caliper, and tighten them down tight with the ratchet and socket. Torque both caliper mounting bolts down to 50 foot-pounds with the torque wrench and a socket.

12

Slide the wheel onto the hub and screw the lug nuts on tightly. Move to the passenger side rear brakes and repeat the same process as outlined above to replace the emergency brake shoes. Slide the passenger side wheel on and screw the lug nuts on tightly.

13

Jack the rear of the Silverado up and remove the jack stands. Lower the truck to the ground and remove the jack. Finish tightening all of the lug nuts on the rear wheels with the tire tool.

14

Check the operation of the emergency brake by setting the emergency brake and cranking the engine. Put one foot on the brake pedal and put the gear shift in drive. Slowly release the brake pedal, and the emergency brake shoes should prevent the truck from moving. Turn the engine off. Remove the wheel chocks.
