How to Change Drum Brakes on Vehiclesby Contributing Writer; Updated June 12, 2017
One of the most vital systems on your Vehicles is its brakes. Failure to maintain the brakes on your Vehicles can greatly impact your safety as well as others on the road. Like many cars, the brakes used on the Vehicles rear wheels are drum brakes. This is a braking system where the brake pads are located inside a drum and push out against the drum when the brakes are engaged. You can change the drum brakes yourself with the right tools and knowledge.

Loosen the lug nuts on the rear wheels of your Neon with a lug wrench, but do not remove them from the studs. Raise the rear of the car until the tires are off the ground several inches, using a jack, then place a set of jack stands under the rear suspension to support the car.
Remove the lug nuts from the wheel studs and set them aside. Pull the tires off the car and set them off to one side for now.
Locate the inspection hole in the brake drum backing plate from the back side. Insert a small flat screwdriver into the hole and lift the adjuster tang slightly, then slide a brake spoon into the hole and turn the adjuster down, pulling the brake shoes away from the drum.
Grasp the drum with both hands and pull it straight off the brake shoes. Install the new drum, sliding it over the shoes and wheel studs. Push it all the way on until it bottoms out on the wheel hub and will not go any farther.
Turn the brake adjuster with the brake spoon until the shoes just start to drag on the new drum when you rotate it. Move to the opposite side and repeat the process.
Install the wheels on the car, followed by the lug nuts. Tighten the lug nuts with a lug wrench. Raise the car off the jack stands with a jack. Remove the jack stands from under the car and lower the jack , setting the car on the ground.
Tighten the lug nuts with the weight on the tires. After several days of normal driving, recheck the lug nuts to ensure they have not loosened up.

Park the Civic on a firm, flat surface. Engage the emergency brake and shift the car into "Park" if it's an automatic or in second gear if it's a stick shift.
Loosen the lug nuts on the rear wheels but do not remove them.
Raise the rear of the Civic with a jack and place jack stands underneath the outer frame. Slowly lower the car onto the jack stands.
Remove the lug nuts from the rear wheels with a lug nut wrench and take the tires off of the car. Work on one side of the car from this point forward.
Screw two 8 mm bolts into the holes on the front of the brake drum. Alternate turning each bolt two revolutions at a time until the brake drum comes off of the wheel hub.
Clean the brake drum and wheel hub with brake wash. Wear safety goggles and gloves and avoid direct contact with the dirt from the brakes as it may contain asbestos.
Disconnect the springs that hold the brake pads onto the wheel hub. Start with the bottom spring: press down on the spring and turn the pin that holds the shoes in place with a screwdriver and a pair of needle-nose pliers.
Remove the front brake shoe from the wheel hub. Disconnect the rear brake pad from the parking brake cable.
Remove the U-clip that connects the parking brake arm to the brake shoe by prying it off with the needle-nose pliers. If the hardware is too damaged to use the pliers on it, grind it off with a Dremel drill but do not grind down the pin.
Clean the wheel hub with brake wash. Apply brake grease to the locations on the wheel hub where the brake shoes make contact.
Slide the new brake pads into position on the wheel hub.
Reassemble the brake by reversing the process that you used to disassemble it. Repeat this procedure on the wheel on the other side of the car.
Remount the tires onto the wheel hubs then tighten the lug nuts with the lug nut wrench.
Raise the Civic off of the jack stands with the jack, remove the stands then slowly lower the car to the ground.

Losen the lug nuts on the Tahoe's rear wheels without removing them yet. Then raise the Tahoe's rear end on jack stands. Block the front wheels and remove both of the rear wheels. Release the parking brake.
Remove the brake drum, cutting off the pressed metal washers with a strong cutting tool. If the drum won't come off because the drum shoes have worn into the drum, retract the shoes by removing the access plug from the backing plate. Push the lever off the adjuster star wheel with a small screwdriver and turn the star wheel with another screwdriver.
Clean off the entire assembly with brake system cleaner, using a drain pan to catch the residue. Never blow away brake dust with compressed air.
Detach the spring from the adjuster level from within the drum by gripping it with pliers. Then pull out the retractor spring from the hole in each drum shoe.
Remove the trailing shoe and adjuster lever. Remove the adjuster screw assembly. Pull away the retractor spring and remove the leading shoe. Disconnect the trailing shoe from the parking brake lever.
Clean off the backing plate and lightly lubricate its shoe contact areas with high-temperature grease. Clean the adjuster screw assembly and lubricate the threads and socket end.
Inspect the condition of the drum itself. If there are any cracks, score marks, deep scratches or discolored areas that can't be removed with an Emory cloth, have the drum resurfaced at an automotive machine shop.
Attach the new trailing shoe to the parking brake lever, position it on the backing plate and install the retractor spring's end into its hole. Re-install the adjuster screw assembly, making sure it engages with the leading shoe. Lubricate and install the adjuster level on the trailing shoe.
Place the trailing shoe on the backing plate, making sure it properly engages with the adjuster screw assembly, and insert the retractor spring into its hole within the trailing shoe. Place the actuator spring within its hole in the leading shoe, stretch the spring and connect it to the adjuster level.
Install the drum back on the Tahoe. Turn the adjuster screw's star wheel until the drum slips over the shoes without rubbing them. Reconnect the wheels once the brakes are changed on both sides and lower the vehicle.

Slide the brake drums off of the rear brake shoes. If the drums are stuck, a few sharp blows with a hammer will break them free of any corrosion around the rear hub. Clean the brake shoes with brake parts cleaner to remove the dust from the brake system. The dust in the brake system should never be removed with compressed air. It is harmful to breath the dust created by car brake systems.
Remove the return springs that attached to the pivot pin at the top of the brake system using a return spring tool, from the set, to pry them over the pivot pin. Use a screwdriver to pry the spring from the lower edge of the self-adjuster arm and remove the rod that attaches the adjuster arm to the pivot pin. Remove the parking brake strut that is located below the wheel cylinder and connects the parking brake lever on one side to the brake shoe on the other side of the set.
Pull the lower edges of the brake shoes apart and allow the self adjuster to drop out of the shoes. Remove the self adjuster spring from the lower ends of the shoes. Remove the hold-down springs using the hold-down spring tool from the set. Pull the brake shoes from the backing plate. Clean and lubricate the backing plate using brake parts cleaner and silicon brake grease.
Install the parking brake lever from the old shoes onto the new shoes. Position the new shoes onto the backing plate and attach them to the backing plate with the hold down springs. Slip the parking brake strut into place between the lever and the shoes. Place the adjuster rod onto the adjuster lever and pivot pin, and attach the shoes to the pivot pin using the return springs.
Install the spring on the lower edge of the adjuster lever. Install the lower spring on the lower ends of the brake shoes. Pull the brake shoes apart and slip the self adjuster into place between the lower ends of the shoes. Slide the drum onto the shoes to check the fit. Adjust the shoes by rotating the self adjuster until the drum just fits onto the shoes.

Jack the axle up until the wheel is off the ground, then place a jack stand under the axle for added safety. Remove the lug nuts by turning them counterclockwise with the lug wrench, and lift the wheel off to gain access to the brake system.
Remove the drum from the brake system. It can be stubborn; if so, try hitting the edge of the drum with a sharp blow from a hammer, which will free the drum of any rust that has built up around the axle.
Remove the old shoes by removing the return down springs that attach the shoes to the anchor pin at the top of the assembly. This will allow the self-adjuster and parking brake spreader bar to fall free. Remove the primary and secondary shoes by releasing the hold-down springs attaching them to the backing plate. The secondary shoe is attached to the parking brake lever by a U-shaped clip; remove this clip.
Clean the hardware and backing plate with brake parts cleaner, and let it dry completely. From here on, pay attention to cleanliness. Avoid contaminating the shoes with dirt and grease, which can cause groaning and shudder of the brakes.
Lubricate the contact points, the three raised areas on each side of the backing plate, with brake grease.
Begin installing the new secondary shoe, the longer of the two shoes. It goes on the side of the assembly closest to the rear of the vehicle. Attach the shoe to the parking brake lever, then attach it to the backing plate with a hold-down spring.
Install the primary shoe to the backing plate with a hold-down spring. Make sure both shoes are positioned on the contact points of the backing plate and lined up on the anchor pin.
Install the parking brake spreader bar, self-adjuster cable and return springs. The parking brake spreader goes between the two shoes, at the top, and attaches the primary shoe to the parking brake lever. The loop on the adjuster cable slips over the anchor pin and is held in place by the return springs.
Install the self-adjuster return spring in the lower holes of the shoes, and slip the self-adjuster into place by spreading the shoes slightly. Install the star wheel side first, then slip the long side into place on the shoe.
Install the drum, and check the brakes for adjustment. Rotate the star wheel until the shoes are adjusted to fit the drum. There should be a slight drag when you rotate the drum. You've attained the proper fit when the wheel rotates about one turn before stopping when you spin it.
Reinstall the wheel by tightening the lug nuts in a star pattern, and lower the car to the ground. Check the tightness of the lug nuts, then test-drive the car.
