How to Remove the Rear Drum Brakes on Vehiclesby Contributing Writer
The rear brakes on a Vehicles pickup consist of three main parts, the brake drum, the brake shoes and the wheel cylinder. The brake drum is attached to the rear axle and rotates along with the rear wheels and tires. A pair of brake shoes sits inside each brake drum, one facing forward and one facing rearward. The wheel cylinder is bolted to the brake backing plate and sits in between the two brake shoes. When the driver presses down on the brake pedal, hydraulic pressure is sent from the master cylinder to the wheel cylinder. A piston on each side of the wheel cylinder, presses the brake shoes against the brake drum, which in turn slows down the Vehicles. The drum brakes must be disassembled to replace the rear axle or wheel bearings.

How to Remove the Rear Drum Brakes From a Toyota Tacoma
Park the Toyota Tacoma on a level paved or concrete surface.
Place a wheel chock in front of one of the front tires.
Break the lug nuts loose on both rear wheels with the breaking bar and a 21-mm socket.
Lift the rear axle on one side of the Tacoma and place a jack stand under the rear axle on that side. Repeat this step for the other side so the rear axle is suspended.
Remove the lug nuts and both tires.
Strike the flat hub face of the drum near the edge to loosen it from the hub. If it is stubborn, spray a little WD-40 into the small screw holes located near the hub. Thread in the two 8 by 1.25 mm bolts and tighten them alternately with the ratchet and a socket to pull the drum away from the hub.
Remove the drum and remove the bolts. Remove the other drum in the same manner.
Start to remove the left side brakes first. Using the brake spring pliers, remove the upper return spring connecting the two shoes together.
Remove the rear shoe (toward the rear of the Tacoma). Hold down the spring by holding the head of the pin on the back of the backing plate with a finger. Use the brake shoe retaining spring tool to twist the spring free from the hold-down pin. Remove the shoe and the anchor spring at the bottom.
Remove the front shoe hold down spring in the same manner. Disconnect the parking brake cable from the bell crank. Remove the E-clip, the automatic adjuster lever. Spread and remove the C washer with the flathead screwdriver, and remove the parking brake lever from the shoe.
Remove the front shoe with the strut intact.
Disconnect the other parking brake cable.
Disconnect the adjuster lever spring and remove the adjuster from the shoe.
To replace, reverse the order. Keep the right side intact to help you put the brakes and hardware back in the same manner they were removed.
Repeat the procedure for the right side, using the left as reference.
