Toyota Truck Park Brake Bellcrank Repair


Filed Under (Toyota Manuals) by admin on 01-10-2011

Toyota trucks including Tacoma, T100 and Tundra with rear drum brakes use a bellcrank apparatus through the brake backing plate as part of the parking brake system. These bellcranks, made of aluminum and steel are known for seizing up. The photo below (fig.1) shows the tell tale sign of a seized bellcrank, this one being on the right side. The sagging cable that runs across the differential is a warning. If you notice this you need to check the action of the bellcranks before using the parking brake further. Using the parking brake with this condition can cause damage to the brake shoes and drum.
2 Removing Toyota Drums If you have never removed your drums, you will likely find that they are stuck in place. Rust tends to build up between the drum and hub flange making them difficult to remove.

Relationship Between Tire Characteristics and Vehicle Pulling to One Side When radial tires are rotating, they have the characteristic of generating force in the lateral direction between the tire and the road surface. This lateral force is comprised of two factors: S Ply-steer, which changes direction according to the rotation direction of the tires.
S Conicity, which is generated in a fixed direction regardless of the tire rotation direction. If these lateral forces are too strong, vehicle pulling will occur. A. Ply-Steer Lateral force due to ply-steer is produced by the construction of the belts inside the tire tread. With radial tires, the wire of the belt is slanted as shown in the illustration below. Thus, it is in the lateral direction that tire tread easily changes shape (stretches), and lateral force is generated between the tire and the road surface in the lateral direction.

Use fender seat and floor covers to keep the vehicle clean and prevent damage.2. During disassembly, keep parts in order to facilitate re- assembly. 3. Observe the following: (a) Before performing electrical work, disconnect the cable from the battery terminal. (b) If it is necessary to disconnect the battery for inspec- tion or , always disconnect the cable from the negative ( —) terminal which is grounded to the vehi- cle body. (c) To prevent damage to the battery terminal post, loosen the terminal nut and raise the cable straight up without twisting it or prying it. (d) Clean the battery terminal posts and cable terminals with a shop rag. Do not scrape them with a file or such.

(e) Install the cable terminal to the battery post with the nut loose, and tighten the nut after installation. Do not use a hammer or such to tap the terminal on- to the post. (f ) Be sure the cover for the positive ( + ) terminal is pro- perly in place. Check hose and wiring connectors to make sure that tir
are secure and correct
