Usage:
1. Move the machine until the valve stem opening in the tire rim is in alignment with the top anchor pin in the brake head assembly.
2. For the front wheel brake linings, lift the bucket and put tooling (A) in position under the lift arm for support. Move the control lever and lower the weight of the lift arms and bucket on tooling (A) as shown.
3. Open the bleed valves with tool (B) to release any pressure on the brake pistons. Push the pistons into the head assembly to remove the pressure on the brake linings.
| NOTICE |
|---|
To prevent damage to pistons and seals, do not make an application of the brakes when the brake linings are removed. The pistons must not move out of their bores as the brake linings are removed. If the pistons and seals move out of their bores, the brake head assembly must be removed to install the pistons. |
4. Loosen bolts (1) that hold the anchor pins in position.
5. If necessary use tool (C) to pull the anchor pins out of the head assembly .75 in. (19.1 mm) approximately.
6. Remove the brake linings.
Install Wheel Brake Linings
1. Push the brake pistons into the brake head assembly. This gives clearance for the new brake linings.
2. Install brake linings (1) in the brake head assembly.
3. Push anchor pins (3) into the brake head assembly.
4. Make sure there is .010 in. (.25 mm) or more distance between the anchor pins and wheel disc. Tighten bolts (2) to hold the anchor pins.
5. Use tool (B) and remove (bleed) the air from the hydraulic brake system. See HYDRAULIC BRAKE SYSTEM SERVICING in TESTING AND ADJUSTING.
6. For the front brake linings, remove tooling (A) and lower the bucket to the ground.
