Usage:
start by:
a) remove brake master cylinder actuators
1. Remove the cap from the main brake fluid reservoir. Remove tube assembly (1) from the machine and drain the reservoir.
2. Remove tube assembly (3) from the machine.
3. Remove the cap from master cylinder (2). Disconnect brake line (4) and drain the master cylinder.
4. Remove the bolts and nuts that hold master cylinder (2) in position and remove the master cylinder.
Install Brake Master Cylinders
1. Install the cap on master cylinder (1) and put it in position on the machine. Install the bolts and nuts that hold it.
2. Connect brake line (2) to the master cylinder.
3. Install the tube assembly that connects the two master cylinders.
4. Install the tube assembly that connects the brake fluid reservoir to the master cylinders.

a) install brake master cylinder actuators
b) use tool (A) and remove (bleed) the air from the brake system (See HYDRAULIC BRAKE SYSTEM SERVICING in TESTING AND ADJUSTING)
Disassemble Brake Master Cylinders
start by:
a) remove brake master cylinders
1. Remove boot (2) from cylinder assembly (3). Remove retainer (1) from boot (2).
2. Remove lockwire (5), plate (6), piston assembly (7), cup (8) and spring assembly (9) from the cylinder assembly.
3. Remove fitting (4), the plug assembly and gasket from the cylinder assembly.
NOTE: A master cylinder rebuild kit is available. The kit includes a gasket, boot, seal, cup, piston assembly and lockwire. When the master cylinder is disassembled for service, always install a repair kit.
Assemble Brake Master Cylinders
NOTE: When the hydraulic brake system is serviced use caution to prevent introduction of foreign material into the brake fluid. Damaged or worn rubber parts are an indication of other fluids in the brake system. Flush and clean the system with denatured alcohol or clean brake fluid.
1. Put clean brake fluid on the inside parts of the master cylinder at assembly.
2. Inspect the bore in the master cylinder. Use a brake cylinder hone to remove any rough areas or corrosion in the master cylinder bore. If the cylinder bore has deep scratches a replacement of the master cylinder is needed.
3. Make sure the master cylinder bore is clean.
4. Install the gasket and plug assembly (1) in cylinder assembly (2).
5. Install spring (7) as shown. Install cup (6) with the open end toward spring (7).
6. Install piston assembly (5) as shown. Install plate (4) and lockwire (3).
| NOTICE |
|---|
Make sure lockwire (3) is fitted correctly in the groove of the master cylinder and piston assembly (5) returns against plate (4). |
7. Install the retainer in boot (8) and install the boot on cylinder assembly (1).
