Reverse Brake Piston: Disassembly
- Using appropriate spring compressor, compress piston return springs and remove snap ring. Remove spring retainer and return springs. Position transmission with front opening facing upward.
- Place shop towels under case to prevent piston damage. Apply air pressure to case passages to remove reverse brake outer piston, reaction sleeve and reverse brake inner piston. See Figure. It may be necessary to use long hooks to remove sleeve and inner piston. Using screwdriver, pry manual valve lever shaft seals from case if replacement is required.
