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 a screwdriver, pry manual valve lever shaft seals from case if replacement is required.
