UNDERDRIVE Brake & Accumulator: Inspection
- Clean all parts (except discs) with solvent. Dry parts using compressed air. Inspect discs and plates for wear or burnt areas. If discs are peeled or discolored, replace discs as necessary.
- Inspect underdrive brake piston. Ensure check ball is free by shaking piston. Ensure valve does not leak by applying low pressure compressed air to small hole in piston.
NOTE:
New discs must be soaked in ATF at least 15 minutes prior to reassembly.
