  1. Clean the inside of the cylinder with a rag and inspect for scoring. If there is no serious damage, hone the cylinder just enough to remove deposits. Replace the cylinder if light honing does not remove the score marks. Wash all the parts in clean brake fluid before assembly.
  2.  
  3. Coat the new rubber parts with clean brake fluid and reassemble. Coat the piston with lithium soap based glycol grease.
