-===== Cleaning The Master Cylinder ===== 
- 
-  * For use with DOT 5 brake fluid: Always clean brake system rubber parts by washing in denatured alcohol or DOT 5 brake fluid. Do not use mineral base cleaning solvents such as gasoline or paint thinner. These cause deterioration of non-metallic parts which would continue to deteriorate after assembly, possibly resulting in component failure. ((HD Service Bulletin #M-785 dated June 10, 1980))
