Brakes and Traction Control: Service Precautions

CAUTION:
^ All brake attaching fasteners are an important attaching part in that they could affect performance of vital parts and systems, and/or could result in major repair expense. They must be replaced with one of the same part number or with an equivalent part if replacement becomes necessary. Do not use replacement parts of lesser quality or substitute design. Torque values must be used as specified during reassembly to assure proper retention of these parts.
^ Do not use fluid which contains a petroleum base. Do not use a container which has been used for petroleum based fluids or a container which is wet with water. Petroleum based fluids will cause swelling and distortion of rubber parts in the hydraulic brake system. Water will mix with brake fluid, lowering the fluid boiling point. Keep all fluid containers capped to prevent contamination.
^ Improper brake fluid, mineral oil or water in the fluid may cause the brake fluid to boil or the rubber components in the hydraulic system to deteriorate.
^ If primary piston cups are swollen, then rubber parts have deteriorated. This deterioration may also be evidenced by swollen wheel cylinder piston cups on the drum brake wheels or master cylinder cover diaphragm.
^ If deterioration of rubber is evident, disassemble all hydraulic parts and wash with alcohol. Dry these parts with un-lubricated compressed air before assembly to keep alcohol out of the system. Replace all rubber parts in the system, including hoses.
^ When working on the brake mechanisms, check for fluid on the linings. If excessive fluid is found, replace the linings.
^ If master cylinder piston seals are satisfactory, check for leakage or excessive heat conditions. If condition is not found, drain fluid, flush with brake fluid, refill and bleed system.
