這是為什麽要換，如果自己能換dot3很便宜。一般5,6年或10萬麥應該換一下

Exposure to air swiftly contaminates brake fluid: The oxygen in the air oxidizes it and lowers its boiling point. Brake fluid also has an affinity for moisture, and the water vapor in the air can combine with the brake fluid, lowering its boiling point and, in cold weather, forming ice crystals that make braking difficult. Adding fluid contaminated with water vapor to your brake system can rust the system and create acids that etch your wheel cylinders and master cylinder and foul your brakes, causing them to work poorly — or not at all. It can also destroy vital parts of ABS and other expensive braking systems.

• 嗯，謝謝，我也看過類似的描述，我可能會自己換的。 -yddad- ♂ (0 bytes) () 04/03/2014 postreply 09:27:39
