Why does it need brake fluid added?
1)--it wasn't filled enough in the beginning, and normal wear on the brake pads leaves more fluid in the caliper.
2)--it has a leak that needs to be fixed.
1)--how thick is the friction material on the brake pads. If that's real thin, renew the pads, clean the caliper slides, flush & renew the brake fluid.
2)--find the leak & fix it, then flush & renew the fluid.
Brake fluid is made to absorb humidity from the air. Moisture will get into the system, and it is better for the fluid to disperse through the fluid than puddle in the caliper and cause a problem. But...the moisture laden fluid will flash to vapor under the heat of emergency braking, giving you no brakes at all. Flush and renew the fluid every 2 years. Any brand of DOT4 brake fluid is the right stuff. The chemicals that make DOT4 fluid safe at higher temperatures than DOT3 also make it absorb moisture more readily.
