Only extra-heavy duty fluid meeting DOT-3 specifications must be used. Using an inferior fluid will result in component damage and reduced braking capabilities.
See Figure 1
About once a month, the fluid level in the master cylinder should be checked.
- Park the car on a level surface, turn it OFF and raise the hood.
- Wipe off the master cylinder cover before you remove it, to prevent contaminating the fluid with dirt.
On most models, a see-through reservoir is used, eliminating the need to remove the cover.
- Two types of lids are used on these master cylinders. One cover is snapped into place on the master cylinder. To remove this type, just press up on the two tabs at the side of the cover, then tilt and remove it. Be careful not to damage the rubber seal under the cover. Another type of cylinder cover has a screw on cap, simply turn the cap to remove.
Don't leave the cover off of the master cylinder or the cap off of the brake fluid container any longer than necessary.
- The fluid level in each master cylinder reservoir should be 1 / 4 in. (6mm) below the lowest edge of the filler opening. If necessary, use fresh brake fluid to adjust the level.
It is normal for the master cylinder fluid level to drop as the brake linings wear about 1 / 8 in. (3mm) every 10,000 miles (16,100 km). If the fluid level is constantly low, the system should be checked for leaks.
- Carefully seat the seal into the cover, then snap the cover into place on the master cylinder. Be sure that all four snaps latch completely.
