Use only heavy duty brake fluid meeting DOT 3 specifications from a clean, sealed container. Using any other type of fluid may result in severe brake system damage.
See Figures 1 through 7
It should be obvious how important the brake system is to safe operation of your vehicle. The brake fluid is key to the proper operation of your vehicle. Low levels of fluid indicate a need for service (there may be a leak in the system or the brake pads may just be worn and in need of replacement). In any case, the brake fluid level should be inspected at least during every oil change, but more often is desirable. Every time you open the hood is a good time to glance at the master cylinder reservoir.
- Make sure the vehicle is parked on a level surface, then raise the hood.
- Wipe off the master cylinder cover before you remove it, to prevent contaminating the fluid with dirt.
On some models, a see-through reservoir is used, eliminating the need of removing the cylinder cover.
- On early model vehicles, the cover is snapped into place on the master cylinder. To remove the cover, just press up on the two tabs on the side of the cover, tilt it, then remove it. Be careful not to damage the rubber seal under the cover.
- On later model vehicles, the master cylinder cap is a screw-on type. Simply unscrew the cap (and diaphragm, if equipped), and remove it from the reservoir.
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 or reach the marking shown in the reservoir. Use fresh brake fluid to adjust the level if necessary.
It is normal for the master cylinder fluid level to drop as the brake linings wear - 1 / 8 in. (3mm) drop about every 10,000 miles (16,100km). If the fluid level is constantly low, the system should be checked for leaks.
- Carefully seat the cover seal into the cover, then snap or screw the cover into place on the master cylinder. If equipped, with a snap-on lid, make sure that all four snaps latch completely.
