Master Cylinders

Print

All models utilize a brake master cylinder and also a clutch master cylinder, if the vehicle has a manual transaxle. Both are located at the brake booster unit at the driver's side firewall.

FLUID RECOMMENDATIONS



Use only Heavy Duty Brake fluid meeting DOT 3 or SAE J1703 specifications.

The fluid in the brake and/or clutch master cylinders should be checked every 6 months or 6,000 miles (9,600 km).

Check the fluid level on the side of the reservoir. If fluid is required, clean the outside area of the cap, if necessary, then remove the filler cap and gasket from the master cylinder. Fill the reservoir to the Max line on the reservoir. Install the filler cap, making sure the gasket is properly seated in the cap.

CAUTION
To avoid personal injury, make sure no dirt or foreign material gets into the master cylinder when removing the cap. This could potentially cause brake failure.


WARNING
It is normal for the fluid level to fall as the disc brake pads wear. However, if the master cylinder requires filling frequently, you should check the system for leaks in the hoses, master cylinder, or wheel cylinders. Brake fluid dissolves paint. It also absorbs moisture from the air; never leave a container or the master cylinder or the clutch cylinder uncovered any longer than necessary. The clutch master cylinder uses the same fluid as the brakes, and should be checked at the same time as the brake master cylinder.
