The master cylinder is an aluminum-plastic composite assembly with a external brake proportion valve. The cylinder has dual pressure chambers with a primary piston to supply hydraulic pressure to the front brakes and a secondary piston to pressurize the rear brakes. The cylinder is designed for a conventional front/rear split brake system with one outlet for both front brakes and one outlet for both rear brakes.
The master cylinder reservoir is attached to the master cylinder, which is located under the hood on the left side of the vehicle.
The reservoir must be kept properly filled to ensure adequate reserve fluid for the hydraulic system. However, because of expansion due to heat absorbed from the brakes and engine, the reservoir must not be overfilled.
Thoroughly clean the reservoir cap before removal to avoid getting dirt into the reservoir.
A properly maintained brake system should not need fluid to be added. Fluid level under normal conditions will go below the max fill mark on the reservoir due to brake pad wear. Topping off the reservoir is not recommended in this instance because the reservoir will be over filled when the brake pads are replaced.
