A second base brake bleeding procedure is then required to remove any air remaining in the system.
Manual/Base System
- Remove reservoir filler caps and fill reservoir with proper brake fluid.
- If calipers or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws.
- Close each bleed screw as fluid starts to drip from them.

Master Cylinder
Except Caravan, Town & Country & Voyager
The cylinder body containing the primary and secondary pistons is made of aluminum. The removable fluid reservoir is made of nylon reinforced with glass fiber. The reservoir is the only serviceable component.
The fluid compartments of the nylon reservoir are interconnected to permit fluid level equalization. The equalization feature does not affect circuit separation in the event of a front or rear brake fault. The reservoir compartments will retain enough fluid to operate the functioning hydraulic circuit.
