Nissan Maxima Service and Repair Manual: Brake fluid

Inspection

LEVEL CHECK

• Make sure that a brake fluid level in reservoir tank is between MAX and MIN lines as shown.
• Visually check around reservoir tank for fluid leakage.
• If the level is excessively low, check brake system for leaks.
• If brake warning lamp remains illuminated after parking brake pedal is released, check brake system for fluid leaks.

Drain and Refill

CAUTION:

• Refill with new brake fluid. Refer to MA-15, "FOR USA AND CANADA : Fluids and Lubricants" (for United States and Canada) or MA-16, "FOR MEXICO : Fluids and Lubricants" (for Mexico).
• Do not reuse drained brake fluid.
• Do not let brake fluid splash on the painted surfaces of the body. This might damage the paint. If brake fluid is splashed on painted areas, wash it away with water immediately.
• Before working, disconnect ABS actuator and electric unit (control unit) harness connector or battery negative terminal.

1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) harness connector or battery negative terminal.
2. Connect a vinyl tube to bleed valve.
3. Depress brake pedal, loosen bleed valve, and gradually remove brake fluid.

4. Make sure there is no foreign material in the reservoir tank, and refill with new brake fluid.
5. Rest foot on brake pedal. Loosen bleed valve. Slowly depress brake pedal until it stops. Tighten bleed valve. Release brake pedal. Repeat the process a few times, then pause to add new brake fluid to master cylinder. Continue until the new brake fluid flows out of bleed valve.

   Bleed the air out of the brake hydraulic system. Refer to BR-16, "Bleeding Brake System".
