Precaution for Brake System

Warning:

Clean any dust from the front brake and the rear brake using a vacuum dust collector. Do not blow by compressed air.

• Use the correct brake fluid. Refer to Fluids and Lubricants.

• Do not reuse drained brake fluid.

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface.

• Always clean with new brake fluid when cleaning the master cylinder, brake caliper, and other components.

• Do not use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause improper operation.

• Always loosen the brake tube flare nut using a flare nut wrench.

• Tighten the brake tube flare nut to the specified torque using a flare nut crowfoot (A) and torque wrench (B).

  

• Always confirm the specified tightening torque when installing the brake pipes.

• Place the ignition switch in the OFF position and disconnect the ABS actuator and electric unit (control unit) harness connector or the battery negative terminal before performing the work.

• Always connect the battery terminal when moving the Nissan Sentra vehicle.

• Check that no brake fluid leakage is present after replacing the parts.

• Check for bends, cracks, and damage to the brake pedal. Adjust the brake pedal if it is outside the standard value.

• Burnish the brake contact surfaces after refinishing or replacing rotors, after replacing pads, after refinishing or replacing drums, after replacing shoes, or if a soft pedal occurs at very low mileage. Refer to Periodic Maintenance Operation.
