### Brake System Bleeding

NOTE: If vehicle is equipped with a Anti-Lock Brake System (ABS) refer to the service procedure later this section.

The purpose of bleeding the brakes is to expel air trapped in the hydraulic system. The system must be bled whenever the pedal feels spongy, indicating that air, which is compressible, has entered the system. It must also be bled whenever the system has been opened or repaired. You will need a helper for this job.

Never reuse brake fluid which has been bled from the system.

The usual sequence for bleeding is right rear (RR), left rear (LR), right front (RF), left front (LF). The service procedure is to bleed at the points farthest from the master cylinder assembly first. Follow this order when bleeding the brake system on your vehicle:

- 1982–88 200SX bleed in this order RR, LR, RF, LF wheels
- 1989–92 240SX bleed in this order LR, RR, LF, RF wheels
- 1982–85 Stanza bleed in this order RR, LF, LR, RF wheels
- 1986–92 Stanza, Stanza Wagon bleed in this order LR, RF, RR, LF wheels
