Brake System Bleeding

WARNING: This page is about a different variant/trim than selected.

CAUTION:

Do not reuse the drained fluid.
Always use genuine DOT3/DOT4 brake fluid.
Using a non-genuine DOT3/DOT4 brake fluid can cause corrosion and decrease the life of the system.
Avoid contaminating the brake fluid by keeping it away from dirt or other foreign matters.
Do not spill brake fluid on the vehicle as it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water.
The reservoir on the master cylinder must be at the MAX (upper) level mark at the start of bleeding procedure and checked after bleeding each brake caliper. Add fluid as required.

Make sure that the brake fluid in the reservoir is filled up to the MAX (upper) level line.
Have someone slowly pump the brake pedal several times, and then apply pressure.
Loosen the rear right-hand side brake bleed screw (A) to allow air to escape from the system. Then tighten the bleed screw securely.
