Brake Bleeding Procedures

- Brake Bleeding Procedures Brake System Bleeding

   

• 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.

• Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.

• Do not spill brake fluid on the vehicle, 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.

1.Make sure the brake fluid in the reservoir is at the MAX (upper) level line.

2.Have someone slowly pump the brake pedal several times, and then apply pressure.

3.Loosen the right-rear brake bleed screw (A) to allow air to escape from the system. Then tighten the bleed screw securely.[Front]

ABS System Bleeding This procedure should be followed to ensure adequate bleeding of air and filling of the ESC unit, brake lines and master cylinder with brake fluid.

1.Remove the reservoir cap and fill the brake reservoir with brake fluid.

   

• If there is any brake fluid on any painted surface, wash it off immediately.

• When pressure bleeding, do not depress the brake pedal.

• Recommended fluid........ DOT3 or DOT4
