3)   Draw out the brake fluid from master cylinder with syringe.

4)   Refill reservoir tank with recommended brake fluid.

Recommended brake fluid:

-  Avoid mixing different brands of brake fluid to prevent degrading the quality of the fluid.

-   Be careful not to allow dirt or dust to get into the reservoir tank.

NOTE:

-  Cover bleeder with waste cloth, when loosening it, to prevent brake fluid from being splashed over surrounding parts.

-   During bleeding operation, keep the brake reserve tank filled with brake fluid to eliminate entry of air.

-   Brake pedal operation must be very slow.

-   For convenience and safety, it is advisable to have two men working.

-  The amount of brake fluid required is approximately 500 m€ (16.9 US fl oz, 17.6 Imp fl oz) for total brake system.

6)   Instruct your co-worker to depress the brake pedal slowly two or three times and then hold it depressed.

7)   Loosen bleeder screw approximately 1/4 turn until a small amount of brake fluid drains into container, and then quickly tighten screw.

8)   Repeat steps 6) and 7) above until there are no air bubbles in drained brake fluid and new fluid flows through vinyl tube.

NOTE:

Add brake fluid as necessary while performing the air bleed operation, in order to prevent the tank from running short of brake fluid.

9)  After completing the bleeding operation, hold brake pedal depressed and tighten screw and install bleeder cap.

Tightening torque:

8 Nm (0.8 kgf-m, 5.8 ft-lb)

10)   Bleed air from each wheel cylinder by following the previous 5 steps.

11)   Depress brake pedal with a force of approximately 294 N (30 kgf, 66 lb) and hold it there for approximately 20 seconds. At this time check pedal to see if it makes any unusual movement. Visually inspect bleeder screws and brake pipe joints to make sure that there is no fluid leakage.

12)   Install wheels, and drive vehicle for a short distance between 2 to 3 km (1 to 2 miles) to make sure that brakes are operating properly.
