BRAKE FLUID, CHECKING DEPENDING ON BRAKE PAD WEAR

Please observe the following

Delivery Inspection

Scheme 8

1. Fluid level must be at MAX mark

Note. To prevent the brake fluid from overflowing from the reservoir, the level must not be over the MAX mark.

Inspection Service

When driving, fluid level drops slightly from use and automatic brake pad adjustment.

Always check fluid level in conjunction with brake pad wear

1. When brake pads are new or if there is still enough brake lining left, the brake fluid level must be between MIN and MAX marks.
2. With brake fluid at MIN mark or slightly above, topping off brake fluid is not necessary when wear limit of brake pads has been almost reached.

Special tools and workshop equipment required

Scheme 9

Scheme 10

Open brake fluid reservoir.

Open bleeder screw on right rear brake caliper.

Prepare a suitable bleeder bottle to collect the used brake fluid.

Pump up brake fluid by pressing brake pedal with engine running until fluid reaches the level of the hose connector -arrow- on the reservoir.

Scheme 11
