Checking Brake Fluid Level

●

Check fluid level in reservoir tank. It should be between Max.
and Min. lines on reservoir tank.

●

If fluid level is extremely low, check brake system for leaks.

●

If brake warning lamp comes on and fluid level is above
“MIN” mark, check brake fluid level switch and parking brake
switch.

Checking Brake Line

CAUTION:

If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration

or other damage. Replace any damaged parts.

2. Check for oil leakage by fully depressing brake pedal while

engine is running.

Changing Brake Fluid

CAUTION:

●

Refill with new brake fluid “DOT 4”.

●

Always keep fluid level higher than minimum line on
reservoir tank.

●

Never reuse drained brake fluid.

●

Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.

1. Clean inside of reservoir tank, and refill with new brake fluid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake fluid from each air bleeder valve by depressing

brake pedal while keeping reservoir level higher than mini-
mum line by adding new brake fluid.

4. Repeat until new brake fluid comes out of each air bleeder

valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to “Bleeding Brake System”, BR-8.

Brake Burnishing Procedure

Burnish the brake contact surfaces according to the following
procedure after refinishing or replacing rotors, after replacing
pads, or if a soft pedal occurs at very low mileage.

CAUTION:

Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31

MPH).

2. Use medium brake pedal/foot effort to bring the vehicle to a

complete stop from 50 km/h (31 MPH). Adjust brake pedal/
foot pressure such that vehicle stopping time equals 3 to 5
seconds.

3. To cool the brake system, drive the vehicle at 50 km/h (31

MPH) for 1 minute without stopping.

4. Repeat steps 1 to 3, 10 times or more to complete the bur-

nishing procedure.

Bleeding Brake System

CAUTION:

●

Carefully monitor brake fluid level at master cylinder
during bleeding operation.

●

If master cylinder is suspected to have air inside, bleed
air from master cylinder first. Refer to “Installation”,
“MASTER CYLINDER”, BR-17.

●

Fill reservoir with new brake fluid “DOT 4”. Make sure it
is full at all times while bleeding air out of system.

●

Place a container under master cylinder to avoid spillage
of brake fluid.

●

For models with ABS, turn ignition switch to the OFF
position and disconnect ABS fuse or battery cable.

●

Bleed air in the following order:

RHD models

Left rear brake

Right front brake

Right rear brake

Left

front brake

LHD models

Right rear brake

Left front brake

Left rear brake

Right

front brake.

1. Connect a transparent vinyl tube to air bleeder valve.
2. Fully depress brake pedal several times.
3. With brake pedal depressed, open air bleeder valve to

release air.

4. Close air bleeder valve.
5. Release brake pedal slowly.
6. Repeat steps 2. through 5. until clear brake fluid comes out

of air bleeder valve.

7. Tighten air bleeder valve.
