Checking Brake Fluid LevelNLBR0006+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.
+Release parking brake lever and see if brake warning lamp
goes off. If not, check brake system for leaks.
SBR389C
Checking Brake LineNLBR0007CAUTION:
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.
SBR419C
Changing Brake FluidNLBR0008CAUTION:
+Refill with new brake fluid“DOT 4”.
+Always keep fluid level higher than minimum line on res-
ervoir 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 minimum
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 and“Air
Bleeding Procedure”, CL-10.
Brake Burnishing ProcedureNLBR0036Burnish the brake contact surfaces according to the following pro-
cedure 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 sec-
onds.
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 burnish-
ing procedure.
NBR357
Bleeding Brake SystemNLBR0009CAUTION:
+Carefully monitor brake fluid level at master cylinder dur-
ing bleeding operation.
+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 OFF and dis-
connect ABS actuator connectors or battery ground cable.
SBR419C
+Bleed air in the following order.
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.

3. Check hoses for damage. If the hoses show cracks or damage,
replace the hose.
4. Insert the dot (coloured) mark hoses to the primary - and sec-
ondary inlet ports adapter. Then secure it with clamps.

5. Fill up reservoir tank with new brake fluid.
6. Plug all ports on master cylinder with fingers to prevent air
suction while releasing brake pedal.
7. Have driver depress brake pedal slowly several times until no
air comes out of master cylinder.
8. Fit brake lines to master cylinder.
9. Tighten flare nuts.
