Inspection

1. Check conditions of tires and wheels. Damaged or worn wheels and tires can cause a pull, shudder,

vibration and a condition similar to sudden braking.

2. If noise occurs while braking, check suspension components. Bounce vehicle up and down several times

and check suspension or steering components for any looseness, wear or damage.

3. Check brake fluid level and condition.

a. If brake fluid level is low, check ABS control unit assembly, brake wheel cylinder, brake caliper, brake

line, brake master cylinder assembly and brake fluid reservoir, etc. for leakage.

b. If brake fluid is contaminated, drain an amount of fluid to check. Replace with new fluid as necessary.

HINT:
It is normal that brake fluid will become dark after being used for a period of time. Do not mistake this for
contamination.

CAUTION

 Use well-sealed brake fluid DOT4 or equivalent. DO NOT use oily solution, otherwise brake system seal

may be damaged.

 Brake fluid may damage paint surface. If brake fluid spills on paint surface, wash it off immediately with

water.

 DO NOT use gasoline, kerosene, alcohol, engine oil, transmission oil or any other fluid that contains

mineral oil to clean the system components. These kinds of fluid will damage rubber cover and seal.

 During servicing, make sure to clean grease or other foreign matter on the outer surface of brake caliper

assembly, brake lining, brake disc and wheel hub.

 When operating brake disc and brake caliper, be careful to prevent damaging brake disc and brake

caliper or scratching or cutting brake shoe linings.

ON-VEHICLE SERVICE

Brake Bleeding

HINT:
An assistant will be required to assist when bleeding brake system.

1. Fill the brake fluid reservoir with brake fluid to proper level.
2. Loosen the bleeder plug cap and connect a clear plastic hose to the bleeder plug. Submerge the end of

hose into the clear container filled with new brake fluid.

3. Have an assistant depress the brake pedal 3 to 4 times

repeatedly; depress and hold the brake pedal to a lower
position. Then loosen the bleeder plug, and rotate it at
least one turn.

4. Tighten the bleeder plug every time the brake pedal

moves down quickly. Then release the brake pedal.

WARNING

 When bleeding brake system, wear safety glasses.
 Be careful when bleeding air, as brake fluid at high pressure may spray out of bleeder plug.

CAUTION

 Before removing brake fluid reservoir, wipe it off to prevent dust and other foreign matter from dropping

into the brake fluid reservoir.

 Use fresh, clear and well-sealed brake fluid of specified type or equivalent.
 DO NOT allow brake fluid to adhere to any paint surface, such as vehicle body. If brake fluid leaks onto

any paint surface, immediately wash it off.

 During bleeding, do not depress brake pedal repeatedly at any time with bleeder plug opened.

Otherwise, the amount of air in system will increase, and further bleeding is needed.

 DO NOT drain brake fluid in brake fluid reservoir while bleeding brake system.

5. Repeat above steps, and bleed the brake lines of each wheel in the same manner in the order of rear left

wheel, front right wheel, rear right wheel and front left wheel, until all air are bled from the brake lines.
Empty sign: a stream of fresh brake fluid flows into the clear container without bubbles.
HINT:
During bleeding the brake system, make sure the brake
fluid level is always near the "MAX" mark. Check the
brake fluid level at all times during bleeding. Add brake
fluid as necessary.

6. Check and adjust the brake fluid level to the "MAX" mark.
7. Check brake pedal effect. If braking effect is improper or the pedal is spongy, air may still exist in the

system. Perform bleeding procedures again for brake system as necessary.

8. Have the vehicle tested to confirm that brake operates properly and pedal feel is correct.

Brake Fluid Replacement

1. Drain the brake fluid.

a. Start the engine and run it at idle.
b. Remove the filler cap of brake fluid reservoir assembly. Remove the bleeder plug cap and connect a

clear plastic hose to the bleeder plug, and submerge the end of hose into the clear container filled with
new brake fluid.

c. Loosen the bleeder plug, and depress the brake pedal

continuously until the brake fluid stops coming out.

2. Add brake fluid.

a. Tighten the bleeder plug after confirming that brake fluid is drained. Fill the brake fluid reservoir with

new brake fluid to the proper level.

3. Perform bleeding procedures.

a. After replacing with new brake fluid, make sure to bleed the brake system for normal operation.

See

page 26-12

for detail information about brake bleeding.

Brake Fluid Reservoir Assembly

On-vehicle Inspection

1. Check the brake fluid level warning switch.

a. Remove the brake fluid reservoir filler cap.
b. Disconnect the brake fluid level warning switch wire

harness connector.

c. Using ohm band of digital multimeter, check for

continuity between brake fluid level warning switch
terminals according to conditions shown in the table
below.
Standard Condition

HINT:

 There is a float in the fluid reservoir. The position of float changes according to increasing or decreasing

brake fluid level.

 If result is not as specified, replace brake fluid reservoir assembly.
d. Add brake fluid to the "MAX" mark.

Removal

1. Drain the brake fluid (

See page 26-13

).

2. Remove the brake fluid reservoir assembly.

a. Disconnect the brake fluid level warning switch

connector (arrow).

ENVIRONMENTAL PROTECTION

 Drained brake fluid should be well kept in a container. Never discard it at will.

CAUTION

 Wash off brake fluid immediately if it comes in contact with any paint surface.
