may result in a harmful chemical reaction, 
leading to poor brake performance.

• When refilling, be careful that water does 

not enter the brake fluid reservoir. Water 
will significantly lower the boiling point of 
the brake fluid and could cause vapor lock.

CAUTION:

INTRODUCTION

WARNING

EWA14100

Disc brake components rarely require disas-
sembly. Therefore, always follow these pre-
ventive measures:
• Never disassemble brake components un-

less absolutely necessary.

• If any connection on the hydraulic brake 

system is disconnected, the entire brake 
system must be disassembled, drained, 
cleaned, properly filled, and bled after reas-
sembly.

• Never use solvents on internal brake com-

ponents.

• Use only clean or new brake fluid for clean-

ing brake components.

• Brake fluid may damage painted surfaces 

and plastic parts. Therefore, always clean 
up any spilt brake fluid immediately.

• Avoid brake fluid coming into contact with 

the eyes as it can cause serious injury.

• FIRST AID FOR BRAKE FLUID ENTERING 

THE EYES:

• Flush with water for 15 minutes and get im-

mediate medical attention.

3. Measure:

• Brake disc deflection

Out of specification 

 Correct the brake disc 

deflection or replace the brake disc.
Refer to “CHECKING THE FRONT BRAKE

4. Measure:

• Brake disc thickness

Measure the brake disc thickness at a few dif-
ferent locations.
Out of specification 

 Replace.

Refer to “CHECKING THE FRONT BRAKE

the brake fluid and could cause vapor lock.

CAUTION:

ECA13540

Brake fluid may damage painted surfaces 
and plastic parts. Therefore, always clean up 
any spilt brake fluid immediately.

5. Bleed:

• Brake system

Refer to “BLEEDING THE HYDRAULIC 
BRAKE SYSTEM” on page 3-22.

6. Check:

• Brake fluid level

Below the minimum level mark “a” 

 Add the 

recommended brake fluid to the proper level.
Refer to “CHECKING THE BRAKE FLUID 
LEVEL” on page 3-20.

7. Check:

• Brake pedal operation

Soft or spongy feeling 

 Bleed the brake sys-

tem.
Refer to “BLEEDING THE HYDRAULIC 
BRAKE SYSTEM” on page 3-22.

NOTE:

Before removing the rear brake master cylinder, 
drain the brake fluid from the entire brake sys-
tem.

1. Remove:

• Rear brake hose union bolt “1”
• Copper washers “2”
• Rear brake hose “3”

NOTE:

To collect any remaining brake fluid, place a 
container under the master cylinder and the end 
of the brake hose.

ASSEMBLING THE REAR BRAKE MASTER 
CYLINDER

WARNING

EWA13520

• Before installation, all internal brake com-

ponents should be cleaned and lubricated 
with clean or new brake fluid.

• Never use solvents on internal brake com-

ponents.

INSTALLING THE REAR BRAKE MASTER 
CYLINDER

1. Install:

• Copper washers “1” 
• Rear brake hose “2”
• Rear brake hose union bolt “3”

WARNING

EWA13530

Proper brake hose routing is essential to in-
sure safe vehicle operation. Refer to “CABLE 
ROUTING” on page 2-45.

CAUTION:

EC1D71009

When installing the brake hose onto the 
brake master cylinder, make sure the brake 
pipe touches the projection “a” on the brake 
caliper bracket as shown.

2. Fill:

• Brake fluid reservoir

(with the specified amount of the recom-
mended brake fluid)

WARNING

EWA13090

• Use only the designated brake fluid. Other 

brake fluids may cause the rubber seals to 
deteriorate, causing leakage and poor 
brake performance.

• Refill with the same type of brake fluid that 

is already in the system. Mixing brake fluids 
may result in a harmful chemical reaction, 
leading to poor brake performance.

• When refilling, be careful that water does 

not enter the brake fluid reservoir. Water 
will significantly lower the boiling point of 
the brake fluid and could cause vapor lock.

CAUTION:

ECA13540

Brake fluid may damage painted surfaces 
and plastic parts. Therefore, always clean up 
any spilt brake fluid immediately.

3. Bleed:
