CAUTION:

• All hoses and tubes must be free from excessive bending, twisting and pulling.

• Make sure there is no interference with other parts when turning steering clockwise and counter-

clockwise.

• The brake system is an important safety system. If a brake fluid leak is detected, always disassemble

the parts. Replace applicable part with a new one, if necessary.

• Do not bend or twist brake hose sharply, or strongly pull it.

• When removing components, cover connections so that no dirt, dust, or other foreign matter gets in.

• Do not reuse drained brake fluid.

CAUTION:

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe

it off immediately and wash with water if it gets on a painted surface.

• Do not allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

REMOVAL

1. Remove the wheel and tire using power tool.
2. Loosen the flare nut using a flare nut wrench and separate the brake tube from the brake hose.

CAUTION:

• Do not scratch the flare nut or the brake tube.

• Do not bend sharply, twist or strongly pull out the brake hoses and brake tubes.

3. Remove the lock plate and remove the brake hose from the vehicle.
4. Loosen the flare nut using a flare nut wrench and separate the brake tube from the wheel cylinder.

Remove the brake tube.

INSTALLATION

1. Connect the brake tube to the wheel cylinder. Temporarily tighten the flare nut by hand until it does not

rotate further.

2. Connect the brake hose to the brake tube. Temporarily tighten the flare nut by hand until it does not rotate

further. Secure the brake hose to the bracket with the lock plate.

CAUTION:

• Check that all brake hoses and brake tubes are not excessively bent, kinked or twisted.

• Make sure that interference does not exist between the brake hoses and other parts when the

suspension moves.

3. Tighten the flare nut to the specified torque using a crowfoot and torque wrench. Refer to 

BR-24, "REAR :

Exploded View"

.

CAUTION:

Do not scratch the flare nut or the brake tube.

4. Refill with new brake fluid and perform the air bleeding. Refer to 

BR-12, "Bleeding Brake System"

.

CAUTION:

Do not reuse drained brake fluid.

5. Install the wheel and tire. Refer to 

WT-45, "Exploded View"

.

6. Perform inspection after installation. Refer to 

BR-25, "REAR : Inspection"

.

BRAKE PIPING

1. Check the brake hoses and tubes for the following: no scratches; no twist and deformation; no looseness

at connections.

CAUTION:

Clearance with brake hose and each parts being secured more than 10 mm (0.39 in) in unladen
condition

*

.

*: Fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in desig-

nated positions.

2. Depress the brake pedal with a force of 785 N (80.1 kg-f, 176.5 lb-f) and hold down the pedal for approxi-

mately 5 seconds with the engine running. Check for any fluid leaks.

CAUTION:

Retighten the applicable connection to the specified torque and repair any abnormal (damaged,

worn or deformed) part if any brake fluid leaks are present.

Removal and Installation

INFOID:0000000009364842

CAUTION:

• 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.

• Do not scratch the piston of brake master cylinder when installing/removing because the piston is

exposed. Check for any dust on the piston, and wash with brake fluid if needed.

• Hold the brake master cylinder when handing the brake master cylinder. Do not hold the piston

because the piston might become detached if pulled strongly.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

REMOVAL 

1. Remove battery tray. Refer to 

PG-68, "Removal and Installation (Battery Tray)"

.

2. Remove air cleaner and air duct. Refer to
