INFOID:0000000009267543

INSPECTION AFTER INSTALLATION

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 leakage.

CAUTION:

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

worn or deformed) part if any brake fluid leakage is present.

Removal and Installation

INFOID:0000000009267545

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 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 master cylinder body when handing the master cylinder assembly. Do not hold the piston

because the piston might become detached if pulled strongly.

• Refill the reservoir tank with new brake fluid “DOT 3”.

• Do not reuse drained brake fluid.

• Do not reuse master cylinder O-ring.

NOTE:

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

ing.

6. Disconnect the brake pipe from the master cylinder assembly with a flare nut wrench.

CAUTION:

Do not scratch the flare nut and the brake tube.

7. Remove the master cylinder assembly.

CAUTION:

• Do not deform or bend the brake pipes.

• Do not depress the brake pedal after the master cylinder assembly is removed.

• The piston of the master cylinder assembly is exposed. Do not damage it when removing the

master cylinder.

• The piston may drop off when pulled out strongly. Do not hold the piston. Hold the cylinder body

when handling the master cylinder assembly.

8. Remove and discard the O-ring.

INSTALLATION

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 reuse the O-ring.

Note the following, and install in the reverse order of removal.

• Do not depress the brake pedal after the master cylinder assembly is removed.

• Apply silicone grease to the brake booster location (A) prior to

installing the master cylinder assembly to the brake booster.

• The piston of the master cylinder assembly is exposed. Do not

damage it when handling the master cylinder and check that no dirt

and dust are present on the piston before installation. Clean it with

new brake fluid if necessary.

• The piston may drop off when pulled strongly. Do not hold the pis-

ton. Hold the cylinder body when handling the master cylinder

assembly.

• Do not deform or bend the brake pipes.

• Temporarily tighten the brake tube flare nut to the master cylinder

assembly by hand. Then tighten it to the specified torque with a

flare nut torque wrench. Refer to 

BR-21, "FRONT : Exploded View"

.

CAUTION:

Do not scratch the flare nut and the brake tube.

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

• After installation, perform the air bleeding. Refer to 

BR-12, "Bleeding Brake System"

CAUTION:

Do not reuse drained brake fluid.

• Perform inspection after installation. Refer to 

BR-29, "Inspection"

.
