(4) Push the piston with hand, and turn the cylinder body to
remove the straight pin. (with ABS)
(5) Push the piston with hand, and remove the piston bolt and
washer. (without ABS)
(6) Pull out #1 piston, piston guide block, spring, cup and washer
straightly.
Note: If angle appears in the pulling process, it may cause
damage to the cylinder wall.
(7) Put two blocks and cloth on the workbench. Put the flange of
the master cylinder against the block edge and knock it till #2
piston and spring get out of the cylinder.
Tips:Brake System -Brake Master Cylinder Assembly4-88 Make sure the distance (A) between the working cloth and the block's top is at least 100mm.
Note:
If angle appears in the pulling process, it may cause damage to the cylinder wall.
5. Check the brake master cylinder.
(1) Check the cylinder wall whether there is any rust or nick.
(2) Check the cylinder wall whether there is any abrasion or damage.
Note:
If necessary, clean or replace the brake master cylinder.
Tips:
Clean the assembled parts with compressed air.
6. Install the brake master cylinder.
(1) Fix the brake master cylinder on the bench clamp.
(2) Apply the lithium soap-base glycol lube on the rubber parts with arrow.
(3) Install # 2 and # 1 pistons, spring, piston guide block, cup and washer.
Note:
If angle appears in the installation process, it may cause damage to the cylinder wall. Be careful not to
damage the edge of the cup on the piston.

Brake System -Brake Master Cylinder Assembly4-89 (4) Push the piston, and install the straight pin on the cylinder
body. (with ABS)
(5) Push the piston, and install the new washer and piston bolt.
Torque: 10N.m
(6) Push the piston, and install the snap ring with snap ring pliers.
(7) Install the O-ring on the brake master cylinder.
7. Install the Brake fluid reservoir.
(1) Apply the lithium soap-base glycol lube on the Brake fluid reservoir connector, and install it on the brake
master scylinder.
(2) Install the pin on the brake master cylinder with punch and hammer.
8. Check and adjust the vacuum booster push bar.
(1) Install a special tool on the brake master cylinder,and lower
the special tool mandril till it touches the piston.
(2) Mark the mandril top surface of the special tool with chalk.
(3) Overturn the special tool, and leave a clearance between the
special tool and the vacuum booster.
Tips:
If there is clearance between the special tool body and the booster hull, it means that the clearance is
standard value. If there is no chalk trace on the booster push bar, it means that the clearance exceeds the
standard value.

special tool till the push bar touches the mandril head.
9. Install the brake master cylinder.
(1) Install the brake master cylinder on the booster with two bolts.
Torque: 13N.m
(2) Connect the two brake oil pipes to the brake master cylinder
with a special tool. (with ABS)
Torque: 15N.m
(3) Connect the three brake oil pipes to the brake master cylinder
with a special tool. (without ABS)
Torque: 15N.m
(4) Connect # 1 clutch storage tank oil pipe with clip. (Manual
transaxle type)
(5) Insert the brake fluid level alarm switch connector.
10. Add the brake fluid to the Brake fluid reservoir.
11. Discharge the air in the brake master cylinder.
