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.

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.

Check1. Check the brake booster.
(1) Air tightness check
a. Start the motor, and shut it down after one or two minutes,
then step on the pedal several times slowly.
Tips:
If the pedal goes down greatly at the first step, but it gradually
goes up after the second and third steps, it means the air
tightness is good.Brake System -Vacuum Booster4-92 b. When the motor is running, step down the brake pedal, and then shut down the motor.
Tips:
If the reserved distance does not change thirty seconds after
the pedal is stepped down, it means the air tightness is good.
(2) Operation check
a. When the ignition switch stays in OFF position, step on the
pedal several times, and then check that the reserved
distance should not change.
b. Step down the pedal, and start the motor.
Tips:
If the pedal goes down a little, it means the operation is ok.
