4) Unscrew the fixing bolt of brake caliper

and pull out brake caliper outward.

5) Remove the brake lining

Note: mark the linings that have been

undergone running in. Never replace brake

disc if brake linings have side wear. Never

replace brake lining only if the thickness of

brake disc is equal or less than minimum

thickness. Pay attention to the minimum

thickness of brake lining, and then clean the

brake lining. Never apply grease to the

back plate of brake lining.

6) Check the damage status of dust seal ring

and replace it if necessary. Clean the

contact surface of the brake piston, and

apply thin muffle grease on it.

Note: dust seal ring shall not contact muffle

grease to prevent from expansion. To prevent

from severe vehicle body damage due to

piston flying off, never put finger before

caliper piston to attempt to seize or protect it

when using compressed air.

7) Remove piston

Blow compressed air into the caliper inlet,

then the piston will be pulled out of piston

shield.

8) Inspect the piston to see whether there are

scratch, crack, erosion, plating wear or

damage, etc. And replace it if necessary.

Hint: The installation procedure of lining is

opposite to that of removal!

3. Replacement of Rear Brake Disc

ⅰRemoval

1) Remove the tire.

2) Loosen the fixing bolt of brake caliper assembly, then remove the brake caliper and tie it to

one side.

Hint: keep brake lines connectted.

3) Use two bolts to tighten it to the brake

disc through two preset holes, and then

remove the brake disc.

Caution: never knock the friction ring via a hammer or equivalences when removing the brake

disc.

ⅱInstallation

Replace the fixing bolts of brake disc. And thoroughly clean the contact surface of wheel hub, and

then eliminate the erosions if necessary. Uneven contact surface will result in brake disc

deformation!

Caution: Never perform surface finishing for brake disc for the purpose of solving the following

troubles.

T11 Service Manual Chassis System

□ Brake noises, for example, roar or squeal
□ Undue wear of brake lining
□ Brake disc surface erosion
□ Brake disc fading

Only under the circumstances of one or a combination of the following items can the brake disc is

subject to surface finishing:

□ Grave scratches on brake disc surface and the depth exceeding specification.
□ Brake jump due to the following conditions:

– Transverse jump exceeds limit.
– The thickness deviation of brake disc exceeds specification.
– Erosion or pitting penetration exceeds brake disc surface.

Remark: Please refer to the overhaul of front brake disc to inspect the brake disc.

4. Rear Brake Parts

1) Inspection and maintenance

a. Measure the thickness of brake lining pad.

Measure the thickness of brake lining pad via

ruler. If the thickness of lining pad is less than

or equal to minimum value, or the wear is

severely non-uniform, the lining pad shall be

replaced.

b. Measure the thickness of brake disc.

If the brake disc thickness is equal or less than

minimum thickness value, please replace the

brake disc. If there is scratch or irregular

wear on the brake disc, the brake disc shall be

grinded and finished via machine tools or

even replaced.

c. Measure the run-out of brake disc.

(a) Tighten the brake disc via two hub

nuts.

Hint: special tools shall be used to clamp the

brake disc when measuring the run-out value.

Torque: 120N.m

(b) Measure the run-out value of brake

disc via micrometer at the location

where is 10mm away from disc

exterior margin. If the run-out value

of brake disc is equal or more than

the maximum value, inspect the axial

clearance of bearing and the run-out

of vehicle axle wheel hub. If

bearing free play and the run-out of

vehicle axle and hub are in good

condition, adjust the run-out value of

brake disc.
