Chery Tiggo T11 LHD. Manual — part 20

T11 Service Manual Chassis System

□ Deflection driving
□ Abnormal performance

Maintain brake surface precision can prolong the service life of lining. Brake disc slight scratch

whose depth is less than 1.5mm will not influence braking performance, as normal use can also

result in slight scratch.

6. Replacement of Brake Caliper

1) Removal procedures

Caution: prior to achieving stable brake pedal stroke, never move the vehicle to prevent from

personal injury!

a. Discharge a small amount of brake fluid from master cylinder.

b. Lift and properly sustain the vehicle.

c. Mark the relative locations of wheel and hub.

d. Refer to tire and wheel removal and installation to remove the front tire and wheel assembly.

e. Unscrew the fixing bolt of brake caliper

f. Fix a large C-shape clamp 2 onto the top

of brake caliper, and press it to the back of

external brake lining.

g. Tighten the C-shape clamp till the caliper piston is pushed to an adequate depth in the caliper

cylinder sleeve so as to make the brake caliper slide out of the brake disc.

h. Remove the fixed bracket of the lining thickness sensor harness.

i.

Refer to the replacement of brake lining.

j.

Remove the dust cover of oil cylinder.

Remove dust cover from oil cylinder by

screwdriver.

k. Remove the piston

(a) Use a piece of wood board to stop the

piston, put the board between pistons,

and then insert the lining from one

side.

(b) Use compressed air to carefully

squeeze out the piston through switch

port. Put a shield (for example,

hardwood) at the notch of brake

caliper to protect the piston. Never

hold the piston by finger, as it is too

dangerous!

l.

Inspect the guide sleeve (5)

When manually push the guide sleeve, it must

be smooth. If stagnation or heaviness occurs,

please replace the guide sleeve

Note: Grease shall be applied to the guide

sleeve when assembling.

m. Remove the seal ring via plastic pin

carefully. Use alcohol to clean the brake

cylinder and parts, and apply compressed

air to blow it dry. Check through the

surface of brake cylinder, piston and

flange. Never carry out mechanical

machining to brake cylinder and piston.

2) Installation

a. Bray brake cylinder grease on the cylinder,

stud plug and seal sleeve, and then fix seal

ring in the ring slot at the tail of brake

cylinder. Finally fix the dust seal ring

into the front ring slot and press the

overall seal ring into the ring slot.

b. The area between dust seal ring and brake

caliper house must be kept dry. Never

contact brake cylinder grease or brake

fluid to ensure the dust seal ring properly

located.

c. Use extended piece sold in the market to

fix the brake piston and gently press it

onto dust seal ring, and then blow dust

ring via compressed air (maximum 3bar).

Finally fix the sealing ring over the brake

piston.

d. Use brake fluid to soak the dust seal ring and brake piston to enable the seal ring to past

through the piston easily.

7. Inspection and Replacement of Brake Lining

For all of the Chery vehicles, genuine brake linings shall be used for replacement to prevent from

affecting braking performance.

ⅰ Removal

1) Lift and properly sustain the vehicle to

remove trim board.

Note: prevent the front surface of the trim

board from scraping ground after dismounting

the trim board.

2) Unscrew the five fixing bolts of the wheel

and then remove the wheel.

Torque: 120N.m

Note: The tightening torque of tire bolt shall

be highlighted.

3) Unscrew the fixing bolt of the harness of

the lining wearing indication lamp, and

then pull out the plug of lining thickness

warning lamp. (Remark: the plug of

lining thickness warning lamp is a kind of

preset one.)

4) Loosen the guide bolt above brake caliper

(a), and then loosen the guide bolt below

brake caliper. And finally take out the

brake caliper. Never connect brake

caliper with brake hose to prevent from

brake hose damage.

Installation instructions:

Only clean the guide bolt, but never apply

grease to the guide bolt.
