remove the copper pad ⑵ , and remove the RC-HU oil pipe.
Refer to the steps for adding brake fluid to the main pump of
the rear disc brake. Remove the upper cover of the main
pump to accelerate the discharge of the brake fluid. Bolt
⑴
Standard torque: 32N.m (3.3kgf.m, 24 lbf.ft).
b. Use a 14# sleeve to remove the bolt (3). Standard
torque of bolt (3): 24N.m (2. 4kgf.m, 18 lbf.ft).
c. Refer to the procedure for replacing the brake pads to
remove the brake pads first.
d. Disassemble the rear disc brake caliper
Refer to the previous steps to disassemble the front disc
brake caliper piston to remove the rear disc brake caliper
piston. Check the piston and caliper cylinder for scratches,
damage, pits, etc. Check whether the pin is deformed. The
points that should be paid attention to during cleaning and
assembly are detailed in the previous description, and will
not be repeated here.

Caution:
●Apply silicone grease to the surface of the pin and bush
indicated by the arrow.
●The oil seal and dust seal sh ould be replaced with new ones
after disassembly. DOT4 brake fluid should be applied to the
oil seal and piston, and silicon grease should be applied to
the outer ring of the dust seal.
●Apply thread fastening glue to the thread of the caliper pin,
torque: 27N.m (2.8kgf.m, 20 lbf.ft).
●The torque of the air release nozzle: 7
～
9N.m (0.7
～
0.9kgf.m, 5
～
7 lbf.ft).
●The open end of the piston should face the caliper
mounting plate, and do not install it backwards.
●If there is slight rust on the surface of the piston, it can be
polished off with 2000 mesh fine sandpaper.
Brake hose and wheel speed sensor
Check the gap between the wheel speed sensor
and the induction ring gear
Caution:
●The vehicle needs to be pa rked on a stable lifting platform
or on a level and level ground.
Put down the main bracket to park the vehicle firmly and
let the rear wheels hang in the air.
Use a feeler gauge to check whether the gap between the
wheel speed sensor and the ABS induction ring gear is 0.4-
1.2mm (0.02-0.05in).
If the gap is not within the specified range, check whether
the wheel speed sensor is damaged and whether the ABS
induction ring gear is loose. The front wheel needs to check
whether the position of the sensor installed on the front disc
brake caliper mounting plate is deformed, and the rear wheel
is to check whether the mounting position on the rear rocker
arm is deformed and whether the rear wheel nut is loose.
Front wheel
Rear wheel
Remove the brake hose and wheel speed sensor
Caution:
●Check whether the brake h ose is normal according to the
maintenance table.
●Before disassembling the brake hose, drain the brake fluid
before operation.
●Before removing the hose, remove the upper cover of the
front and rear disc brake main pump, loosen the disc brake
oil pipe bolts from the front and rear disc brake calipers to
drain the brake fluid.
●The discharged brake fluid needs to be properly disposed
of, and it is forbidden to continue to use it. It is forbidden to
dump at will to pollute the environment; or put it at will, etc.
It should be handed over to a qualified recycling unit for
proper disposal.
