Release brake fluid
a. Refer to the previous steps to remove the oil pan first,
place the oil pan at the front and rear calipers, remove the
disc brake oil pipe bolts and copper pads first, and drain the
brake fluid into the oil pan, and then refer to the front and
rear disc brake main pumps. Add brake fluid step to remove
the upper cover of the main pump to accelerate the
discharge of brake fluid. Remove the disc brake oil pipe bolts
and copper pads at the main pumps of the front and rear disc
brakes. Only the disassembly steps of the brake hose are
explained here.
b. Press the buckle indicated by the arrow, turn the plug
push rod in the direction indicated by the arrow, and pull out
the plug. In order to prevent the remaining brake fluid from
entering the plug when the hose is removed in the next step,
the plug of the hydraulic control unit can be wrapped with an
oil-resistant film plastic bag.

FMC-HU: Front disc brake main pump-hydraulic control unit
FC-HU: Front disc brake caliper-hydraulic control unit
RMC-HU: Rear disc brake main pump-hydraulic control unit
RC-HU: Rear disc brake caliper-hydraulic control unit
Use oil-resistant plastic bag or plastic film to put it around
the bottom of the hydraulic control unit, and fix it with tape
to prevent the residual brake fluid from dripping on the parts
when the oil pipe nut joint is loosened. Use a 12# open-end
wrench to loosen the oil pipe nut joints at the hydraulic
control unit counterclockwise. The nut torque: 18N.m (1.8
kgf.m, 13 lbf.ft). Wipe up the remaining brake fluid with a
clean non-woven fabric. Take care to take protective
measures and prevent dripping onto the cover or cable
connector.
FMC-HU and RMC-HU
Use an 8# sleeve to remove the bolt ⑴ that fixes the seat
of the oil pipe, pull down the upper part of the FMC-HU hose,
pull it out from the lower part of the direction cover, and
then pull it out from the hose bracket. Check whether the
surface of the removed hose is aging, cracked, damaged,
abraded, etc. Wipe up the remaining brake fluid with a non-
woven cloth, and then wrap the ends of the hose with cling
film or a plastic bag to prevent foreign matter from entering.
Remove and inspect the RMC-HU hose in the same way.
FC-HU and wheel speed sensor (front wheel)
a. Locate the plug of the wheel speed sensor on the left
side of the frame, and pull out the plug after pressing the
anti-release card.
b. For the removal method of FC-HU and wheel speed
sensor caliper, please refer to the section “Removing the
front disc brake caliper”.
c. Cut off the 2 cable ties ⑴ , remove the 3 wire ties ⑺ , and
remove the wheel speed sensor wire ⑹ . Check whether the
cable is damaged. If the cable sheath is frayed, wrap it with
electrical tape to avoid short-circuit and cause vehicle failure.
The front wheel speed sensor is also responsible for
providing a speed signal to the meter to display the speed
per hour.
Use an 8# sleeve to remove the bolt ⑵ , and take off the
FC-HU hose.
If you need to remove the hose bracket ⑷ , you can use 4#
inner hexagon to remove the bolt
⑶
and then take it off. If
you only remove the hose, you can skip this step.
