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 14# open-end
wrench to loosen the oil pipe nut joints at the hydraulic
control unit counterclockwise. The nut torque: 21N.m (2.1
kgf.m, 15 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. Remove the 3 wire ties
⑸
, and remove the wheel speed
sensor wire
⑶
. 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
⑷
, and take off the
FC-HU hose.
If you need to remove the hose bracket
⑵
, you can use 4#
inner hexagon to remove the bolt
⑴
and then take it off. If
you only remove the hose, you can skip this step.
d. 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. Check whether the
cable sheath of the wheel speed sensor cable is damaged. If
the sheath is frayed, it can be glued with electrical tape to
prevent short-circuit.
RC-HU and wheel speed sensor (rear wheel)
a. Locate and remove the wheel speed sensor
⑴
connector on the inside right of the middle of the frame.
b. First remove the 3 pieces of wire clamp
⑶
, and then pull
out the wheel speed sensor
⑴
and the RC-HU hose from the
3 pieces of oil pipe clamp
⑵
. If you need to remove the
tubing clamp (2), you can use 4# inner hexagon to remove
the bolts and then you can take it off.
