Diesel or kerosene can be used to clean the brake
fluid to facilitate the next step of decomposition. If the oil
hole is blocked, use a dust blower or a small needle tool
to clear it. After decomposition, use a soft lint-free brush
to clean up all parts. It is not recommended to use a
dust blower for drying. The air compressor with poor
drying or filtering effect may blow dust, moisture or other
debris into the main pump housing that has been
cleaned through the blower; high vacuum can be used
Vacuum cleaner. Before assembling the piston
assembly and spring, apply a small amount of DOT4
brake fluid, and do not apply other lubricating materials
such as lubricating oil, grease or anti-rust oil.
g. Apply an appropriate amount of high-vacuum
silicone grease to the outer end of the handle bolt and
piston assembly according to the previous requirements
for lubricating the movable part of the handle. Refer to
the disassembly steps to reinstall, and follow the
previous steps to add the newly opened brake fluid and
perform the exhaust operation. Note that the copper pad
(3) needs to be replaced with a new one to prevent
leakage. After the assembly is completed, it is
necessary to confirm that the brake has been restored
before driving the vehicle.
Disassemble the rear disc brake main pump
The rear disc brake main pump and the front disc
brake main pump are mirrored and symmetrical. Please
refer to the steps for disassembling the front disc brake
main pump for disassembly.
Disassemble the front disc brake caliper
a. Use 5# inner hexagon to remove bolt
⑴
, and
remove the wire clamp. First use a 12# sleeve to loosen
the disc brake oil pipe bolt
⑷
, pay attention to loosen it
and then tighten it slightly to avoid leakage, otherwise it
will be more difficult to loosen this bolt later. Use 4#
inner hexagon to remove 2 bolts (2) to remove the
wheel speed sensor. Use a 14# sleeve to remove the
bolt (3). Standard torque of bolt
⑶
: 24N.m (2.4kgf.m, 18
lbf.ft); Standard torque of bolt
⑷
: 32N.m (3.3kgf.m, 24
lbf.ft).
b. After wearing waterproof gloves, loosen the bolt
⑷
with a 12# sleeve, and turn the caliper upside down so
that the head of the bolt
⑷
is facing down to drain the
brake fluid into the oil pan. Remove the bolt
⑷
and the
copper pad
⑸
and then remove the FC-HU oil pipe.
Refer to the brake fluid steps to remove the upper cover
of the front disc brake main pump to speed up the
discharge of brake fluid.
c. Remove the brake pads according to the steps of
removing the brake pads
d. Front disc brake caliper disassembly
A dust blow gun can be used to blow in compressed
air from the oil pipe bolts to blow out the piston. Pay
attention to placing towels or other soft materials on the
piston to prevent damage caused by collision between
the piston and the caliper mounting plate; and the dust
blow gun should be kept away from the caliper body. If
the distance is too close, the piston may suddenly fly out
and cause damage. Check the piston and caliper
cylinder for scratches, damage, pits, etc. Check whether
the pin is deformed.
