c. Push the piston to the end in the direction of the arrow
with the help of a tool. If the resistance is high, you can refer
to the method of adding brake fluid to the front brake main
pump to remove the upper cover and then push. If the spring
on the caliper falls off, it needs to be reinstalled in the
direction shown in the figure.
d. Grasp the outer brake pad with your left hand and insert
the pin ② with your right hand, being careful not to insert it
to the end. Install the inner brake pad in place, then insert
the pin to the end and use the 5# inner hexagonal lock
pin ② . Be careful not to install it backwards, the grooved
side faces the brake disc; the black metal back plate faces the
caliper.
e. After adjusting the position of the brake pad, reinstall
the bolt ③ and lock it with a 12# sleeve. Standard torque:
24N.m (2.4 kgf.m, 18 lbf.ft).
f. Use a flat-blade screwdriver to put back the nut ① and
tighten it.
g. Repeatedly pinch and hold the brake handle to check
whether the brake returns to normal hydraulic resistance.
5.3 Abnormal sound of brake pads
The main reasons for the abnormal noise of the brake pads
are as follows:
a. The brake pad is worn to the limit. If it is a new brake
pad, check whether there is any foreign matter caught
between the brake disc and the brake pad. It can return to
normal after replacing new brake pads or cleaning foreign
objects.
b. Use non-original brake pads with too high hardness and
replace them with original ones.
c. The brake disc bolts are loose, and the tightening bolts
can be restored to normal.
d. Braking system failure, such as the caliper sliding shaft is
not reset due to rust; the brake pads and spring pads are not
installed correctly. Derust or re-assemble correctly.
e. The brake disc is out of tolerance, and it can be restored
to normal by replacing the new brake disc.
6. Replace the brake disc
●The veh icle must be parked on a flat and stable ground or a lifting platform.
●After replacing the brake discs, brake pads, or reassembling the front and rear wheels, the brake handle must be operated
repeatedly until the brakes restore the braking effect.
●Conta minated disc brake discs and disc brake pads will reduce the braking effect. Please replace with new disc brake discs and
clean the contaminated brake discs.
●After disassembling the brake disc or rim assembly, please do not operate the brake handle.
●Check the new brake disc for run out ≤0.08mm (0.003 in) before assembling.
