6.1 Warning and precaution

6.1.1 Warning and precaution

Warning for ABS Component handling

Warning!

Certain parts in the antilock brake system (ABS) can not be independently repaired; if certain system parts are
tried to dismantle or disconnect, personal injury and/or abnormal operation of system may be caused; therefore,
only the parts capable of being dismantled and installed can be repaired.

Warning for brake dust

Warning!

When repairing the wheel brake part, please avoid the following operations:

–Do not repair or grind the brake lining.

–Do not polish the brake padwith sand paper.
–Do not clean the wheel brake parts with dry brushes or compressed air.

Warning!

Some modes or after-sales retrofitting part may contain fibers which are mixed in the dust. Inbreathing
dust containing fiber can damage your health severely. Please use a water-dampened cloth in order to
remove any dust on brake components.

Warning for brake fluid

Warning!

The brake fluid is made of polyethylene glycol, which is extremely easy to absorb humidity and moisture. Do not
use the brake fluid that may be polluted by water in open container, because the use of improper or contaminated
brake fluid may lead to system failure, losing control of the vehicle and personal injury.

Warning for brake fluid irritation

Warning!

The brake fluid has irritation to skin and eyes. Only adopted measure as follow:

Eye contact - completely rinse eye with clean water.

Skin contact – use soap water or clean water to rinse.

Warning for brake pipe replacement

Warning!

Warning: Carefully route and retain the brake pipes replacement. Always use the correct fasteners. Otherwise, it
may cause damage to the brake pipes and brake system resulting in personal injury.

Important precaution on adding fluid to the brake system

Notes:

When adding the brake fluid into the brake master cylinder, only use the brake fluid in the clean and sealed brake
fluid container in accordance with Super DOT4. The use of any type of fluid other than the recommended type of
brake fluid may cause contamination which could result in damage to the internal rubber seals and/ or rubber
linings of hydraulic brake system components.

Important precaution on brake caliper

1524

Notes:

You should support the brake caliper with a steel wire during dismantlement of the brake caliper to avoid
damaging the brake hose.

6.2.2 Description and operation

6.2.2.1 Description and operation

Front disk-type brake system is composed of:

The front disk-type brake system consists of the following components:

Brake pad: the mechanical output force from the hydraulic brake caliper is acted on the friction surface of the
brake disc.

Brake pad guiding piece: located between the disc-type brake pad and the brake pad mounting bracket to keep the
brake pad moving smoothly, thereby eliminating noise.

Brake disc: the tire and wheel assembly is slowed down through the mechanical output force acted by the
disc-type brake pad on the brake disc friction surface for the braking of the vehicle.

Brake caliper: receive the hydraulic pressure from the brake master cylinder, convert the hydraulic pressure into
the mechanical output force to act on the internal brake pad, and enable the brake caliper piston to automatically
