BASIC BRAKE SYSTEM ± General Information35A-3
GENERAL INFORMATION35100010120
The brake system has high reliability and durability
which maintains excellent braking performance and
braking feeling. The main features are as follows.

A dual type master cylinder is equipped in all
models.

Both a single type and a tandem type brake
booster have been adopted.
The following type of brake have been adopted.
Front: Floating caliper, 2-piston, ventilated disc
brakes (V4-W43, V5-W43) or floating caliper,
1-piston, ventilated disc brakes (V4-S60,
V5-S60)
Rear: Leading-trailing type drum brake.
