Steering wheel A three stage softening type with airbag, diameter of 370 mm, and maximum steering circle number of 3.08. Main technical parameters Front wheel camber/rear wheel camber -0° 43′ ± 30′ /-0° 43' ± 30' +10°21′ ± 30′ Kingpin caster +1°49′ ± 30′ Front wheel toe-in/rear wheel toe-in -0° 01′ ± 15′ /+0° 14' ± 15' Inside wheel steering angle (°) 32°-37° Outer wheel steering angle (°) 28°-30° Steering wheel rotation number (n) 3.08 Steering system angle ratio (i0ω) 19.03 Brake system Service brake type The service brake system adopts a hydraulic vacuum power-assisted type. The front/rear brakes are disc and drum brakes respectively. The front brake uses a ventilated disc, and the brake pedal is a suspended pedal with vacuum booster. Brake line is in a dual-circuit diagonal (X type) arrangement, adopting a ABS + EBD anti-lock and braking force distribution system. Service brake booster and master cylinder Single stage Φ9inch vacuum booster, series dual-chamber brake master cylinder, cylinder bore Φ22.22 mm, stroke 32 mm Brake reservoir Shares with the clutch master cylinder reservoir and installed with a brake fluid level alarm. Brake pedal stroke Free play: 6-9 mm, working stroke: 37-40 mm. Brake pedal pressure <380 N (no load) <480 N (full load) Parking brake The parking brake system uses a mechanical remote ratchet cable control mechanism to control the rear wheel drum brake. Brake lever's functional stroke is 5-8 gearteeth.
