General characteristics
Design type - Dual-circuit braking system with diagonal splitting, with brake booster and load-dependent pressure regulator in the brake drive system
Front wheel brakes - Disc, self-adjusting
Rear wheel brakes - Drum or disc (v6 engine and with ABS), self-regulating
Parking brake - Affects the rear wheel brakes
