Note: Individual characteristics are also given in the text of the Chapter and, if their implementation is mandatory, are highlighted in bold.
Type | |
| - up to mid-1995 | Dual-circuit, with front disc and rear drum brakes. A pressure regulating valve is installed in the rear brake circuit. The parking brake acts on the rear brakes. There is a vacuum booster |
| - since mid-1995 | Dual-circuit, with front and rear disc brakes. The parking brake acts on individual brake shoes on the rear wheels. There is a vacuum booster |
| - cars with ABS | Dual-circuit, with front and rear disc brakes. The braking system is controlled by a hydraulic unit. The parking brake acts on individual brake shoes on the rear wheels |
Braking mechanisms | |
| - front wheels | Disc brakes with floating calipers, self-aligning |
| - rear wheels | Drum or disc with floating brackets, self-aligning |
| - parking brake | Affects the rear wheels. Individual brake pads with inner sides of the rear brake discs |
