All Peugeot 305 models have a modern brake system with disc brakes on the front wheels and drum brakes on the rear. The brakes are actuated by a hydraulic system equipped with a servo booster and having a dual master cylinder operated by a foot brake pedal. The brake system includes a rear brake pressure regulator that prevents the rear wheels from locking.
The handbrake is cable operated and only acts on the rear wheels.
Parts of the brake system, manufactured by different companies, may differ from each other and are not always interchangeable. Be careful when buying spare parts and, if possible, compare them with the old ones.
