General information about the braking system (Scorpio 2)

            0

The brake system consists of a master brake cylinder, a brake booster, and disc brakes on the front and rear wheels. The hydraulic brake system has 2 circuits. One brake circuit operates the disc brakes of the front axle, and the other operates the disc brakes of the rear axle. Due to this, despite the failure of one brake circuit, for example, due to a leak, the car can be stopped by braking the wheels of one axle. The pressure in both brake circuits is created by the dual master brake cylinder when the brake pedal is pressed.

Above the main brake cylinder in the engine compartment there is a compensation tank with brake fluid, which should fill all brake circuits.

The brake booster in cars with gasoline engines is driven by an air vacuum. Thanks to the presence of the appropriate valve, the braking force created by the brake pedal is increased if necessary by means of a vacuum. Since the vacuum in the intake manifold of diesel engines is insufficient, these engines have a vacuum pump that creates a vacuum for the brake booster. The vacuum pump is flanged to the rear of the generator and is driven by the generator shaft. The disc brakes of the front and rear axles are equipped with a brake mechanism with a floating caliper. In this mechanism, only one piston is required to press the brake linings to the brake discs. The handbrake acts on the brake mechanisms of the rear wheels via cable rods. Basic adjustment is only required after repairs in which the brake system was disassembled.



Safety note: Cleaning the brakes creates brake dust which can cause health hazards. Therefore, when cleaning the brake system, care must be taken to avoid inhaling this dust.


Brake pads are subject to the operating permit - ABE (Allgemeinen Betriebseriaubnis), in addition, they are intended by the factory for the corresponding car model. Therefore, it is recommended to use only brake pads that have an operating permit from FORD.

Safety instructions: Work on the brake system requires extreme cleanliness and verified work techniques. If the necessary work experience is not available, then work on the brakes should be performed at a service station.


Note: On roads that are very wet from rain, it is necessary to brake from time to time while driving in order to free the brake discs from deposits. Due to centrifugal forces, water is thrown off the brake discs, but a thin silicone film, rubber wear products, grease and other contaminants remain, which reduce the effectiveness of the brakes.


After installing new brake pads, they must be run in. On a section of the road approximately 200 km long, useless sharp braking to a complete stop should not be repeated.

Rusty brake discs produce a squealing noise when braking, which may not be eliminated even after prolonged braking. In this case, the brake discs must be replaced.

Burnt dirt and rain cavities on the brake pads lead to the formation of scratches on the brake discs. As a result, a decrease in braking effect may occur.
