4 Common Causes of Hard Brake Pedal in Mercedes-Benz

Mercedes-Benz is a subsidiary of Daimler AG. It has established itself as a popular German luxury and commercial vehicle manufacturer. It sells different variants of vehicles including sedans, wagons, convertibles, sports cars, SUVs, and coupes. It has emerged as a market leader in the automobile industry due to its muscular engines, spry handling, high-tech infotainment system, and spacious interior and exterior designs. It is also known for its highly advanced safety features which include an advanced brake assist system, forward collision warning, automatic emergency braking, adaptive cruise control, and anti-lock braking system.

The braking system helps the driver to regulate the speed of a vehicle. Failure of such a vital safety system might cause a fatal road accident. So, the braking system needs special attention to operate efficiently. Warning signs which show that the braking system of your Mercedes-Benz has some defects should not be neglected. Detect and repair the faults in the braking system of your car as soon as possible to keep it in its top order. Moreover, regular maintenance is also necessary to enhance the effectiveness of the braking system of your vehicle. Have a look at some of the most prominent causes of braking system failure in your Mercedes-Benz.

Causes of hard brake pedal

The braking system of your Mercedes-Benz is a complex system that relies on the hydraulic brake fluid to stay operational. Brake fluid is a non-compressible fluid that facilitates the movement of different components of the braking system. When you press the brake pedal, the brake fluid amplifies and transfers that force to the rotors and thus reduces the speed of a vehicle. However, contamination of brake fluid or faults in the master cylinder and other crucial components of the braking system could jeopardize the braking system of your vehicle. Hard brake pedals are signs of a defective braking system that needs immediate attention. Let us discuss the factors responsible for the emergence of such kinds of unusual behavior by the braking system of your Mercedes-Benz.

Brake fluid contamination:

The primary job of brake fluid is to transfer the force applied on the brake pedal to the brake pads and thus reduces the speed of a vehicle. However, it is hygroscopic and could absorb water molecules from its surrounding. The presence of an excess amount of water molecule could cause hard brake pedals in your Mercedes-Benz unresponsive. Moreover, the presence of an excess amount of foreign contaminants in brake fluid could also cause hard brake pedals in a car. So, check the brake fluid of your Mercedes-Benz regularly and replace it if necessary.

Defective valves:

The primary job of brake proportioning valves in a vehicle is to regulate the pressure between the front and rear brakes in order to avoid wheel lockup and skidding during an emergency braking event. However, faults in these valves and other crucial components of the braking system could also cause hard brake pedal in your Mercedes-Benz. So, check the condition of the valves as well as other sensitive components of the braking system regularly and repair the faulty components immediately to keep the vehicle operational.

Faulty vacuum booster:

The main job of a vacuum booster is to assist the driver by reducing the braking effort. However, a defective vacuum booster could not do its job efficiently as a result of which vacuum level within the system destabilizes and you will get a harder brake pedal. So, early signs of a defective vacuum booster in your car should not be overlooked and it should be repaired or replaced as soon as possible.

Faulty hardware:

Faults in the master cylinder or other vital components of the braking system could also be responsible for hard brake pedals in Mercedes-Benz. Moreover, faults in those components could jeopardize the braking system which could lead to a fatal collision. So, repair those defective components immediately to enhance the efficiency of the braking system of your Mercedes-Benz.

Wrapping up

Hard brake pedals in your Mercedes-Benz could lead to a fatal road accident that might cost you your life. So, the emergence of such kinds of warning signs which shows that the braking system of your vehicle has some faults should not be overlooked. Check the level and quality of brake fluid regularly and replace it if necessary. Moreover, faulty components of your Mercedes-Benz should be repaired as soon as possible to keep the braking system in working condition.
