The braking system is one of the most important systems for saving driving. Without brakes, you can not stop the car if it will be necessary, which can endanger the lives of others or your. Fix the broken brakes is not the easy task. Each part of the system, for its correct operation, should be in good condition, and the definition of problems, as well as specific problems, requires the availability of basic knowledge of the mechanics of the relative operation of the system. We can help you with the diagnosis the problem or you can do it yourself.

1. Go for a test drive to find what’s broken

Start the engine and press the brake pedal while the car is in neutral gear or in the parking position to check the brake pedal travel. For this, you can gently press the pedal and see how far the pedal goes before meeting resistance. The normal course in different cars is different, but basically, it should not be more than ¼ the distance from the top position to the floor. Then pass harder and keep a strong pressure to see if the pedal is weakened or gradually starts to move downward as long as you hold it. Next, you should quickly depress the pedal several times to see if the pedal is returning to the same position after each press. If the pedal stops in a higher position, when the brakes are under pressure, the brake hoses are inflated.

2. Note if the car slows down normally

Be especially attentive to various vibrations or changes in the resistance of the brake pedal. This may be an air intake in the brake hydraulic system. You must do such that the wheels of the car rotate in directions. The ineffective brakes will pull the car in the opposite direction, while the badly acting brakes will sharply pull the car to the side where the brake is not functioning properly.

3. Inspect the visible components of your car’s brake system.

Park your car on a firm, level surface. Lock the wheels and lift one wheel with a jack and then inspect the surface of the vehicle’s brake rotors, they should be smooth and shiny with a uniform silvery color. Purple or cyanotic color indicates that they are overheated, and roughness, twisted grooves, or granularity and spots on the surface indicate abnormal wear or deformation of the rotor. If the wheels are raised, then try to swing them and see if there are any unusual movements in the wheel bearings. Turn the wheel and you can hear the sounds of uneven contact in the brake system. Now you will need help in depressing the brake pedal and checking whether the wheel is locked or not.

4. Check the brake fluid.

Its level should be between the top and bottom marks.

5. Change the brake pads in your car.

If, when you use brakes, you hear a scratching sound or a friction sound, this may indicate that you need to replace the brake pads.

6. Check the vacuum system of your car for leaks.

If the brake pedal is pressed with difficulty, then most likely the vacuum system needs to be repaired.

All these steps show you that the car can have really different problems and you can spend huge your time for diagnostic the problem, but this isn’t mean that you can fix the problem yourself. We can make diagnostic for you and give advice about buying Mercedes break parts, which are the best on the market and have the good price with high quality. We save your time and money.
