Your brake pads are the ones that provide the main braking action on your Mercedes Benz E55's brake system. When these brake pads start to fail, the efficiency and functionality of your car's entire brake system will be jeopardized. That's why it's important that you know what to watch out for with your brake pads' condition so you can solve the problem before it gets worse. Here are a couple of brake pad problems that you might encounter and the causes behind them.
Hearing squealing sounds from the brakes of your Mercedes Benz E55 is not always caused by improper usage of the car's brakes. It could also be a sign that your brakes are getting worn out. If the squealing sound that you hear is high-pitched, this is a clear indication that your brake pads need to be replaced immediately. The manufacturers used the squealing sound as a technique to let you know that your brake pads are worn out. If the squeal sound is continuous, check if there are problems with the wheel bearings. If the sound you hear is intermittent and not high-pitched, your brake pads could be dirty or dusty. This problem can be easily solved by having the car washed at an automated car wash station. Just make sure to do a visual inspection first because these sounds could also be caused other problems such as poor condition of backing plate, low quality brake liners, improper alignment of brake adjusters, broken retaining springs, improper brake shoes, and a whole lot more. Make it a point to fix this problem as soon as possible as it can cause more problems on the brake rotors.
If you notice that your brake pedals require too much force when you press them, the problem could be in the vacuum system. Leaks in the vacuum system can result to the loss of the negative pressure that is needed to make the brakes work. Other possible causes of this problem include a bad brake booster, an obstruction that disables the brake fluid to reach a particular part in the brake system, or worn out brake pads.
