BMW Brake Booster, Brake Caliper and Brake Dust Shields
BMW Brake booster is a mechanical component which is vacuum-driven and is in charge of delivering vacuum pressure to the entire power brake system, and that is why also known as vacuum booster or vacuum servo. BMW brake booster is a silent device which does not need gasoline or electricity. BMW brake boosters are cuddled between the brake master cylinder and firewall which conveys a greater amount of braking power with less effort or minimum stress on the brake pedal else you would have dead beat limbs.
A low or hard brake pedal may lead to a bad brake power boost unit which is caused due to many reasons such as low engine vacuum, a leak in vacuum hose, a damaged booster, a faulty check valve etc. In a brake system if a scraping noise is audible to you then it is due to a metal-to-metal contact however squealing of brake is due to the vibration caused in between the brake disc pads and brake caliper. Variations in rotor thickness, material, type and condition may pull the brake to one side. If in case BMW brake boosters are either decayed or damaged, then it should get replaced without any delay.
BMW brake caliper generates friction with the rotors by pressing the brake pads beside the surface of the brake rotor to slow down or stop your ride. The BMW brake calipers are positioned right above the rotor just like a clasp. Proper greasing of the caliper slides is important for it avoids untimely rusting of BMW brake caliper and further ensures its longer life and functions more smoothly. It is recommended to always choose a silicone-based lubricant as it does not contain any petroleum or lithium constituents. A faulty brake caliper may let your ride to change the direction whenever brake is applied or sometime it may get engaged constantly leading to abrasion, heat, and perhaps fire!
A set of BMW disc brake dust shields, protects your wheels and its high-dollar rims from the unsightly disc brake dust without affecting the braking ability of your ride. BMW disc brake dust shields are a piece of material which is fitted in an aluminum case and is placed in between your BMWs' rim and its brake disc. The disc brake dust from the disc brake system is kept away from being blown-out to the front of wheel which may ruin that look on which you have spent a lot of money. BMW disc brake dust shields do not contribute to the disc brake cooling or disc brake overheating. So, to achieve the look you want and to protect your BMW wheels from the brake dust you must choose a set of BMW disc brake dust shield for both front and rear wheels.
A worn-out part may badly affect other parts in the brake system of your sedan for example leakage in the master cylinder may cause booster failure. That is why it is necessary to check each and every brake components on time and replace them.
