Gravity bleeding represents a brake bleeding approach that depends on gravity to facilitate the elimination of air bubbles from a car’s hydraulic brake traces. This process entails opening the bleeder screws on the brake calipers or wheel cylinders, permitting brake fluid to movement by way of the system, pushed solely by the power of gravity, thereby purging trapped air. As an illustration, if a mechanic is changing a brake caliper, they may use this methodology to make sure no air stays within the newly put in element.
This method presents a number of benefits, primarily its simplicity and requirement for minimal specialised gear. It’s particularly helpful in conditions the place entry to energy bleeders or different strain bleeding instruments is restricted. Traditionally, gravity bleeding served as a standard observe as a consequence of its accessibility and cost-effectiveness. The method can cut back brake pedal journey, enhance brake responsiveness, and enhance total security and efficiency.
