The reason for loud brake noise when reversing is: Brakes primarily operate during forward vehicle motion, causing prolonged unidirectional wear on the brake pads. This creates burrs on the reverse side, which produce abnormal sounds when rubbing against the brake disc during reverse braking. This issue can be resolved by removing and smoothing the brake pads or replacing them with higher-quality ones. More details are as follows: 1. The automotive brake system, also known as the automotive braking system, functions to: forcibly decelerate or stop moving vehicles as required by the driver; maintain stationary vehicles on various road conditions (including slopes); and stabilize speed during downhill driving. 2. Currently, most domestic automakers use front-disc-rear-drum brake systems for small and medium-sized production vehicles, with some models featuring four-wheel disc brakes. Compared to drum brakes, disc brakes are more technologically advanced, lighter in weight, and offer superior heat dissipation, braking performance, and adaptability to complex weather and road conditions.

How to manually bleed the ABS pump?

abs pump manual bleeding specific practice is to bleed once, then emergency brake 1 to 2 times and bleed again, which can gradually bring the air in the new master cylinder into the pipeline for discharge, and multiple discharges can eventually remove all the air. The role of abs has the following 2 points: 1. Ensure that the vehicle brakes in the shortest distance during braking: At the same time, the vehicle also has steering control ability to avoid obstacles or vehicles in time. The damage of the abs pump will not affect the quality of conventional braking, but the yellow abs warning light on the instrument panel will light up to alert, and it needs to be replaced; 2. Prevent tire lock-up during emergency braking: The ABS sensor on each tire receives the signal and sends it to the ABS computer board, and then the ABS computer board controls the ABS pump to work. The ABS pump pumps oil and releases oil at an extremely fast speed to achieve the anti-lock effect.
