Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a brake disc flatness detection tool. Background Art

[0002] Simply put, a brake disc is a round plate that rotates as the car moves. The brake caliper clamps the disc, generating braking force. When you apply the brakes, it's the caliper that slows or stops the car. Disc brakes offer superior braking performance and are easier to maintain than drum brakes.

[0003] Brake discs, as core components of automotive braking systems, wear over time. Therefore, timely and accurate testing of their flatness is crucial. Currently available brake disc flatness testing tools, such as the utility model patented with patent number CN221666840U, are designed to simultaneously assess both sides of a brake disc, as both sides wear during braking. However, these devices only test one side. This means that to fully assess the condition of the brake disc, the operator must remove the disc from the vehicle and flip it over to examine the wear on the other side. This process is time-consuming and increases operational complexity. Furthermore, these devices cannot effectively measure the flatness of the brake disc from the center to the edge. Brake disc flatness not only reflects surface uniformity but also encompasses the gradient from the center to the outside. Failure to comprehensively assess this flatness dimension can lead to misjudgment of the brake disc's actual condition, compromising driving safety. Utility Model Content
