Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to a brake system maintenance auxiliary tool. Background Art

[0002] Disc brakes are widely used in various automobiles as braking devices. Disc brakes include brake discs and brake pads. During the braking process of the car, the brake pads are pressed against the brake disc by external force to generate friction resistance, thereby generating braking force to slow down or stop the car. The brake disc will gradually wear out during use. If the wear exceeds the wear limit, it will have an adverse effect on driving safety. In particular, new energy buses need to brake frequently when driving, and the thickness of their brake discs needs to be measured to confirm whether they exceed the wear limit.

[0003] The existing remaining thickness is usually measured using measuring tools such as vernier calipers, but the wear of brake discs is usually not uniform, which may result in excessive wear of some parts of the brake discs, and multiple measurements are required. At the same time, during the use of the brake discs, rust and accumulated dirt will affect the measurement results of the measuring tools. Utility Model Content

Each bottom rod 9 is vertically installed above the turntable 2. When the bottom end of the pulley 11 contacts the top surface of the turntable 2, the sensor value is in the initial state. It is worth noting that the turntable 2 is driven by an external driving source. While the turntable 2 rotates, the stains and rust on the brake disc can be cleaned by the brush 10 to increase the accuracy of the detection. At the same time, the pulley 11 can reduce friction and avoid wear on the brake disc.
