The drum test brake is to install the friction pad of the Henan truck accessory manufacturer on the surface of the two arc brake shoes, take one end of the brake shoe as the support point, and increase the driving force from the other end to make the brake shoe press towards the inner side of the brake drum and brake. In the hydraulic mechanism pump, the piston rod of the Henan truck accessory manufacturer of the brake master cylinder immediately promotes the brake shoe; In the event of air impact braking, narrow air will promote the rotation of a camshaft to make the brake shoe extend outward. When the brake working pressure subsides, the return torsion spring pulls the brake shoe away from the brake drum, thus eliminating the brake.

Lastly, inaccuracies in urea level sensor readings can delay timely additions of urea leading to dry burning issues; if overlooked over time this could result in damage to the urea system.

As a major auto consumer, China's auto industry has been the largest in the world for 9 consecutive years, and the auto parts market has been expanding.
