Brake linings, asbestos free brake linings, semi metal brake linings, explosion-proof brake linings, steel backed adhesive linings, Disc brake linings, clutch discs, etc. Suitable for ports, steel cranes, tower cranes, engineering machinery, drilling machinery, hydraulic machinery, and the production of various materials of automotive and power vehicle brake pads. Asbestos-free brake shoes are a new generation of brake friction materials. Traditional asbestos brake materials pose a serious threat to human health and are gradually phased out products. The new asbestos free material not only poses no harm to the human body, but also has superior performance indicators compared to asbestos brake materials. The product is mainly used for brake pads, linings, etc. of various lifting machinery and other brakes.

There are two types of brake pads: one is made of asbestos rubber steel wire mesh material for the brake band, and the other is made of asbestos resin. The non asbestos brake pad and brake pad use two types: plug-in and riveted, which are safe and reliable, convenient to replace, and fast.

Brake drum. The working surface of the inner wall of the brake drum will experience severe wear after long-term braking use. Its roundness has changed, and the coaxiality between its inner working surface and its installation positioning surface has also changed. As a result, various faults may occur when the car is braking, such as poor braking effect, noise, vibration, etc. Therefore, timely repairs must be carried out. As for the repair method to be used, it can be determined based on the wear and tear situation. When the wear of the inner wall working surface is not very severe, and the changes in its roundness and coaxiality of the positioning reference are not too large, the method of honing can be used to solve it. Usually, the roundness of the inner wall working surface reaches 0 5 mm, with a coaxiality of 0 2 mm requires hole lining repair. The common damages of brake drums in operation include wear and grooving of the friction surface, as well as deformation and loss of roundness. These damages will directly affect braking efficiency. Therefore, the working surface of the brake drum must be flat and smooth, and have good contact with the friction plate. Minor scratches, small grooves, and slight mechanical damage on the outer shoulder are allowed without affecting the quality of use. The roundness error can be measured with a dedicated bow inner diameter gauge, and the radius error exceeds 0 13 mm, or severe grooves caused by exposed shoe rivets, should be polished on a lathe or brake drum polishing machine according to the actual wear situation. If the brake drum of a car experiences cracks, severe deformation, or wear, and the inner diameter exceeds the limit, it should be replaced. The repaired brake drum should undergo a static balance check, and its static imbalance should not exceed 200 g • cm. When grooves appear on the working surface of the brake drum, or its roundness and radial total runout (i.e. the deviation from the hub axis) exceed the usage requirements, it will seriously affect the braking efficiency of the car and should be repaired in a timely manner. General requirements for brake drum lining: Position the outer ring of the wheel hub bearing (to ensure coaxiality after lining). After lining, the inner diameter of the brake drum shall not exceed the basic size by 4 mm, and the cylindricity shall not exceed 0 10mm, with a radial runout of no more than 0 10 mm. If the inner diameter of the brake drum is worn beyond the specified limit, it should be replaced with a new one.

2. Brake shoe friction lining. When the brake shoe friction lining is severely worn, or the surface of the friction lining is severely contaminated or burned by oil, a new shoe should be replaced. When replacing, both left and right wheels must be carried out simultaneously, and friction linings of the same manufacturer, brand, and material must be selected and installed. When the new shoe after replacement does not fit well with the brake drum, it should be ground until it meets the requirements. The general requirement is to ensure that the bonding area between the shoe and the brake drum is greater than 60% of the total area of the friction lining. The brake shoe return spring should be checked for its free length. If it exceeds 5% of its standard length or if there is a gap between the coils, it should be replaced. If the brake shoe tendon is warped or deformed, it will interfere with the bolt (nut) of the brake clearance adjustment device, and with the groove of the brake cylinder piston and brake support plate. This will affect the free opening and return of the brake shoe friction lining assembly. If this situation occurs, it can be repaired using cold correction methods. If the brake shoe base plate undergoes deformation, it can also be repaired using cold correction methods. For cracks in the brake shoe bottom plate welds caused by deformation or other reasons, the verticality shall not exceed 0 At 25 mm, welding repair and correction can be carried out; If the damage is too severe and cannot be repaired, it should be replaced. The tension spring of the brake shoe must maintain a certain amount of elasticity. If there is a severe decrease in elasticity, it often causes the brake tendon to detach from the groove of the brake support plate and become stuck, causing the brake to not be released. Therefore, it is necessary to replace springs with severely reduced elasticity in a timely manner. During driving, due to the frequent application of braking to the car, the brake drum and brake shoe friction plate will experience varying degrees and types of wear or deformation. To ensure driving safety, it is necessary to repair it. Within the allowable range of repair dimensions, the brake drum is often processed using ordinary lathes or specialized machine tools. At present, there are two ways to process brake friction pads. One is to remove them from the vehicle and fix them on a specialized fixture for grinding or turning. Although this method can improve processing quality, save labor hours, and is suitable for division of labor and flow operations, due to the limitations of current overhaul and maintenance technology in China, the brake shoes processed in this way often cannot meet the assembly requirements of vehicles, thereby affecting braking efficiency in the early stages of driving. Another method is to machine the brake shoe friction plates on the machine. As it is positioned and processed based on actual conditions, it is more suitable for the assembly requirements of the brake. Although this method requires more labor, it is flexible and convenient for general repair shops or workshops to use. The equipment processed using the second method is mostly self-made, which can be divided into integral and separate types from the perspective of the overall structure. The latter is to install the moving tool head and feed mechanism on a small car, while the tool holder and positioning device are fixed on the front or rear axle of the car; The former institutions are installed as a whole on the car. There are two types of integrated brake shoe polishing machines: manual and electric, while the separate types are mostly electric
