9040-355x32 6 Pot Brake Kit Car Full Set For Benz W117 Front

Product Description

Jekit car full set 9040-355x32 brake kit fit for benz w117 front

The braking system shall be maintained every 20000 km.

Brake oil also has a shelf life with other lubricating oils. For safety reasons, it is OK to change brake oil every two years, if it is considered OK after inspection by the 4S store. If there is a slight sound during braking, it is generally not a problem, but if there is an obvious abnormal sound or jitter during braking, it is necessary to carefully check or repair the brake disc (drum) and brake pad.

The disc brake is prone to problems, generally about 50000-60000 km; Drum brakes are prone to problems, generally about 80000 kilometers. Of course, if used properly or of excellent quality, the service life can be appropriately extended.

Main components of braking system

1. Brake disc diameter

The brake disc diameter D shall be taken as large as possible. At this time, the effective radius of the brake disc is increased, which can reduce the clamping force of the brake caliper and reduce the unit pressure and working temperature of the pad. Limited by the rim diameter, the diameter of the brake disc is usually 70% - 79% of the rim diameter. The upper limit shall be taken for vehicles with a total mass greater than 2T.

2. Brake disc thickness

Brake disc thickness has an effect on brake disc quality and temperature rise during operation. In order to reduce the mass, the brake disc thickness should not be too large; In order to reduce the temperature, the brake disc thickness should not be too small. The brake disc can be made solid, or a ventilation hole can be cast in the middle of the brake disc for heat dissipation and ventilation.

What is the material of car calipers?

The material of automobile calipers is wear-resistant and high-strength carbon steel. The hardness of this steel is that it can be used as a brake caliper for a long time without being worn out. Carbon steel is a steel with carbon content less than 1.35% (0.1% - 1.2%), which does not contain other alloy elements except iron, carbon and impurities such as silicon, manganese, phosphorus and sulfur within the limit. The properties of carbon steel mainly depend on the carbon content.
Brake caliper is a caliper device with the functions of decelerating, stopping or maintaining the stopped state of moving wheels. It is generally only used in disc brake system. The working principle of disc brake can be described as a plate. When holding the rotating plate with your thumb and index finger, the plate will also stop rotating. Your thumb and index finger play the role of brake caliper.
