Brake pads convert the kinetic energy of
the vehicle to thermal energy through friction. Two brake pads
are contained in the brake caliper, with their friction surfaces facing
the rotor. When the brakes are hydraulically applied, the
caliper clamps or squeezes the two pads together onto the spinning rotor to
slow and stop the vehicle. When a brake pad heats up due to contact with
the rotor, it transfers small amounts of its friction material onto the
disc, leaving a dull grey coating on it. The brake pad and disc (both now
having the friction material), then "stick" to each other, providing
the friction that stops the vehicle.
In disc brakes, there are usually two brake pads per disc rotor.
These are held in place and actuated by a caliper affixed to the wheel hub
or suspension upright. Racing calipers, however, can utilize up to
six pads, with varying frictional properties in a staggered pattern for optimum
performance. Depending on the properties of the material, the weight of the
vehicle and the speeds it is driven at, disc wear rates may vary. The brake
pads must usually be replaced regularly (depending on pad material) to prevent
brake fade. Most brake pads are equipped with a method of alerting the driver
when this needs to be done. A common technique is manufacturing a small central
groove whose eventual disappearance by wear indicates the end of a pad's
service life. Other methods include placing a thin strip of soft metal in a
groove, such that when exposed (due to wear) the brakes squeal audibly. A soft
metal wear tab can also be embedded in the pad material that closes an electric
circuit when the brake pad wears thin, lighting a dashboard warning light.

The shortest period of use in the third filter is the oil filter of the garbage truck, which is usually 5000 to 10000 km and needs to be replaced once. The working condition of the oil filter is directly related to whether the engine of the garbage truck is working properly, because it is the metal wear debris that is generated during the combustion process of the garbage truck and mixed into the engine oil, the carbon particles and the gum produced gradually by the engine oil, etc. Impurities are filtered out. These metal debris, carbon particles, colloids and other impurities will not only accelerate the wear of the engine parts of the garbage truck, but also cause blockage of the lubricating oil road of the garbage truck engine.
Most of the engines used by Cheng Li's garbage trucks are spin-on oil filters, which are disposable filters. We need to replace the garbage truck oil filter when we replace the oil. Affect the quality of garbage truck lubricants.
The oil filter used in garbage trucks is characterized by good sealing and easy disassembly. However, before installing a new oil filter on garbage trucks, a layer of engine oil should be applied to the rubber gaskets to improve the sealing performance and prevent them from being installed. Damage to the seal, and we also need to add oil to the oil filter to make the garbage truck engine recover as soon as possible. ?
The most complicated way to replace the three filters is garbage truck fuel filters. Because gasoline will inevitably contain some impurities and moisture during the production, storage, transportation and filling process, these impurities will be brought into the garbage truck fuel supply system and garbage truck engine cylinders, which will cause the garbage truck cylinders to accelerate wear and tear. Blocked oil roads, damaged garbage truck nozzles and other phenomena.
Cheng Li's garbage trucks are fuel filters that are disposable non-removable paper filter fuel filters. The garbage filter has inlet and outlet arrow marks for replacement. If the garbage filter is installed in the fuel line, we call it the external filter; if it is installed in the filter installed in the fuel pump and the fuel tank, we call it the internal filter.
Garbage truck engine life is directly related to the service life of the garbage truck. Overloading, high-speed driving, and wrong driving all reduce the performance and lifespan of the garbage truck engine. The unclean interior of the garbage truck engine is the biggest damage to the garbage truck. The only way to prevent harmful particles from entering the garbage truck engine.
Garbage truck three filter is what we often say air, oil, fuel filters. Garbage truck three filters filter the engine air, oil and gasoline to protect the engine. At the same time, it can also ensure the efficiency of garbage truck engines. Garbage trucks have a good working condition and are also related to garbage truck fuel consumption. Here we introduce the garbage filter replacement method:
