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.

From May 9th to May 9th in Zhaoqing, a 66-year-old man from Gaoyao, Guangdong Province, went missing for 10 days. He had already been searched by more than a thousand people and was still missing.
According to Mr. Wu, an old man's son, his father picked wild vegetables from the nearby Xiangshan Mountain in the morning of April 30. When he was not seen back at 12 o'clock that same day, he and several relatives searched and found his father's bicycle, straw hat, and hand in the mountain hut in the middle of the mountain. Sleeve, but the sickle, radio, and yellow snakeskin bag he carried with him disappeared.
Later, including the elderly relatives, zealous citizens, "alien", forest firefighters, police and so on more than a thousand passengers, even sent out police dogs, carpet-type search several times still results.
On the evening of May 2nd, the local netizen Hou Lang sent a help poster for “Looking for People on the South Shore of Xiangshan Mountain†at the local forum. Immediately, thousands of people gathered around and a group of outdoor enthusiasts joined the search and rescue team to look up.
It is understood that Xiangshan is located in the south of Chenkou Village, Gaoyao Nanan Town. It is 362 meters above sea level and covers an area of ​​more than 6,000 mu. It is named because the mountain resembles a trunk. The forest is deep and dense, mainly in the primary secondary forest. The forest coverage rate is over 91%. .
Mr Ng said that at the time he suspected that his father might have gone to a relative or friend, but after contact he found nothing. He said he suspected that his father had been trafficked. A few days before the accident, a strange man came to smoke his father and he was rejected by his father.
Li Weihong, deputy director of the Gaoyao Nanan Police Station, denied Mr. Wu’s statement. He believes that the old man did not carry valuables without money. The traffickers should not climb to the mountains to find old people to sell.
Li Weihong said that although Xiangshan is not high, it is full of lush vegetation. When the weather is hot, the elderly are prone to heat stroke. If the old man falls in the cave under the vegetation, it is hard to find, and he thinks that the elderly are still rated on the mountain. Li Weihong said that he will conduct investigations and find old people as soon as possible. Finish
