Why does the Q5's brakes squeak?

[StVera]

Q5 brake squeaking is a common issue, and currently, there is no suitable solution. It is said that the main reason for the "squeaking" is due to the car's high power—the heavier the vehicle and the faster it goes, the higher the required friction coefficient. The brake noise is caused by the friction between metal particles in the friction material and the brake disc, and this noise does not affect safety. Below is some relevant information about the Q5: 1. The new Audi Q5 still comes equipped with the EA888 2.0-liter turbocharged direct-injection engine. The entry-level 35TFSI model is the low-power version, with a maximum power of 132kW at 4000-6000rpm and a peak torque of 320N·m at 1500-3900rpm. 2. The other five 40TFSI models are high-power versions, with a maximum power of 155kW at 4300-6000rpm and a peak torque of 350N·m at 1500-4200rpm. Except for the entry-level 35TFSI, which comes with a 6-speed manual transmission, the other five 40TFSI models are equipped with an 8-speed automatic transmission.
