Why does the Cayenne make a noise when braking?
2 Answers
It may be due to the sound produced when hard spots on the brake pads rub against the brake disc. It is recommended to check the rear wheel braking system. Relevant details are as follows: 1. Porsche Cayenne: The Porsche Cayenne first appeared at the Geneva Motor Show in early 2002 and is divided into five categories: Cayenne, Cayenne-S, Cayenne-Turbo, Cayenne-Turbo-S, and Cayenne-GTS. Born from Porsche, a company renowned for producing supercars, the Cayenne, despite being an SUV, inevitably carries many sports car traits. 2. Body dimensions: In terms of appearance, the Cayenne's headlights and radiator grille maintain Porsche's traditional style. The car is 1940mm wide but only 1690mm tall. The ground clearance is 273mm, with a maximum approach angle of 32 degrees. The long travel of the shock absorbers enhances off-road performance.
A few days ago, I worked on a Cayenne where the customer complained about a squeaking noise when braking. This issue is quite common in luxury cars. Usually, it's caused by impurities in the brake pads or high metal content, which creates friction noise when braking. New cars might have some break-in noises initially, but these should disappear after normal driving for a while. If the noise persists, it's necessary to carefully check whether the rotor surface is worn or uneven, as dust or sand trapped in the brakes can also cause squealing. I recommend getting the brake system inspected at a shop as soon as possible—don't ignore safety risks. The Cayenne's brake components are expensive but of excellent quality, and regular cleaning and maintenance can prevent issues. Replacing them with genuine brake pads can solve most problems. Avoid using aftermarket parts to save money, as they may cause more noise or damage.
