How many brake pads does a car have?
2 Answers
A car has 8 brake pads. Here are the details: Distribution of car brake pads: 2 for the front wheels, 2 for each wheel, totaling 4. For the rear wheels, there are 2 wheels with 2 pads each. That makes 2 pads per wheel and 4 pads in total, resulting in a combined total of 8 brake pads. Material of brake pads: They are generally composed of steel plates, bonded heat insulation layers, and friction blocks. The steel plates are coated to prevent rust, and the coating process is monitored using an SMT-4 furnace temperature tracker to ensure quality by checking the temperature distribution during coating. The heat insulation layer is made of non-heat-conductive materials to provide thermal insulation. The friction block consists of friction materials and adhesives, which are pressed against the brake disc or drum during braking to generate friction, thereby achieving the purpose of slowing down or stopping the vehicle. Due to friction, the friction blocks gradually wear out. Generally, the lower the cost of the brake pads, the faster they wear.
It depends on the car model! Most regular family sedans have two brake calipers each at the front and rear, with each caliper paired to one set of brake pads. That adds up to 4 brake pads in total (4 pads for front wheels, 4 pads for rear wheels). But be aware, some cars use drum brakes for the rear wheels - those components are called brake shoes, not brake pads. When I replaced the rear brakes on an old Nissan Sylphy last time, I realized only the front wheels used pads while the rear had two drum brake assemblies. Don't foolishly ask the repair shop why there are four fewer pads!
