The invention discloses a device and a method for testing brake wear particulate matter emission. The device comprises a pin-disc type friction testing machine, a closed air chamber and a cooling air conditioning system, wherein the closed air chamber is surrounded by particulate matters generated by friction of the pin-disc type friction testing machine; the cooling air conditioning system is used for inputting cold air with preset temperature, humidity and flow into the closed air chamber through an air inlet pipe; the particulate matter emission testing equipment is used for sampling the same sampling section in the exhaust pipe connected with the gas outlet of the closed gas chamber so as to detect the emission quality and quantity concentration of particulate matters generated by friction; the gas flow sensor is used for detecting the gas flow in the exhaust pipe; a friction pin of the pin-disc type friction testing machine is made of a brake friction plate material, and a friction disc material is made
