Engineered for Australian operating conditions, these Ferodo Rear Brake Pads suit Audi A4 models built from 2018 to 2021. The friction compound is a Ceramic formulation that gives consistent bite from cold and resists fade under towing, hills and stop-start traffic. Nominal friction thickness is 18mm, matched to the original caliper piston area and rotor swept face. Underlayer construction insulates the backing plate from heat and protects the caliper piston seals. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Sold new with 36 Months warranty cover and full technical support.
