There are TWO reasons our customers love Redstuff, First because they are the lowest dust pad we have encountered by reducing dust by 60-90-percent. Plus the minimal dust you see is very easily removed with a simple sponge wash as it contains no steel fibre particles as in ALL OTHER pads. Second they brake like an alligator right from cold (as good as Original pads or better) and just get better as they heat up.This material is a Synthetic Fiber based brake compound enhanced with ceramic particles. If you have previously tried EBC redstuff (pre-ceramic compound) this material is light years ahead. It lasts longer; it brakes better and is quieter. Being a hard wearing pad, bed-in times can be as long as 1000 miles and drivers must be patient until the pad takes up the shape of their disc (brake rotor). This is a truly impressive fast road pad for repeated heavy braking.It emits far less dust than semi-metallic pads and has been proven to stop a passenger car/sedan/sport compact/hot hatch 13 metres quicker than OEM pads from 100mph/160kph. Features EBC Brake-In surface coating which conditions rotor surface and accelerates pad bed-in. Nominal friction coefficient 0.5 with approx. 50-percent dust reduction.Most EBC Red Ceramic pads are approved to ECE R90 brake safety regulation. Low dust EBC Redstuff is a superb pad for fast street use and targets high HP imports, muscle cars and prestige European cars. EBC Redstuff ceramic pads reduce dust emitted by OEM pads by approx 80 percent.
