Fensport Tip: Always replace brake discs in pairs and make sure the hub faces are clean and free from rust or defects. A "smear" of copaslip or similar, should be applied between disc and hub flange to help prevent any future rust build up. New brake pads should also be fitted and the manufacturer's bed in procedure followed. This will ensure you get the best possible lifespan for your new brake discs & pads.
