Title: Disc brake rotor. Post by: ROD on May 05, 2009, 05:31:11 PM Are 'bike brake discs made of any special type of steel? Is it ok to use a disc made from stainless,say 6mm thick?
Thanks (for a parking brake ,not the main brakes) Title: Re: Disc brake rotor. Post by: tbone on May 05, 2009, 06:07:15 PM Purely for a handbrake, to be applied when the vehicle has stopped, then i would say yes, you will get away with it.
Brake discs however are made from a variety of materials including cast iron and hardened steel with a high carbon content, to combat the heat generated from friction. A mild steel compound would not withstand the heat or forces being applied to it. Title: Re: Disc brake rotor.
