![]() ![]() Consider the dragster - these have thin rotors with a zillion drilled holes - it works because they only apply the brakes once and then have ample time to allow them to cool off. So there's the dilema - if you reduce the mass you reduce the ability to hold AS MUCH heat. A rotor/drum with MORE mass will momentarily absorb more heat energy. At each application it absorbs heat - the frequency of application (heat induced) has to be allowed to dissipate or you will eventually heat soak your system. After contemplating why here's what I rememeber: Your brake rotor/drum is a heat storage device. ![]() ![]() What you'll notice (I think) is that you'll see alot more modified rotors that are slotted instead of drilled or at least slotted to reduce the number of drilled holes. Look back a few years ago when people first started to drill brake rotors and compare that with what we see today. The term "safer" can mean a lot of things to different people under different circumstances. ![]()
