Given that conventional disc brakes operate by converting kinetic energy into heat via friction of two metals, – the disc and the pad – you’d reckon that too much braking may deal considerable damage to either part. With brake disc warping, uneven pad deposits, or outright thinning of rotors becoming the usual wear and tear issues for most cars you’d just have to wonder: Just how far can a brake system go till it actually goes kaboom?
Well, it appears the folks from Beyond The Press wanted to find out for sure – and they’ve been kind enough to record the results of their little experiment. The rather long 12-minute clip below documents their use of a run-down Ford Fiesta as the experiment’s base.
By jacking up one wheel in front and sending all power to it via an open differential, they start rolling the car in gear at high revs while simultaneously stepping on the brakes to generate continuous friction on the brake system.
Following the rather spectacular result of their experiment, several angles including a slow-motion clip as well as a thermal range version of the event were also shown to clearly indicate just how hot the brakes were running.
