Newbie trainee mechanic at #halfords sprays WD-40 onto my bike brake disc caliper, WD-40 (an oil based lubricant) then drips down my rotors. I stand there in shock horror and watch as he applied brakes, coating my brake pads in WD-40. I then demonstrated to him how he'd just destroyed my brakes and just how dangerous that was!
Can imagine a less experienced cyclist then getting on the bike, cycling to next junction, finding they have no brakes and suffering a fatality 😱
