>>There's a *lot* of discussion of this on rec.autos.makers.honda. Modern cars have been shipping with thinner and thinner brake rotors, as a way of saving weight and improving EPA fuel economy numbers. Rubbish, I'd say, what they're trying to save is unsprung weight, not overall weight for fuel consumption If indeed they are using thinner barke disc, which surprises me greatly! >I've also heard a theory that it's caused by sitting with your foot on the brake after heavy braking. (The theory being that the rotor cools differently where it's clamped by the caliper.) Personally, the only warped rotor I've had was done in by a draggy caliper, so heating was definately the culprit there. This can definitely warp the discs, keeping foot on brake after a high speed braking session, or multiples thereof, don't forget they're glowing red after a a few fast roundabouts (90 - 40), 90 - 40 and then 90>0 in a 1 ton vehicle (and if you have roundabouts there.) |
