Preventing warped disks?

[GrinningGSer]

I vaguely remember reading somewhere... that after aggressive heated braking, you should avoid holding the bike with the hot pads pressed hard in one position against the disks.

Any truth or logic in that ?

Oh yes, absolutely...! A brake pad applied to a hot brake disc will act as a localised heat sink and lead to differential cooling of the disc which could result in cracking or warping. If you ever get into doing much track time in a car, you'll find that track cars tend to have their handbrake disabled for that very reason. Even those people driving road cars on track days will, if they're smart, not use the handbrake in the pit lane and will chock the wheels.

Yep, I'd second that.

I've seen it loads on Range Rovers... You know, heavy car, heavy breaking, sitting at lights with foot on brake (coz it's an auto) and hey presto - Warped disks.

Here's an article about pads and discs FWIW,
