Talk:Cadence braking

message: I'm a layman with little-to-no interest in cars and barely even have a license, and was looking for a little more technical information about what people really mean when they say this. This article quickly develops into complex language about a technical topic. It would be nice if there were a paragraph in laymen's simple English about the common understanding of the term. 71.238.116.27 (talk) 19:50, 1 October 2019 (UTC)

message: What principle governs the 11% rule? It might be useful to include it here instead of just putting a number.

replies: text: I agree, that would be useful to know. I wrote that figure in the article, based on a number of texts I've read it in, with no further explanation. Intriguing... I guess it's something to do with the maximum shear force that can be transmitted across a compliant medium - intuitively one can imagine that this will be at a maximum for some value of slip between zero and 100%, but why 11% in particular I don't know.

replies: text: That's just a typical figure for a production tire on asphalt. It varies with rubber compound, construction, speed, pressure and the road surface. and probably a few other things Greglocock 05:35, 9 September 2006 (UTC)
replies: text: So would it be fair to change this to "approximately 10%, dependent on factors such as rubber compound, tire construction, speed, pressure and the road surface" rather than quoting a specific figure with no reference? Driver sam (talk) 14:57, 10 June 2008 (UTC)

message: Why is the Commonwealth spelling "tyres" being changed to "tires"? The original article uses "tyres". This should remain. I am reverting the last edit.

message: That thing about timing the braking to the swaying of the car sounds interesting. What is the advantage of doing that? —Bromskloss 00:15, 26 January 2007 (UTC)
replies: text: Sounds reasonable. Thanks for that. What would the difference be between old and new cars, that make this technique useful only on the old ones? —Bromskloss 13:14, 27 January 2007 (UTC)
replies: text:  The shock abosrbers on pre-war cars were not sufficinetly powerful to really prevent the car from pitching for several cycles, so you could time teh pressure on the brake pedal to synchronise with that. By the 60s, if not earlier, this no longer happened, the car would just pitch forward and stay there, under braking. If I remember I'll have a look at some real data and see if that is the case. I suspect that cadence braking is an old skill that 'everyone' has heard of, but no-one uses any more. Greglocock 22:43, 27 January 2007 (UTC)

replies: text: The argument in that website is based on a false premise. The data shown for grip vs slip bears no strong resemblance to real world data as the peak s approached and exceeded. Threshold braking will stop the car in a shorter distance than locked wheels. Cadence braking may or may not. I removed that section as it is (a) wrong and (b) encourages dangerous behaviour (locking wheels) and is (c) poorly written and (d) unreferenced.

thread_title: Myth

message: When I took a motorcycle safety course we were taught to lightly apply/release (pulse) the rear brake (foot brake) when braking. We did not do it in an attempt to stop more quickly. In fact, we do not even attempt to brake at this point in time. Rather...
The pulsing was intended to flash the motorcycle's rear brake light to make the action more visible to drivers behind the motorcycle. The pulsing takes advantage of a human's ability to easily detect something that is changing (the flashing brake light), as opposed to a brake light that is steady off or steady on. If a trailing driver looks away when a motorcyclist applies the brake, the trailing driver may miss the change in the brake light state and rear end the motorcyclist.
After the driver behind us was alerted by flashing our brake light, we would then perform a the cadence braking using both front and rear brakes. The front brake would stop the bike, the rear brake light would continue to flash.
Here's a forum discussion about the technique: Flashing brake lights. And another about flashing the brake lights in general: Why do some motorcycle’s brake lights flash?
It may be a good idea to discuss the technique in the article.
