With all of the recent caliper discussions, I got to thinking: has anyone here actually suffered from stock rotors overheating? Street or track? Which calipers? Which MC?
I've personally only ever suffered from brake fade caused by overheating brakes twice, and neither time was in a 914. Once on a Alfa with inboard rear brakes and an overenthusiatic romp along a road with lots of downhill hairpins, the other time on a Mini with drums all round, also on a romp through a (different) set of downhill hairpins. The Alfa was heavy and suffered from bad cooling of those inboard brakes (which had vented rotors), and the Mini just used cheap iron drums (and I was deliberately trying to induce fade). Interestingly, another very similar Alfa that was much lighter (400lbs or so, from lighter body stampings and a four instead of a six) never suffered from fade despite solid rotors at both ends, on the same roads that would cook the brakes on the later, heavier car. Much as I approve of the idea of good strong brakes, I wonder just how necessary big, heavy, expensive vented rotors really are on the car (at least with stock or near-stock power). |

Yes, on my 914, during two different DE events at Putnam Park. Both days were very warm. I have 911M Calipers on the front w/solid rotors, stock rears, 19mm master cyl, DOT 4 fluid. The first time was during my first DE. I had heard about brake fade but never experienced until going into turn 7 rather fast, press the pedal and it goes to the floor. In my rookiness, I end up trying to make the turn anyways, and end up spinning....
The second time during a different DE, same track, was after putting new Hawk pads all the way around. I notice the fade before it gets too bad and I can allow things to cool some without getting into any trouble. |
