Yes, about 30 years ago at LGW on an Air Europe 737 and I reckon we were about 80% through the take-off roll. It made me realise just how powerful those brakes are as the deceleration was pretty impressive and this would also have been with a reasonably full fuel load as the flight was around 3 hours.

Also had a rejected take-off in the back seat of an F4 Phantom out of Boscombe Down in the early 80s when a fire warning went off. That also came to a stop pretty quickly and the test pilot asked for immediate ground support because of the need to vacate the plane quickly due to brake overheat causing a further fire risk
