Looking at the 10-9A for VABB, I don't see any reference to the runway being grooved.
Whilst using heavy breaking on non grooved wet runways, water under the wheels can turn to steam, which then reverts the rubber to its natural form melting the rubber which obviously greatly reduces breaking effectiveness. That’s what you’re seeing.
