Incorrect. The brakes on transport category aircraft are certified to
stop the aircraft on the runway remaining after a rejected takeoff at
the highest speed it would still be on the ground (V1) without using
thrust reversers. Thrust reversers provide little braking at high speeds
anyway.

The brakes *will* stop the plane at V1. Other than that, there may be
problems. The company I work for sells parts for "retriever kits." They use
these kits to recover aircraft after they deploy the brakes during an
aborted takeoff. The heat from the brakes soak into the tires and cause
various problems.

Note 4.3.4, time to tire failure after emergency braking operation is about
12 to 15 minutes.
