Force India is "demanding the FIA review Formula 1's radio restrictions after being unable to inform Sergio Perez of the brake issue behind his last-lap Austrian Grand Prix crash," according to EUROSPORT. Deputy Team Principal Bob Fernley claims "he was informed by race control not to pass on information to both Perez and Nico Hulkenberg regarding their brakes." Perez's failed on the last lap, six laps after Hulkenberg "had to retire his car due to a similar problem." Fernley said, "We've got to look at the radio communication bit because we were not allowed to tell the drivers their brakes were critical. It's a bit worrying. It seems a bit silly putting a halo on a car but not being able to tell a driver his brakes are about to go." Mercedes Motorsports Dir Toto Wolff "feels tweaks are needed." Asked if "he was frustrated" with the radio ban, Wolff replied, "The FIA's not in an easy position because what is the limit? Teams might easily abuse it, and under the title of safety try to communicate with the drivers. My opinion is we probably went a little too far in what is restricted" (EUROSPORT, 7/4).
