The reliability of the otherwise dominant Red Bull car continues to be an issue, after Sebastian Vettel almost had to retire in Spain a week ago with a split brake disc.

Mark Webber reportedly suffered a brake disc failure during Thursday's practice at Monaco.

The reliability of the otherwise dominant Red Bull car continues to be an issue, after Sebastian Vettel almost had to retire in Spain a week ago with a split brake disc.

"It was quite bizarre as basically the brake on the left hand side stopped working completely and the disc effectively split in half, straight down the middle of the spline," revealed team boss Christian Horner in Monaco.

Vettel said in the Principality that although the precise cause of his Barcelona failure is not known, the team has implemented "a fix" for Monaco.

But although it missed the attention of the rest of the F1 world, Webber suffered a similar problem on Thursday, Finland's Turun Sanomat reports.
