- Mercedes star Lewis Hamilton crashes out of opening day of testing Wednesday
- Problem traced to the hydraulic brake line connecting to the right-rear caliper
- Marussia appoints Brazil's Luis Razia as its second drive for new season
- Razia replaces Timo Glock and will partner Britain's Max Chilton
Lewis Hamilton endured a nightmare start to testing his new Mercedes after driving straight off the track at Jerez on his first day following a hydraulic problem Wednesday.
The 2008 world champion, who left McLaren at the end of last season, was on his 15th lap of timed testing when his car went off the track and hit a barrier of tires.
Hamilton's accident, which prevented him from returning to action, follows teammate Nico Rosberg's disastrous run which was ended by a minor fire Tuesday.
The German's car was found to have been suffering with electrical problems, while Mercedes took to Twitter to give an update on Hamilton's setback.
"Lewis suffered a loss of rear brake pressure, the front brakes enabled him to slow the car but he couldn't avoid the barrier," said Mercedes on Twitter.
