(CNN) -- 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.

"Update from Jerez, we have traced the problem to the hydraulic brake line connecting to the right-rear caliper."
