After a strong drive to fifth in the first race of the AutoGP World Series season opener in Monza on Saturday, brake problems forced Narain Karthikeyan to retire on the first lap of race two on Sunday.
Karthikeyan recorded the third fastest lap of race one during his drive from the back of the field but front brake failure on his Zele Racing car meant he was unable to take advantage of starting race two from fourth in wet conditions.
"They changed the master cylinder on the brakes last night after problems arose," Karthikeyan told HT over the phone from Italy. "I started to detect problems on the reconnaissance lap and then had no front brakes at the start of the race and had to retire.
"It was a shame, because a podium at least looked easy as my teammate (Luciano Bacheta) managed to finish second but what can you do?"
Karthikeyan had signed to race just in Monza, but admitted that a final decision to compete in the rest of the series will be evaluated and taken in the coming week.
"I would like to keep driving single seaters and this is a pretty competitive series," said Karthikeyan. "But there are some other options so I'll have to just wait and see for now."
