Matosinhos, Portugal: Toyota's Ott Tanak survived a brake failure at the dust-shrouded Rally of Portugal on Saturday, but clung to a narrow lead over Jari Matti Latvala.
Tanak, an Estonian, who won the last rally at Chile, had to pull over for emergency repairs after the eighth special 20.53km speed test at Vieira do Minho, where he was second fastest.
Tanak, in a Toyota, finished the morning 5.1 sec ahead of Latvala, a Finn driving another Toyota, who won the last two stages of the morning. Briton Kris Meeke, winner of the first stage of the day in a third Toyota, was next 18.4sec back.
Belgian Thierry Neuville was fourth in a Hyundai at 23.7 sec.
While Tanak was left to complain about his brakes most of the other drivers were complaining about the thick clouds of dust on the dirt roads round Porto.
"The dust is very bad. We could do the Paris-Dakar," said Finn Esapekka Lappi, sixth in a Citroen.
"There is just too much of it, I actually had to stop because I couldn't see anything."
Sebastien Ogier said the gaps between cars needed to be increased to allow the dust to settle.
"The shame is that we asked for a four minutes interval yesterday," said the Frenchman, who is 26 sec off the pace in a Citroen.
"Four minutes gap is the minimum but it's working," said Neuville.
