But there were no such problems for defending women's champion Maria Sharapova who eased past Taiwan's Hsieh Su-Wei in just 54 minutes yesterday, surrendering only eight points on serve.
Seven-time champion Nadal dropped the opening set of a Grand Slam for the first time in his career yesterday before he prevailed 4-6 7-6 (7/4) 6-4 6-3 against a player who had lost all four of his previous matches in Paris.
The Spaniard, who before this year had only lost once in 53 outings at Roland Garros, came into the tournament having won six titles in eight finals since he returned from a seventh-month injury lay-off.
It was almost a carbon copy of the tactics employed by Robin Soderling, the only man to beat Nadal in Paris four years ago, and Lukas Rosol, who dumped the Spaniard out of Wimbledon last year.
Brands even led 3/0 in the second set tie-breaker as he appeared poised to deliver the first defeat of a men's champion in the opening round in tournament history.
But Nadal eventually found his rhythm to steady the ship as the 25-year-old German eventually ran out of firepower.
"He played a great match and put me in a tricky situation."
Czech fifth seed Tomas Berdych was the biggest casualty of the day when the 2010 semi-finalist fell to French wildcard Gael Monfils.
Monfils, whose career has been plagued recently by a knee injury, triumphed 7-6 (10/8) 6-4 6-7 (3/7) 6-7 (4/7) 7-5 in a shade over four hours.
