Narrative:
We (aircraft X) were cleared on the FMS visual runway 28R sfo, assigned 180 KIAS, following a B757 in front of us for the same approach. Approach control vectored a brasilia (aircraft Y) for visual approach to runway 28L. The brasilia was at 3600 ft. Approach control asked if we had the brasilia visual. When we acquired the brasilia visually, he was at our 9 O'clock position, 1000 ft above. The captain said he would not be able to keep the brasilia in sight because we would pass him. Approach said that no matter what aircraft he sequenced us with, we would be faster. The request for this approach is that the B757 or larger aircraft cannot pass another aircraft on the visual approach. Approach control at that point vectored us off of the approach. I believe a procedural error on approach control's part caused our go around.
Original NASA ASRS Text
Title: O90 ISSUES GAR TO B757 FLC WHEN THEY ADVISE THEY CANNOT KEEP TFC ABOVE AND TO THEIR L IN SIGHT WHILE CONDUCTING AN SFO FMS VISUAL APCH.
Narrative: WE (ACFT X) WERE CLRED ON THE FMS VISUAL RWY 28R SFO, ASSIGNED 180 KIAS, FOLLOWING A B757 IN FRONT OF US FOR THE SAME APCH. APCH CTL VECTORED A BRASILIA (ACFT Y) FOR VISUAL APCH TO RWY 28L. THE BRASILIA WAS AT 3600 FT. APCH CTL ASKED IF WE HAD THE BRASILIA VISUAL. WHEN WE ACQUIRED THE BRASILIA VISUALLY, HE WAS AT OUR 9 O'CLOCK POS, 1000 FT ABOVE. THE CAPT SAID HE WOULD NOT BE ABLE TO KEEP THE BRASILIA IN SIGHT BECAUSE WE WOULD PASS HIM. APCH SAID THAT NO MATTER WHAT ACFT HE SEQUENCED US WITH, WE WOULD BE FASTER. THE REQUEST FOR THIS APCH IS THAT THE B757 OR LARGER ACFT CANNOT PASS ANOTHER ACFT ON THE VISUAL APCH. APCH CTL AT THAT POINT VECTORED US OFF OF THE APCH. I BELIEVE A PROCEDURAL ERROR ON APCH CTL'S PART CAUSED OUR GAR.
