Narrative:
On approach at approximately 4000 ft MSL ATC slowed us to 180 from 220. When I asked the first officer (first officer) pm (pilot monitoring) for flaps 1 almost immediately we got an EICAS message of le (leading edge) flap asym. We broke off the approach and circled for approximately 10 minutes while we worked the QRH. I remained the PF (pilot flying) and the first officer ran the checklist. We managed to get the te (trailing edge) flaps to 20 and setup for a non-normal landing. The fas (flight attendants) were briefed; a message was sent thru ACARS to [maintenance] and dispatch. [ATC was advised] and the fire trucks were asked to be standing by. Our approach speed was 172 KIAS; however the low speed yellow band was right at that speed; so I elected to fly at 175 to 180 KIAS. We briefed the approach and flew the ILS to runway 25L. An uneventful landing was made using autobrakes 3 and full reverse. We taxied to the [gate] with minimal brake temp rise; one wheel on the right truck showed 6 by the time we left the (aircraft); the others were at 5. I floated a bit on touch down due to the sight picture; speed; and darkness; but managed to exit just past midfield. All in all I think the first officer and I managed the [situation] well with great CRM (crew resource management); communications and teamwork. The first officer did an excellent job throughout the incident.

Title: B757 Captain reported receiving an EICAS message LE FLAPS ASYM on approach.
Narrative: On approach at approximately 4000 ft MSL ATC slowed us to 180 from 220. When I asked the FO (First Officer) PM (Pilot Monitoring) for Flaps 1 almost immediately we got an EICAS message of LE (Leading Edge) FLAP ASYM. We broke off the approach and circled for approximately 10 minutes while we worked the QRH. I remained the PF (Pilot Flying) and the FO ran the checklist. We managed to get the TE (Trailing Edge) flaps to 20 and setup for a non-normal landing. The FAs (Flight Attendants) were briefed; a message was sent thru ACARS to [maintenance] and Dispatch. [ATC was advised] and the fire trucks were asked to be standing by. Our approach speed was 172 KIAS; however the low speed yellow band was right at that speed; so I elected to fly at 175 to 180 KIAS. We briefed the approach and flew the ILS to RWY 25L. An uneventful landing was made using AUTOBRAKES 3 and full reverse. We taxied to the [gate] with minimal brake temp rise; one wheel on the right truck showed 6 by the time we left the (Aircraft); the others were at 5. I floated a bit on touch down due to the sight picture; speed; and darkness; but managed to exit just past midfield.
