Narrative:

Departed mem at XA02 local. During flap retraction, so noted loss of hydraulic 'B' pressure and blinking low pressure lights. We complied with all applicable checklists and requested/returned to mem for visual approach and landing. We did request equipment to be standing by since los of hydraulic 'B' (which normally pwrs brakes) would require (by checklist) using brake interconnect to allow system 'a' to power the brakes. We did not declare emergency. Landing was normal (for the conditions).

Original NASA ASRS Text

Title: A B727-200 ON INITIAL CLB DIVERTED DUE TO LOSS OF 'B' HYD SYS PRESSURE AND QUANTITY. CAUSE UNKNOWN.

Narrative: DEPARTED MEM AT XA02 LCL. DURING FLAP RETRACTION, SO NOTED LOSS OF HYD 'B' PRESSURE AND BLINKING LOW PRESSURE LIGHTS. WE COMPLIED WITH ALL APPLICABLE CHKLISTS AND REQUESTED/RETURNED TO MEM FOR VISUAL APCH AND LNDG. WE DID REQUEST EQUIP TO BE STANDING BY SINCE LOS OF HYD 'B' (WHICH NORMALLY PWRS BRAKES) WOULD REQUIRE (BY CHKLIST) USING BRAKE INTERCONNECT TO ALLOW SYS 'A' TO PWR THE BRAKES. WE DID NOT DECLARE EMER. LNDG WAS NORMAL (FOR THE CONDITIONS).
