Narrative:
We departed msp for slc. Climbing through 5000 ft the so said we had 2 'B' system hydraulic boost pump lights, zero pressure and normal quantity. We ran the red bordered checklist for the emergency and I called for the expanded portion of the procedure. I had the first officer level the aircraft at 7000 ft and inform ATC to keep us in the local area and to advise them of a possible problem. The so then informed me that he was missing 10 pages from the hydraulic section and those pages covered our procedure. I called our dispatch and described our situation. We decided to return to msp. And I had our dispatch call to our training department and have a check pilot read our procedure to us over the radio. We accomplished our emergency procedure in this manner. We declared an emergency and I kept the flight attendants and passenger informed. We flew an uneventful approach and landing using a backup braking system to stop the aircraft. The hydraulic failure was caused by a leak in the normal braking system.

Title: A B727 ON CLBOUT DECLARED AN EMER AND DIVERTED DUE TO COMPLETE LOSS OF 'B' SYS HYD PRESSURE WITH NORMAL QUANTITY INDICATIONS.
Narrative: WE DEPARTED MSP FOR SLC. CLBING THROUGH 5000 FT THE SO SAID WE HAD 2 'B' SYS HYD BOOST PUMP LIGHTS, ZERO PRESSURE AND NORMAL QUANTITY. WE RAN THE RED BORDERED CHKLIST FOR THE EMER AND I CALLED FOR THE EXPANDED PORTION OF THE PROC. I HAD THE FO LEVEL THE ACFT AT 7000 FT AND INFORM ATC TO KEEP US IN THE LCL AREA AND TO ADVISE THEM OF A POSSIBLE PROB. THE SO THEN INFORMED ME THAT HE WAS MISSING 10 PAGES FROM THE HYD SECTION AND THOSE PAGES COVERED OUR PROC. I CALLED OUR DISPATCH AND DESCRIBED OUR SIT. WE DECIDED TO RETURN TO MSP. AND I HAD OUR DISPATCH CALL TO OUR TRAINING DEPT AND HAVE A CHK PLT READ OUR PROC TO US OVER THE RADIO. WE ACCOMPLISHED OUR EMER PROC IN THIS MANNER. WE DECLARED AN EMER AND I KEPT THE FLT ATTENDANTS AND PAX INFORMED. WE FLEW AN UNEVENTFUL APCH AND LNDG USING A BACKUP BRAKING SYS TO STOP THE ACFT. THE HYD FAILURE WAS CAUSED BY A LEAK IN THE NORMAL BRAKING SYS.
