After a nice initial very light touchdown in the first 3000 feet of the runway; the speedbrakes did not auto deploy and it took me a couple seconds to realize that I had to manually deploy them. This meant that I was delayed getting reverse thrust and manual braking; resulting in me using more than typical braking energy. This was a hot day; 91 degrees; and a high altitude airport. By the time we got to the ramp we had hot brakes of 6 on the left side of the aircraft.We had briefed a higher than normal descent on the approach 3.1 degrees and knew that speed control was very important on final. I had to use speedbrakes several times during the approach to help control speed and I had placed them back in armed. However; after we lowered the gear approximately 10 miles from the airport; the FO had started the landing checklist and they were armed at that time. Then I used the speedbrakes one last time to slow for final flap extension. I am convinced that I failed to return them to armed after this last extension in flight. The result was that it took me a couple of seconds after initial touchdown to manually deploy them and I wasn't able to get into reverse thrust and braking until further down the runway than I would have liked. I also thought I had to exit abeam the landing threshold for another runway; but I could have rolled down to the end (approximately 1000 feet) and used a little less braking than I did.I believe that we should have restarted the landing checklist after I used the speedbrakes; so as to ensure that they were returned to armed. I also think that this shows why it is a good practice to fail the speedbrakes in the sim for annual training; so that we realize quickly that they have not auto-deployed. The Airbus incident in the Philippines is proof of how important this confirmation is!

B767-300 flight crew reported the speedbrakes did not automatically deploy on touchdown at a hot; high altitude airport which resulted in a longer rollout; heavier braking; and hot brakes.
