Yes, I believe so. This was because the 1950's era engines still had a long spool up time. The solution was to put as much drag on the aircraft as possible, so that you could carry as much power as possible on approach, thus not needing to worry quite so much about spool up times. Need speed? Close the speed-brakes. Instant speed, without having to wait for the engine(s) to wind up.
1:04 here clearly shows the speed brakes deployed prior to runway landing in the FJ2, the Navy equivalent of the F-86 Sabre.

The same procedure was continued even after engines got more reliable and faster on the uptake. Good habits die hard? Either way, I'm sure it was difficult to unlearn having power available when looking at that postage stamp of a flight deck, especially at night.
As an aside, I know a retired 747 guy who says that's exactly what they did on approaches. Everything out (gear, flaps, the works), THEN start your approach. Their rationale was that if you had everything out beforehand, then you weren't changing the configuration, and thus flying characteristics, of the aircraft mid-way through an approach. Solid reasoning.
Hmmm, crash barrier. An excellent suggestion, ghostdog688.
