Does CJ7 with power brakes have brake pedal return spring?

Hi everyone.
This has been posted before but there wasn't a definitive answer
I have a 1982 CJ7 with power brakes. There is no brake pedal return spring fitted.
The workshop manual and some photos on the internet show the spring but some people suggest that the spring is not necessary with power brakes.
Does anyone know which is correct?
Thanks

Every brake pedal has a return spring. Doesn't matter if it's power or manual.

Power Brake unit has a internal spring

Thanks 1949er I think you might be right
I've just reassembled the pedals and power brake unit and it seems that the spring is not necessary as the internal spring in the power unit pushes the pedal so that it is exactly in line with the clutch pedal. It returns to the same place aligned when pushed

Here's a pic of the aligned pedals without a spring.

I had to put one on my '84 (not sure there was one that broke/fell off or not... but there was a place for it). Without it, the pedal wouldn't return enough to trigger the brake light switch (my brake light would stay on most of the time).
