From what I can tell, the automatic transmission ones DO NOT, but the manual transmission ones DO.   The pedal setup I put in the Parisienne has the return spring on the brake pedal.    Same with the pedal setup I pulled out of a 70 Impala as seen below (it's the orange spring, in the rear view you can see it hooked around the brake pedal).  I sold this set on ebay a couple years ago.

I believe what both of you are missing here is that only the non power assisted brakes got the return spring... power assisted brakes never, as far as I have seen, never got the spring... Clint, the pic you have posted, it has the cheaper pads on the pedal... I would summize no power brakes.. Even the non assisted automatic cars had the spring... again, that is my reasoning!

I believe there's some merit in Vincent's statements. I'd removed the clutch/brake pedal assembly out of a 66 Impala, and sold it on ebay a couple years ago, but don't have any photo's , nor remember if it was a power brake car.

The pedal setup seen above was from a power disc brake / manual steering 70 Impala, but that car had been messed with long prior to me getting a hold of it, so no telling what the original setup was, or what had been added.

I can tell you one thing, getting the spring, and the clutch pedal all installed while laying in the footwell was a challenge. Doing it on the bench, then installing the assembly prior to dash installation is likely a piece of cake.

Vincent, I don't think that's a factor in the 1969 case. By that time they show it the same for power and non power (and power is shown separately under the J50 option sheet).

At least they don't show any different between power and non power that I can see. I'll look again to be sure.

 I understand what you are saying but I have a couple '70's here as well with and without power brakes, I will check. This is also from the book and as you can see, all is for standard brakes and there is no part number in front of the last entry, the power brakes...  I don't ever remember seeing them on a power brake car but there is always an exception.

My 1969 Parts book lists 3921686 as the spring for:

1967-70/ALL-EXC PB
1967-70/ALL PB WITH CRUISE

So manual brake cars or cars with cruise control, I guess. The first part makes sense as the booster adds a return force, but I wonder why cruise? To prevent a misadjusted brake pedal from cancelling cruise I guess? Seems weird to me that it needs both!

Ok.... that's clearer and makes sense... I have a '67 and '68 Grande here with cruise... if I can get into them, snow, I will snap a few pics.... (never pulled the pedal out of 1 with cruise)
