Brake pedal height

[74 Bronco Billy]

WHat is your brake pedal height? Is it 8" or 6" or 5"? Are you hydroboost? I am calibrating the brake pedal height and need to know what "normal" should be. I think in a panic braking situation, having the brake pedal not at 8" but 6" allows one to move his foot off the gas and on to the brake just a bit quicker.
Give me your measurements ;D and your thoughts.

Thanks,
Forrest

I prefer to have the brake pedal at least an inch below(closer to firewall) the clutch height for two reasons. 1) it lets me toe/heel the brake/gas for hill starts. 2) I'm running vac boost front discs so that still gives me plenty of pedal travel to stop. Not sure this helps, but it's how I set us.

I set mine at clutch pedal height and no idea what that is, for no reason other than I cant recall seeing them set at different heights.

I just went through this when installing a new vacuum power break setup and ended up at 6.5 inches. At this height the master cylinder completely bottomed out and it left a small amount of space between the back of the pedal arm and the floor pan. I have a feeling that the booster style and master cylinder combination you use will have an effect on the perfect height for each combination.

Yes, they are usually equal height, but the clutch pedal is adjustable while the brake pedal is normally not. At least not from the factory and at least not for the manual brakes.
Bronco Billy is obviously setting his up custom, but when you install a standard replacement part, if you need to adjust the clutch pedal to match there is an eccentric up at the top, near the pivot.
It's actually the bumpstop, but it's on an eccentric bolt so can be tweaked a bit within a range.

Although you can use the brake pedal as your reference, there is actually a clutch pedal height adjustment procedure in the book that gets you usually where you need to be.

Guess I forgot to say that I have a C4, so no clutch pedal to use as a guide. I'd really like to know what people have for a height for their brake pedal if they are an automatic and have hydro boost. And what the difference is between gas and brake pedal height.
Thx

If nobody answers soon, I'll go out and take a measurement on mine. It's not original however, so nothing is etched in stone.
New floors, new pedal (no auto in '68), and maybe even a new gas pedal with the Explorer conversion. But even if that last is original it can be at a different height due to the new setup.
But the brake-to-floor dimension should at least be close. It feels pretty natural to me, so can't be too far off from an original '74.

I have 4.75" from the top of the pedal pad to the floorboard with a wide pad pedal, automatic, and hydroboost. I have an adjustable pushrod on my booster so I apparently dialed in this height at some point over the years. I know it's lower than stock but I like it.
