the brake pedal height is awkwardly high compared to the gas pedal. it's off by about 3 inches so I need to pick up my foot to move to the brake which makes for poor reaction time for braking and the steering column rubs my knee. Car is a 1969, any ideas for a fix?

Assuming you have manual drum brakes at all 4 corners?

If so, the only solution is a power disc conversion. There are 2 holes for the brake pushrod to attach to at the brake pedal lever.

The top hole is for manual brakes, the bottom hole is for power brakes (less leverage needed to actuated the system)

Otherwise, what you describe is normal.

Are you saying the brake pedal is 6" higher than the accelerator, ie. the normal 3" plus another 3", or a of total 3"? My '68 brake is about 3" to 3 1/2" higher than the gas now and always has been.

Could a seat extender get you more legroom? I know I enjoy the extra room I got with one.

They are disc all around, my neighbor who has a 65 GTO noticed it was awfully high compared to the gas and he has stock brakes. I'll check for the holes in the push rod. The brakes are really tight so not even close to stomping to the floor. Will take a few photo snaps when I get a chance to illustrate.

Are they power discs?

just measured and it's closer to 4-5 inches higher than the gas. Seat extenders, tell me more....
Someone previously told me the gen1 firebirds were small, I have the slid all the away back to accommodate the brake, but I could probably move forward one notch for the gas. So if I can the brake 2-3 inches above the gas it would be ideal and allow someone to sit behind me. btw: I'm about 5'9"

yes, Wilwoods

They you need to move the push-rod down to the second hole on the brake pedal lever.

looks like it's already on the lower hole closest to the pedal, should it be the higher hole?
Tried to post a pic but failed, does this function work on this site?

In the "Reply" screen, scroll down and you can use "Attachment Manager" to upload a photo.

I’m running Wilwoods on all four corners, a Tuffstuff dual 9” booster, Masterpower Brake mounting brackets and a Corvette master on my ‘68. If the brake pedal is correct the booster rod might be adjusted too long. PM me w/email and I’ll forward a pic.

If it's already in the lower hole, then there is some limited adjustment of the push-rod, but other than that, don't know much about the aftermarket 4 wheel disc set-up you're using.
