High brake pedal

my 78 cj5's brake pedal sticks out about 4-5 inches further than the gas pedal. In or order for me to press the brake I literally have to lift my leg up, bring my knee towards my chest to allow my foot to clear, and not get my toes caught on the back side of it.

Any suggestions on lowering it to a little more flush with the rest of the pedals?

Thanks!

Nope, that is how vehicles are made. Not only does the height difference make sure you can't easily put both the brake and gas on at the same time, the brake pedal needs the travel to be able to push the pads and shoes far enough to grab in a controlled way.

I've got to go with what Mike wrote. The pedal is directly connected to the master brake cylinder piston rod.

The CJ is a very simple machine that's not designed for speed shifting or braking. (Oh who am I kidding? It's not designed for speed. Period.)It's not a modern speedster where you can just pivot your foot with your heel. What you describe is normal Jeep (or even pickup of the era.)

Change it over to power brakes the pedal is much lower.

Really? Is that on a 5 only? I have power and a friend has manual brakes in our CJ7's and the pedals are enough the same we can't see any difference.
Even so, power brake pedals are the same deal, they are higher than the gas so you can't put both on at the same time by mistake.

I drove it around today and perhaps I am just accustom to my G37 daily driver (obviously sportier than an old jeep) that the distance seems extreme. There is certainly no way for me to press them at the same time with the same foot (not even close), I really don't know if mine has always been like this or at some point in its life something was changed.

Personally, the gap is enough for me to actually fear that I won't be able to get my foot to the brake quickly if I needed - that or get my foot caught on the back of it.

I'll be installing a power brake booster soon - maybe that will lower it some? Either way I'm tempted to cut it, weld a 1-2in steel piece to sink the pedal a pit closer to the floor.

Anyone's thoughts on that?

You can lower the pedal by using a shorter rod that attaches to the pedal. You should add something to block the return of the pedal that the return spring can use as a stop.

It should be the same height as the clutch pedal.

I always find it amusing when (the rare occasions) I let a friend drive mine and almost every time someone says says something about the height of the brake pedal. I don't even notice it anymore. I did shorten my accelerator cable because I wasn't getting my webber carb fully opened (I drove that thing for years without ever opening the second barrel!) so that actually raised my gas pedal up some. Otherwise, my setup looks like the picture John posted. Miscellaneous loose hardware on the floor and all!

X2 on the pedals on my 7. They looks like John's as well. Although, I have to admit, he has help with his (emergency) brake pedal height. Nice bungee!

When I seen the post about power brakes and peddle height, it was my recollection, having installed an original 1979 OEM vacuum booster, there was no difference in the peddle height.

On my power brake CJ7 the brake pedal at rest is a little lower than the clutch pedal. It's always been that way.
