Lengthening brake rod on CJ7 brakes

I just put in a CJ7 power brake setup, stock bell housing bracket, dual booster, and corvette MC. It all fits nice but the pedal is a little over an inch and a quarter low, and doesn't contact the brake light switch. The brakes work well but the travel is limited. I know people are going to tell me I should ditch the CJ7 bracket, or go with YJ stuff but I got the entire setup for $20 bucks from a wrecked Jeep. I see Tri County sells an adjustable rod for $40 but that seems high given what appears to be simple. But my question is whether it would be ok to simply take out the stock brake rod, cut it and add the missing length (remember on stock CJ power brakes the rod is removable from the mounting bracket). This would seem to move the pedal back to the normal height (as when manual) but are there down sides to doing this? Is it safe if someone qualified welds it?

Thanks for your input

Re: Lengthening brake rod on CJ7 brakes

Your main question is, "Is it safe if it's welded properly?"

Maybe. The brake rod works in compression, so it must be stiff. If there are any doubts, try to find a piece of DOM tube that's a snug fit over the rod, and nearly as long as the new length.That way there will be do chance of it buckling at the weld in a panic stop.

Or, don't ever stop in a panic. [img]/ubbthreads/images/graemlins/grin.gif[/img]

$40 doesn't seem that expensive for something as important as your brakes... especially after getting as good a deal on your brake set-up as you've done.

Re: Lengthening brake rod on CJ7 brakes

That's what I did to compinsate for a thicker firewall on my fiberglass tub:


I didn't want to just butt weld it so I used a piece of tube. I even have a length inside butted up to each section just so there are no gaps.


I left a section at the normal dia so the boot will fit on the rod.

Re: Lengthening brake rod on CJ7 brakes

Thanks for this information.

I am in the middle of replacing the body and this helps.

I have some questions...

Did you have to lengthen the clutch rod also?

What manufacture (of body) did you get?

How did you get it off of the truck?

Thanks.

Re: Lengthening brake rod on CJ7 brakes

The clutch rod is next on my todo list, but it works OK now.

I have a 4WD tub.

I also have a nice chain fall so you back the truck in lift the tub drive the truck out and push the frame unde it. Probably not much help if you don't have a barn with an 11' door opening to get the truck in. Actually 4 guys could probably lift it.

Mine went off and on with me and just one helper. Once everything is stripped out it's doesn't weigh much - couple hundred pounds, maybe a bit more. But if it still has seats, roll bar, instrument panel, steering column . . . get more help.
