So I swapped out my stock axles with Dynatrac 60’s, which also included going to a larger brake set-up (14.25”) - now my brake pedal travels almost to the floor.
Don’t misunderstand me, the truck stops - but I waaay prefer the ‘stock’ feel as opposed to the nail biting, heart stopping trip to the floor my foot does now.
Anyone else have an issue like this when going to larger brake? Is a larger MC the answer - thoughts ? ....
Try bleeding the brakes(I imagine you bled them once). To truly bleed the brakes you may have to take it to the dealer unless you have access to a "dealer tool" which is software to activate the abs so that you can assure the air is out of there too.
You definitely have air in your brake system, and definitely need to bleed your brakes.
It's really easy, just make sure you have a friend to help you pump the brakes. Start at the rear passenger side, and move towards the master cylinder. Good luck, and have fun wheeling those 60's.
Somethings it takes a while to get the air out. Yes abs bleed requires a scan tool. I have alwasys been able to got the air out the standard bleeding way but the last time I had the brakes of I could not and would get a random pedal to the floor. I had to do the abs bleed 3 times.
If you pump the pedal a few times does it give a more solid pedal feel? If so, then you most likely have air in the system. If not, you may very well need a M/C with a larger bore or longer piston travel.

‘Been a busy beaver since my initial post - DEFINITELY no air in my lines, and the ‘ABS bleed’ didn’t change the situation either (although thank-you for the ‘heads up’ on that procedure - I learned something there ...).
I ended up spending an hour (and the better part of a bottle of Gibson’s) on the internet to find out the best out of two options I had for a larger MC.
So that’s my next Saturday planned out - I will let everyone know the results next week ....
I will add that I installed dynatrac 60s front and rear in my LJ and experienced a softer pedal feel like you describe. But it still stopped well running 39” Krawler stickies. I didn’t like the pedal feel but it worked so I left it alone. It got better as the pads bedded in too. How do the brakes perform?
