    Have you noticed a difference in the disc brakes? Everyone I talk to loves them. Thinking I'll get them on my next trailer.....was gonna try and find a cutoff for my truck with them too.

    Yeah I can notice a difference, I can’t say it’s huge but it’s definitely there. I think a tractor trailer all disks would be real noticeable.

    Been a bit skerrrrrrrd to.

    Bobtail, leaving the shop, I stood on it and boost hit 40+, and I think I lost traction on dry pavement.

    Max heat, if pyro correct, is 900. Seems to like 1500-1600 RPM for a driving range now , for lower pyro.

    Y'all probably know this but, it's not more pressure, it's more "swept area". Kinda like having two door jams under the door instead of one. It has a larger footprint and more traction against the drum/ and or disk, depending on the braking system. The springs still exert the same amount of pressure.

    Does a 30” and 36” chamber have the same size spring? I don’t know, I do know the larger the surface area the more pressure it’ll exert. Those air bags we were talking about that will lift a semi trailer don’t use a tremendous amount of psi the just has a lot is surface area. I was looking at those airbags after that. The ones I found were all rated at a max working pressure of 120psi, the only differences were the dimensions. My assumption is the 36 square inch chamber has a stronger spring for parking therefore a bigger surface area diaphragm to compress the spring.

    The air bags that we used for recovery work were something like 4'x4'x6' when fully inflated. 4 of them would lift a fully loaded reefer @ 7 psi.

    I guess that is the comparison that you were making?

    Gosh, that reminds me I have a whole set of Gearwrench sockets my wife bought me a long time ago. Are pretty neat being able to slip down over long threads or shanks.
