    i am wondering if it is economical to use a 14bff from a late model ifs pickup on a k5. they come equipped with disc brakes, with parking brake, so whats the drawback? no one ever mentions this setup.

    Who knows, but those aren't 14ff's those are the AAM 11.5" axle with rear disc with drum E-brake.

    yeah if they were easy to come by im sure more people would use them, i think they have the 10.5 and 11.5 axles in the newer trucks, but the 10.5 would be way more common

    no lots were 14ff. i have seen more than a few in my day.

    and thay look like this. http://coloradok5.com/forums/showthread.php?t=184036&highlight=14+bolt

    and if you can find one used GRAB IT UP NOW.

    also keep a eye out for newer box vans. like budget and penske rentals. thay have a dana axle in them with all the same stuff. and that would be better for those who want real low gears.

    Also arent the IFS rear axles wider than the SFA rear axles? I heard somewhere that the IFS front was wider and subsequently they widend the rear. If I am wrong let me know I dont have one to measure.

    the draw back is the perches on some, and the gear ratio


    I can get a few of these for a good price.. but having to re-gear kills it

    14 bolt...with 4.10 100 to 200 bucks..bolts in

    add 250.00 or less and you got disk on it!

    mine is not, but I helped pull a dana 70 out of a junk yard here..had very very low gears,

    ice cream trucks and panel truks are in alot of junk yards here..half off day makes it that much better of a deal

    yeah, the reason this topic interested me was because i need to get ahold of a 14bff and when i get it, i want to do the rear disc conversion. its seems to me that when you do a disc conv. on the older 14bff, there isn't very many solutions for the parking brake issue. so i was just pondering the idea of a late model version.

    The IFS 10 1/2" 14bolts are wider than the older ones.I have a 01 2500HD with that rear and the WMS to WMS is 68"

    I am not overly impressed with the rear disc brakes on these trucks,for some reason they like to chew up rotors.I have replaced them twice so far and the truck only has 80,000 on it,many others have had the same problems even the 1/2ton folks.
    I think I heard GM was going back to drum brakes!

    I heard that they were going to do disks as an option, years ago. They haven't yet. Grease your slides, every time you rotate. Grease grease grease. With the pad's thickness they will last forever. No caliper will last long if it only applies pressure from one side.

    grease all you want. it might work.

    the real problem is under the pad shim. the rust starts there and swells up . then it pushes the pads to tight on the bracket. then only 1 side works. after a few months of that your rotor is solid rust on the non working face. then when you discover you have problems you need to buy pads /rotors. then you need to remove all the rust from the bracket. also check the slides thay freeze up bad also.

    also check the new pads for fitment problems on the brackets. i have to rework lots of them to fit with out binding out of the box new.
