    What year did they change the brake hoses that bolt to the front calipers? I have what I believe is an 85 front 3/4 ton axle and my brake hoses have a wrong type of end. The hoses are also way too short and are streched bad even when the blazer just sits there. Anybody have the NAPA part # for the brake hose for an '85 3/4 front end? Thanks.

    I think somebody gave you the wrong part. If you had a 10 bolt half ton and put a 10 bolt 3/4 ton axle the brake hose should be the same. 10 bolt and Dana 60 use the same fitting the only different one is the Dana 44.

    I have the right part because the calipers that came off the 10 bolt and the new ones are the same. There must have been a change in the end they used in the late 80's!?! The one I have now is round with 2 tabs sticking out on the sides. The one I need has no tabs. I would just grind the tabs off but where the end bolts to the caliper is a lot lower and the brake hose streches way too much.

    Mounting hole for hose should be on top of caliper. Could have calipers reversed, left on right right on left? Only thing I can think of.

    The calipers are right because the bleeding nipple is on top as well.

    Don't have part number, but had to go in and just find a hose that worked. Look at 84 one ton, as it might have longer hose. I just did trial and erro at the parts store for the right length and correct banjo bolt. Had to grind the ears off of end, but worked fine.

    If you ain't hurt, you ain't playin' hard enough.

    As long as the banjo bolt bolts into the calipers ok, then you should be fine with any 80' and up 10bolt brake hose. (obviously, get the length you need). But it doesn't matter how the "shape" of the brake hose end is. I had a couple of 10bolt brake hoses, and the shape of the end were a little different on each, but the banjo bolt threads and size were the same.
