    1/2 to 3/4 brakes ???\'s

    Does anyone know if the calipers are interchangable. I have A d44 w/10 bolt 6 lug rotors and calipers and am trying to get more "grab" from the front brakes. Would like bigger calipers and pads and possibly a 3/4 ton master cylinder. Any ideas out there??? Thanks in advance.

    Calipers and disc pads for 1/2 ton and 3/4 ton are identical.
    I wnet as far as having the disc pads for 1/2 ton and 3/4 ton pulled at the parts place for comparison...they were identical except for the price. The 3/4 ton stuff was more expensive [​IMG]

    I have the 'alleged' D44HD in my Jimmy...I could not find a caliper that was different. In fact my old 1/2 ton 10 bolt calipers fit up to the D44 HD and were exactly the same part.

    I would really like some confirmation as to wether or not a HD is any different than a converted 6 lug 44. I've heard that the HD came with thicker axle tubes and I've also heard it never existed...

    I do know the D44 under my truck was out of a 3/4 ton originally...and was told it was a HD.

    I know that some of the early 70's D44s such as the one in my truck had a thicker walled but smaller diameter tube, but that was both the 1/2 and 3/4 ton, so i think they just called it a D44HD to identify it as a 3/4 ton, with the 8 lugs, nothing more.

    Will I get more pressure from a larger master cylinder? If so what should it be off of?

    from the info I have been given. the difference in a 3/4 ton master is that it will push more fluid. The 3/4 ton rear wheel cylinders are much bigger and NEED more fluid to operate properly. the front calipers are the same though. the difference in years is the bolt that holds the banjo fitting in. the caliper pistons are the same size.

    your right. I don't understand the jeep thing!

    Since my calipers in the rear are bigger than the wheel cylinders this will likely help out as far as pressure to the rear correct?? What year should I look for to bolt up to a 86?
