  • AMC 20 disk brakes

    Finally got around to starting my rear disk set up. Here's how it went down

    1984 Nissan 300zx rear calipers w/ built in parking brake ($15/pair at pick 'n pull)

    New pads ($13)

    1996 Geo Tracker 2 door front rotors ($40/pair)

    2 pieces of 6"x6"x3/8" steel plate for bracket fab. (free-b)

    Total so far: $68



    Cut off old backing plate, you need to leave a piece to act as a shim for the bearing.

    I got a CAD drawing from a guy on Pirate 4x4, and fabbed a bracket of of 3/8" steel from it.

    grind down one of the inside edges to fit the profile of the back of he flange so it fits flush

    bolt everything together and you're done! I had to shim the caliper off of the bracket a little to make it fit right. The stock Nissan hoses screw right onto the stock hard lines too! I still have to work on the e-brake cable, I may have to find a place to swedge a new fitting on my cables.

    I didnt have a whole lot of time this weekend, so I just did the disks to start. Took it for a spin, and there is a definite improvement even with stock prop. valve and MC, but it still needs some more umpf. I have a ZJ 4 wheel disk proportioning valve that Im gona add, and i need to find a new MC too. I bought a ZJ MC and booster from the J/Y, but the booster wont fit, my clutch MC is in the way, so on to plan B. Ill research that some more this week, maybe a YJ booster and bracket (to clear the clutch MC). I think Ive got one laying around somewhere.

                Do those caliper brackets just bolt up using the existing holes on the axle flange? or are they welded. If there is no welding on this set up, I am definetly going to need those drawings for the brackets cause I am doing this upgrade. Nice work man

                              Did you have to turn down the center hole of the disks to fit over the flange on the end of the 1 piece axle shafts?
