Just finished disc brake conversion

JUST COMPLETED AMC 20 BRAKE CONVERSION. (PARTS LIST) 1 PAIR 1996 NISSAN MAXIMA CALIPERS.
(2) 1998 GEO TRACKER 2 DOOR SOLID ROTORS. 1 SET NAPA TS7421 BRAKE PADS. (2) NAPA 380469 BRAKE HOSES. (1) NAPA 95004 E-BRAKE CABLE. (1) NAPA BK95003 E-BRAKE CABLE. (4) CALIPER MOUNTING BOLTS 10MM BY 1.25 PITCH. THE CALIPER MOUNTING BRACKETS CAME FROM BESRK (EDDIE) GROUND POUNDER FAB. THEY ARE GREAT AND WELL WORTH THE MODEST PRICE. THANKS EDDIE. I HAVE SEEN POST OF PADS KICKING OUT AFTER SOME AMOUNT OF WEAR. WHAT I FOUND IS THE CALIPER MOUNTING HOLES NEED TO BE REDRILLED LOWER ABOUT 7/16" TO CENTER THE PAD TO THE ROTOR. IF NOT YOU WILL NOT HAVE FULL STOPPING FORCE OF BRAKES. ALSO THE UNEVEN WEAR COULD CAUSE THE PADS TO TILT AND KICK THEMSELVES OUT WITH TIME. I MADE SEVERAL BRACKETS TO ATTACH E-BRAKE CABLES TO. I INSTALLED A DISC-DISC PROP VALVE AS WELL. MADE MY OWN TOOL TO HOLD THE METER VALVE CENTERED WHILE BLEEDING. HERE ARE SEVERAL PICTURES. THEY WILL BE LARGE. PICTURE QUALITY IN MANY POST ARE NOT THAT GOOD. HOPE THIS HELPS OTHERS WHO WANT TO DO THE SAME UPDATE.

I am stuck in California with all my parts eagerly awaiting my return to finish my upgrade. Can you post a measurement where the new holes need to go in the brackets?

Thank you for sharing the pictures. The installation is nice and clean and you have given me some good ideas about how to run the driver's side line on mine.

I have read that there are differences between the Maxima and 300ZX brackets. Is that the reason you had to re-drill the mounting holes?

Brackets

TITANJEEP, MY UNDERSTANDING EITHER CALIPER CAN BE USED. IT WAS SUGGESTED BY OTHERS TO MOCK UP THEN DRILL. SO TO GIVE A PRECISE MEASUREMENT I WOULD NOT DO. EVERYONES SET UP COULD BE A LITTLE DIFFERENT. I WOULD TRY TO GET AS MUCH PAD AS POSSIBLE CENTERED ON THE DISC HOWEVER. SHIMMING THE BRACKETS AND ROTORS WILL BE DIFFERENT ON EVERYONES AXLE AS NO TWO ARE EXACTLY THE SAME DEPENDING ON HOW MANY FACTORY SHIMS WERE USED TO SHIM AXLES IN AXLE HOUSING.

Nice work. I've been wondering what to do on mine. Could those calipers have been mounted at the 10 o'clock position rather than the 2 o'clock position to maybe re-route the emergency brake cable above the axle?

Yes, at least that is the way I did mine. I don't think it really matters though.

Thanks for the extra pics, looks sharp. I see what you're saying about it being a flip of a coin as far as cable routing.

E-brake cables

BAKERSHOP, YES YOU COULD MOUNT CALIPERS AT THE 10 O'CLOCK POSITION. I HONESTLY DO NOT SEE AN EASY WAY TO RUN CABLES WITH THE MAXIMA CALIPERS. ALSO, I WANTED TO MOUNT SO BLEEDING WOULD BE AS PAINLESS AS POSSIBLE. GOOD LUCK.

Interesting on the bolt holes..

Maybe I should just predrill all the brackets with both sets of holes? One set in the current location and another set 7/16" farther inward?

The thing with this whole AMC/Nissan Disk conversion, is that I've never done it. I simply cut the brackets based off the CAD File that's been floating around for a few years. I did initially double check the axle flange bolt holes on an old AMC20 axle housing I have at the shop... but after that, I have nothing to compare bolt holes, distances, dimensions..etc. Only that original CAD Drawing.

BlueRubiconrich, which D44 do you have? I did a disk conversion for a Scout D44 rear axle. It adapts the smaller Caddy Calipers to the later (thinner) CJ D30 rotors. I've got the system bolted under my own CJ but I've been too busy to get it all bled out and finished up. Maybe soon..
