BEEBANI Posted September 28, 2010 Report Share Posted September 28, 2010 So, to avoid more confusion from any newbs, and to put the right info in the right thread, I've decided to post a new thread for these. Parts Needed: Front Rotors: 2002 Honda passport, 2001-2004 Isuzu Rodeo, 2002-2003 Rodeo sport Calipers: 1988-1997 D21 (Hardbody) calipers for 4wd, 2.4L Pads: 1988-1997 D21 (Hardbody) pads for 4wd, 2.4L Lines: Use the rubber hoses for the Hardbody calipers, and make new steel lines for the truck on the pre-1973 trucks only. The 620’s have the right thread on the hardlines and will hook right up. Hardware: 12mm bolts are required to mount the caliper to the brackets, and 10mm bolts are required to mount the bracket to the spindle assy. Master Cylinder 7/8” or 15/16” bore from any year 280zx with vertical mounting tabs. The 620 master cylinder will also work, but the mount has to be modified to fit the firewall on the pre-1973 trucks. Instructions: Remove wheels 1. Remove brake lines at the frame (320,520, and 521 only) 2. Remove drums 3. Remove dust cap and remove hub assembly 4. Un-bolt backing plate and remove 5. Install caliper bracket with ears facing rearward and spaced inboard 6. Install hub assembly onto spindle and re-install dust cap 7. Slide rotor over hub 8. Install calipers with bleeder at the top 9. Install lines 10. Bleed Master cylinder For 620 owners you can just replace the master with the larger bore M/C. To keep fabrication to a minimum use one that has the mounting tabs in the vertical position. I was able to use the 15/16” m/c and booster from a 720 but there was some modification needed to mount the booster itself. All of the fittings on the 620 are metric and you already have the required two lines. 520/521 install requires replacing the SAE fittings with metric ones. 520/521 installs will also require either a 280zx-proportioning valve or something comparable (Willwood adjustable) and lines run for the fronts. I provide the brackets and all 10.9 grade hardware for mounting the brackets and calipers. They are currently painted as the zinc plating didn't work out well. The price is $160 shipped anywhere in the US, and another $20 for our Canadian brothers. All other countries contact me for shipping cost. 5 1 Link to comment

]2eDeYe Posted September 28, 2010 Report Share Posted September 28, 2010 What happened with the zinc coating? It looks good on your test set. Still got that 5-speed? :D Link to comment
Charlie69 Posted September 29, 2010 Report Share Posted September 29, 2010 Just wanted to say Beebani great write up. That should answer all of the questions any one might have on the install, providing they can read. :D Link to comment
Guest Rick-rat Posted September 29, 2010 Report Share Posted September 29, 2010 I have them all the way around on my 620, will need 15 inch wheels for the front to have enough clearance for the calipers. the rear set can use 14 inch, plenty of clearance Link to comment

Z-train Posted September 29, 2010 Report Share Posted September 29, 2010 Any caliper interference issues with Slotted wheels? Link to comment
BEEBANI Posted September 29, 2010 Author Report Share Posted September 29, 2010 Any caliper interference issues with Slotted wheels? RickRat has slotted wheels, but as he stated, you have to go up to a 15" wheel to clear the fronts. Steve, I do still have the tranny, why? Link to comment
]2eDeYe Posted September 29, 2010 Report Share Posted September 29, 2010 Steve, I do still have the tranny, why? PM'd to keep it outta the thread :) Link to comment
Z-train Posted September 29, 2010 Report Share Posted September 29, 2010 Shit,fuck,piss. just put 14's on the truck. Link to comment
Guest Rick-rat Posted September 30, 2010 Report Share Posted September 30, 2010 I was hoping to use my 14" slotted mags on the front, it is so close but could not make it work. Put a set of 15 inch ultras on, getting used to the way it looks now Link to comment

thor Posted September 11, 2011 Report Share Posted September 11, 2011 Great thanks! And I seem to keep being one post behind you :) Link to comment
red truck 1600 Posted September 20, 2011 Report Share Posted September 20, 2011 Did you have to cut any part of the base of the spindle? Ive seen one that you had to cut ,I don't want to do that because of strength. How do I contact you about purchase of the parts? I'm located in two places San Francisco and Roseville Ca. Thanks P.S. this setup looks really good. Link to comment
