Fineline Posted February 26, 2007 Author Report Share Posted February 26, 2007 I have been in contact with Mike about the distance from the wheel mounting surface to spindle fac on the 620 and 521. The confusion I believe is comming from thi idea of mixing the different bearings. This is what he said, "521 thinner than what? the 620? If you're talking the 620, the spindles are the same as the 521....same outer bearing...similar inner bearing...32mm ID. What the difference is, is the "ring" spacer at the bottom of the 521 spindle. The hub surface...where the brake drum touches.....is exactly the same distance from the spindle surface where the bracket would mount. Your brackets will work on either a stock 620 with drums or a stock 521 with drums. I'm pretty sure what you are questioning is that difference I was talking about.....the 2mm. What that is is when you take the 620 drum inner bearing and put it on a 521 spindle with the ring removed. The reason to do this is because the 521 inner bearing is nearly impossible to find...while the 620 is readily available.....although it is a bit different. I have pics of it up on the original disc on a kingpin thread. If you look at them, you'll notice that the .....I just looked..it's page 5 http://www.nwde.org/extras/forum/forum_posts.asp?TID=2005&PN=5 about 2/3's down....boss at the base of the 620 spindle is taller because the bearing is different. Anyway.....check out the pics and the caliper measurements.....if that doesn't give you what you want, let me know and I'll get whatever you're missing. But....basically the answer is that the wheel mounting surface is exactly the same distance from the bracket mounting surface on each of the "stock" setups. It's the intermixing that makes a 2mm differnce. If the bracket was made to offset the caliper 2mm less, then 2mm washers could be put between the bracket and the caliper on the stock setup. The drawback being that there's a lot more 620 guys than 521 guys.....so maybe have to different spacers made and weld up different versions of the bracket :" I guess the answer to everyones question is "yes", these brackets will bolt right up to a 521 without any spacer provided.... 1. You want to use the z32 calipers. 2. You are using the stock 521 inner bearings with the 521 spindle. Hope this clears things up. Quote Link to comment
71-521 Posted February 27, 2007 Report Share Posted February 27, 2007 so reading what Mike wrote, these brackets will work for either the 620's or 521's with no other mods... nice to have that cleared up... I was under the impression that it would work only with the 521's... I would guess that would be the same with Beebani's setup with smaller calipers.... Darned...wish I had know that earlier...Beebani raised his price since he first posted it up... Quote Link to comment
Fineline Posted February 27, 2007 Author Report Share Posted February 27, 2007 That is correct. They will work as long as you are using the "matching" set from whatever vehicle you have. i.e. spindle, hub, bearings. If you wanted to convert your 521 to the 620 bearing style you could do it by replacing the spindle assembly and all I guess. That would make the issue of the lip on the spindle moot. Someonw would have to make sure the kingpin assembly was the same. Quote Link to comment

71-521 Posted February 28, 2007 Report Share Posted February 28, 2007 Uhh, no I didn't. Always been $50 a set. hmm, then someone else did it for you...check the first page of your NWDE thread... If that's the case, then I will be needing a set in 2 weeks...payday...that way they can be here for the spindles I'll pickup at GG... Thanks! Quote Link to comment

At least that's what I charged Dwight for his. I guess I forgot that I posted that. Let me know Paul. Quote Link to comment
71-521 Posted February 28, 2007 Report Share Posted February 28, 2007 Will do... and thank you for providing these for the good of the community! Quote Link to comment
smokeybear Posted February 28, 2007 Report Share Posted February 28, 2007 awesome write up, so this is a bolt on and go thing right?? lets say if you were to bag the front on a 521, would there be any clearance issues. im kinda ignorant on what you guys are talking about, so sorry if my questions seem a little dumb ha ha. if i am understanding this correctly, i would love to buy a set with my tax return money. also, what master cylinder would you recommend using??

BEEBANI Posted March 5, 2007 Report Share Posted March 5, 2007 There shouldn't be any clearance issues. And yes, bolt on and go. Quote Link to comment

tangent Posted April 22, 2007 Report Share Posted April 22, 2007 Im starting to run my lines for the disc brake conversion and about to place the portioning valve.. I bought a bunch of 3/16 line with metric fittings, or they are supposed to be, it said imports/japan, but those are probably the newest japanese cars.. anyway.. the SAE stuff on the 521 I will be getting rid of all of it, but the 81 280 Z stuff im saving the fittings that came off and might flare them onto the new lines, they look a bit diffrent than the new stuff, they dont have the part at the end of the fitting with no threads, and it seems to me that there wont be enought threads catching.. as for the izuzu and 300z parts as of yet I am not sure, that gets me to the question these wilwood portioning valves are SAE right, thats the dimension on the sticker on the thing?? and do i need the brass fittings or do i plumb right into it... lastly, what do i use on the thread before assembly... will regular threadlocker due?? OK I found the type of metric lines at pep boys that should be used on the 280zx M/C and splitters, probably the Izuzu stuff as well.. pep boys had two types of metric lines, the one at the top, and the one on the bottom... the one in the middle is the U.S. thread for the Portioning Valve... you should be able to read the labels that state, Metric, or U.S. thread Quote Link to comment
]2eDeYe Posted April 23, 2007 Report Share Posted April 23, 2007 I wouldn't put any type of 'threadlocker' on brake lines. They are hard enough to get off later as it is. Just make sure they are tight ;) Quote Link to comment
slodat Posted April 23, 2007 Report Share Posted April 23, 2007 Brake lines do not need threadlock. Using it would probably come back to haunt you at some point. The threads taper slightly and "lock" themselves. The wilwood stuff uses 1/8NPT fittings. They are available pretty much anywhere. Quote Link to comment

I'm still dealing with some pretty inexperianced parts guys... they might as well work at McDonalds as much help as they offer. Quote Link to comment
slodat Posted April 25, 2007 Report Share Posted April 25, 2007 To me, there is no way to know unless it is labeled as such. You could go buy a brass 1/8NPT fitting at a hardware store and see how this mates up. Quote Link to comment
BEEBANI Posted April 26, 2007 Report Share Posted April 26, 2007 My guess is yes, because the label says "U.S. thread" get a fitting and check it. Quote Link to comment
ADrummond Posted June 10, 2007 Report Share Posted June 10, 2007 Tangent, that's not an NPT thread on your line - it isn't tapered. I'm pretty sure American brake line fittings are 3/8-24, and metric are 10mmx1.0 (it's hard to tell them apart by eye - they're very close). They don't have to be tapered because the flare does the sealing, not the thread. I suspect the Wilwood valve has NPT threads so you can install the correct fitting (NPT/flare adapter) for the brake lines you want to use (inch or metric) Andrew Quote Link to comment
1hr40minlate Posted October 25, 2007 Report Share Posted October 25, 2007 Hello Fineline, Will these brackets work for the 520 truck? Does anyone know if the 66 and earlier roadster front brakes will work on the 520's? Thank you! Quote Link to comment
Fineline Posted October 25, 2007 Author Report Share Posted October 25, 2007 Yes I believe they will work on a 520 Quote Link to comment
ppeters914 Posted October 25, 2007 Report Share Posted October 25, 2007 Does anyone know if the 66 and earlier roadster front brakes will work on the 520's?Thank you! Dunno, but you might want to price roadster brake parts before you consider that: Rotors: $200+ a pair Cylinders: $280+ for all four. Cross-over tubes: $15 or $25 depending on which one (there's two of each). Quote Link to comment
1hr40minlate Posted October 25, 2007 Report Share Posted October 25, 2007 Hey Fineline - pm me the info and I will get a set for the front. I forgot how much the roadster stuff was! 1hr40 Quote Link to comment
Voleurz Posted November 26, 2007 Report Share Posted November 26, 2007 excuse my ignoarance... but you are making mounting plates for calipers so you can run disc brakes on a drum brake equipped 620 or 521 right? they bolt on with the right caliper and rotor? what master cylinder do you use?
