Scottie-GNZ Posted May 10, 2001 Share Posted May 10, 2001 I thought by now there would have been a way to make those brackets available, but I guess not. Jeromio's effort must be applauded but that is not the proper to go about doing it. If there is enough interest, I can talk to my machinist about doing a CAD and stamping them out on his CNC machine. I will come right up front and say that I will help to get it going but I want no part of another group purchase . Someone else can lead that charge or better yet, some enterprising business person front the production cost and resell to members at a reasonable price. The machinist does quality work and is a personal friend. If he is involved, I will not subject him to personal contact with everyone involved. One person organizes it and works with the machinist and the machinist makes some bulk number and gets paid once. Let me know if I can help.

Guest scca Posted May 10, 2001 Share Posted May 10, 2001 i had a maxima bracket new loaned to me by Rueben, i looked at making them but the costs seem fairly high- a run of 50 pcs was what i was thinking originally.. it needs to be a big run to make it cheap..

Scottie-GNZ Posted May 11, 2001 Author Share Posted May 11, 2001 Mike, if you are still interested, I can get you an estimate. It seems the accuracy of those diagrams are in question and I apologize to whoever drew them if that statement is incorrect. I believe a couple of pics with different angles is all I would need to get an estimate. Quote Link to comment Share on other sites More sharing options...
jeromio Posted May 11, 2001 Share Posted May 11, 2001 Just to prevent any possible confusion, I didn't create that brake bracket drawing - I'm not exactly sure who did. All I did was resize it (thru trial and error) so that it would print actual size. The brackets work well with the 82 280ZX turbo rear calipers that I got. Those calipers aren't cheap though - plan on spending $100 or so and be happy if you find them for less. Rebuild kits are high too. Anyway, I agree that this is an excellent area for a group deal - it's just too bad it's too late for me. But mine are on and they work.

All I did was resize it (thru trial and error) so that it would print actual size. Jeromio, are you saying the labelled dimensions on it are incorrect? Or you just wanted actual size to help you in building your own? Of the two designs as I understand it one allows the later 82/3 ZX calipers to be used and requires a larger bracket that goes around the rear hub on it's backside. I'm assuming it's this drawing http://www.hybridz.org/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=6&t=000585 with late calipers as Ron dictates early with his drawing having a different bolt pattern/spacing. The 2nd design as per http://hometown.aol.com/rolerdynamics/private/brakes.html uses the earlier calipers and is a cheaper design to have made (or so I think/who knows)? Is one easier to install than the other? Could this be easier done from flat plate and an arc cut out of the base to clear the hub (Ron has a central welded 'crosspiece') or is their something else to clear? In other words, if someone is to make these (I just sent them off to a CNC shop for a quote in a day or two) which is preferred? I know later calipers have larger pads by ~25% AIR but my early ones seem quite adequate if that's the easier option. Is the ebrake cable adaptation a no brainer or?? Or is their a 3rd design for which a new/unique bracket would be preferred (200SX calipers etc..something newer/more available good shape in yards as we know new ones are pricy)? thanks As well I'm assuming the maxima brackets are next to impossible to get if you dont' already have them Mike?

Danno74Z Posted May 11, 2001 Share Posted May 11, 2001 Scottie-GNZ, I "drafted" up that Maxima bracket drawing about 3 months ago to help people out who were thinking about fabricating their own. Apparently, the real-deals are no longer available through Nissan so as a favor to the members I made the drawing by using an original one that I own as a template. I used a vernier caliper for most measurements so the "accuracy of those diagrams" should be very close in order to make a copy. Both Pete and Mike were gracious enough to post the drawing on their respective web pages. It now seems or at least I feel the drawing is causing more confusion then goodness so I going to ask both Mike and Pete to have it removed from both sites. This will end the confusion and someone else if so inspired can draft a more accurate one up. Again, this drawing was just meant to be a guide at best and not a detailed mechanical drawing. jeromio's brackets seem to have come out very well after some hard work on his part (shaping and detailing) but I don't think the drawing is too inaccurate to be worthless...But if the folks here think it is I will have it removed.

Modern Motorsports Ltd Posted May 12, 2001 Share Posted May 12, 2001 Danno, no one has said your drawing is wrong at all. I asked Jeromio and he hasn't replied yet. I have a hunch he just resized it to print actual size to use as his own template as he was welding/cutting his own stuff. I could see some errors coming in with the number of steps their. It's mainly nailing down that spacing from the outer bolt pair to the lower main pair to make it a bolt on piece skipping the hub removal part that's needed as I mentioned. That's how I understand it anyhow. Quote Link to comment Share on other sites More sharing options...
spotfitz Posted May 12, 2001 Share Posted May 12, 2001 I have to put my $2 in here. Since I have already made brackets for the '82-'83 ZX caliper/rotor combo using the flat Maxima brackets off an '88, I can say that I used alot of the information off the drawings Danno made, for comparison purposes only. For the process of using the flat bracket to make the offset bracket I had to take every and all measurements I could get to make this modification work. When gathering information from the flat bracket and from measurements of my own equipment and comparing them to this public drawing I found all the offset, bore and center line measurements to be correct within reason.(don't jump me yet)Considering the bracket is a stamped item with "flashing" I would consider the drawings to be good enough for the brackets to work. And heres why. Even after many hours of measuring and test fitting and measuring some more and then numerous hours in AutoCad drawing them and finding more measurements were needed, I still had to do some modifying on my "CNC machined" brackets to make them work, this even after getting them back to the house only to find that the center bore was opened up on an off center state, do to the original center being off center by the manufacturer(did you get all that?). And even after acouple more hours with the machinist to fix this problem I still had to modify them to work. Depending on the method and/or material used to make these brackets they can be "adjusted" afterwords as I had to do. As a side note, if anyone wants my drawings for nothing more then to COMPARE with or take ideas from or anything else I am willing to share them. I do have to make a disclaimer. Although mine work for my application, I am in no way responsable for you &^%&^% them up! Quote Link to comment Share on other sites More sharing options...

jeromio Posted May 12, 2001 Share Posted May 12, 2001 So it was Danno who supplied the drawing! For which I am highly grateful. I think I knew that and mentioned it in a (much) earlier posting on th is same subject. Some internet entrepreneur should set up an "email a 6 pack" service. Anyway, yes, the resizing to which I referred was merely to make my printer produce a "lifesize" version of the part that I then cut out and used to mark on the steel plate. That drawing was plenty accurate for me. If the brackets are to be mass produced - I would recommend aluminum. I know of at least one shop in tiny little Durham here that has a CNC plasma torch that could whip out 3 dozen of the pieces for very few dollars. As MikeSCCA implies, you pay for the setup, so costs go down rapidly the more units you have made. Personally, I lack the intestines to sit on >$1K of Zcar parts. I can just see my wife's face as she screams "You paid how much money to have all these parts made??!" Sidenote: I had similar experiences as spotfitz - the tolerances on those Datsun rear hub carriers is not all that tight (at least the outside dimensions). I ended up with brackets that should have been swappable drivers to passengers side, but were not. And one tweak I would add to Danno's drawing would be to add more metal to the bracket end of the "ring" that bolts to the carrier. That way the bracket "ears" could be moved farther out, preventing clearance problems with the outside of the cast carrier. Also, the inner hole would need to either be larger by 2mm or more to allow for variation, or else the part would need to be sold as a "trim to fit". And I had made one alteration which was to cut out the ears as one piece, with a strip of metal joining them together. This turned out not to be such a good idea. I thought it would make it easier when welding the ears to the ring, but it created much grinding work - definately not worth it. Quote Link to comment Share on other sites More sharing options...

When they fabbed my brackets from the flat ones, they simply cut the ears off from where I told them to and at what angle and made a jig to put everything in position and "fill"weld from the one plate to the ears. The welder did a good job and it didn't need much grinding to make pretty. I was going to have them powder coated. You Really see them things going down the road.

Danno74Z Posted May 12, 2001 Share Posted May 12, 2001 All, I perhaps got a little too defensive and I apologize for that. Thanks for the kind words and the drawings will stay put for however long Pete and Mike want to host them. Danno74Z Quote Link to comment Share on other sites More sharing options...
Guest scca Posted May 13, 2001 Share Posted May 13, 2001 briefly.. i will have a 11" rear rotor setup that can go either 4 lug or 5 lug.. this will use a NON factory race type rotor with a aluminum hat to match the front brake upgrades #2 and #3. it will use the outlaw 2800 caliper with 4 pistons and also have the capability of a BOLT on e brake with mechanical spot calipers.. this is currently in process for 2 people and Jim may make #3....

BLKMGK Posted May 13, 2001 Share Posted May 13, 2001 Okay, let's talk about alternate ideas... Mike/SCCA is working on a setup for me right now using Outlaw rear calipers. Guys, these things cost right about where the ZX stuff does, is aluminum, and looks damned nice! The Wilwood calipers might also work if that's your preference. Yes, there's no E-brake but he's waiting on a set of Wilwood Spotz now that should be adaptable. In my case I'm 5lug but he should be able to accomodate 4lug if there's demand enough. I'm not sure hwo easily the E-brake cables will bolt up but I note that Lokar is making a cut to fit cable now too. Yeah, this all adds up but... Presently I'm looking at 10inch rotors. However Mike thinks that 11inch will work better (anyone want a set of 10inch 5lug with 0 miles?) and I've asked him if there's a vented OEM rotor to consider too (hey, why not?). I'm not sure what the brackets will cost, heck I don't even think Mike knows yet, but I think when you add up the costs and the hassle of getting good SX or ZX rear brakes that this is an option worth considering. Hell, at this point I'm paying for the R&D so at least consider it BTW - should have my fronts all done here soon. I've made some silly mistakes like swapping the struts side for side and control arms too but it's getting there! Should have it done this weekend and some pics up as well when I've got time. This sucker is going to have NO problems stopping! Quote Link to comment Share on other sites More sharing options...
