Guest scca Posted January 6, 2001 Share Posted January 6, 2001 thought i'd move this to a different line to find it easier i was pretty sure the maxima bracket wouldnt work as the solid rotor is closer to 10" and couldnt see how the same bracket would work for a rotor over 11". i reiterated this in a earlier thread somewhere on this list.... questions now.. 1) are newer maximas vented rear disks that would be a possible parts donor? 2) i need some clarification: the maxima we all talk about is a solid rotor (REAR) so how can turning down a vented 300 rotor fit into a solid rotor caliper? 3) the 300 rotor being turned smaller for a maxima is that for FRONTS? 4) ive tried virtually every nissan rear setup "easily" available and none are a better setup than the current 82+ caliper offset with the maxima bracket. the 87-88 300 rears AFAIK need a larger bracket than the maxima one. ok enough rambling......... ------------------ Mike mike@fonebooth.com http://www.fonebooth.com/brakes.html raceparts and brake upgrades.

Guest Anonymous Posted January 6, 2001 Share Posted January 6, 2001 We're talking about z32 rear calipers and rotors, no maxima parts 'cept for the brackets. The maxima brackets have the same bolt spacing as the rear z32 calipers and rear 87-89 turbo z31 calipers. 1. No maxima parts 'cept for rotors 2. No maxima parts. 3. Yes, I just mentioned that maximas can use front z32 calipers in the front with turned down rotors because he asked if it was possible to turn down rotors. 4. The 87-89 rear turbo calipers fit right onto the maxima brackets. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 6, 2001 Share Posted January 6, 2001 ahh, see your #3 i thought you were still talking rear brakes that was the problem! and most nissan calipers have the same bolt spacing (rears anyway) so they will all "bolt" tothe maxima bracket, but the diam. of the rotors changes constantly and this affects the bracket. and i found a 81 maxima at the local wrecker yesterday. FIRST time ever.. they are going to pull the brackets off for me! i dont know the price yet but i dont care.. just something to play with... ------------------ Mike mike@fonebooth.com http://www.fonebooth.com/brakes.html raceparts and brake upgrades.

Danno74Z Posted January 7, 2001 Share Posted January 7, 2001 SCCA, "i was pretty sure the Maxima bracket wouldn’t work as the solid rotor is closer to 10" and couldn’t see how the same bracket would work for a rotor over 11"." If you were so sure it would not work how come you never mentioned it. It is very easy to be a critic but if you have information why don't you offer it to the group instead of being so secretive. I'm sorry I just don't understand that attitude. I think the Z32 rear brake system will work on the older Z perhaps now with some refinements. Number 4 above you tried virtually every rear setup - OK, have you tried the Z32? If you have, what will and what won’t work other then the Maxima bracket. Please share your knowledge isn’t this the reason for HybridZ and being a member. Danno74Z Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 7, 2001 Share Posted January 7, 2001 Hey danno, while you're at it... The rear z32 calipers use the same brake hoses as the s30 drums do, right? They have a short tube on the caliper, then the hose correct? Just wondering.... Keep up the good work ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 7, 2001 Share Posted January 7, 2001 well i HAVE Z32 brakes on my car currently been on it over 2 years now..i made weld on brackets like i do for the 5 lug conversion but they were longer for the Z32 calipers. i actually just cut up a pair of 86 rear a-arms for the brackets and then welded those ears onto my 240 strut. if you locate the old thread i replied to Morgan (i think) that i didnt think the larger rotor could possibly fit. this was over a month ago.. it was Morgans idea originally that he thought the Z32 caliper (or was is the 87 turbo one?) would be a bolt on with the maxima bracket. i explained then that due to the larger rotor diam i didnt think it was a go. when someone else posted they thought it was a go i thought maybe i was wrong and was waiting to see. it wasnt being secretive everyone wants to try for themselves what they can make on their own. AFAIK the only "bolt on" with no mods is the current conversion we all know about. all the upgrades beyond that are custom made and not a OEM type parts swap . ------------------ Mike mike@fonebooth.com http://www.fonebooth.com/brakes.html raceparts and brake upgrades.

BLKMGK Posted January 8, 2001 Share Posted January 8, 2001 Guys - I DO remember Mike mentioning the rotor diamter months ago on this. Turning down the rotor sounds like a possibility, I'll be interested to see how this works out! Heh, I still vote for a repro Maxima bracket though but that's a purely selfish thought (lol) Quote Link to comment Share on other sites More sharing options...
alsil Posted January 8, 2001 Share Posted January 8, 2001 OK- let me see, the Maxima caliper bracket will bolt the Z32 rear caliper in the right position to accomodate the z32 rotor/parking brake assy, all you have to do is enlarge the mounting holes to bolt the backing plate to the hub? That sounds too easy. Got the pics, looks good, what about the price for all of these parts? that would really be the determining factor.

Guest scca Posted January 9, 2001 Share Posted January 9, 2001 i dont think theres enough room to elongate the holes and use the maxima bracket. actually i'll go out on a limb and state that there isnt enough meat on the bracket to do this better to make custom brackets so that rotor changing in the future is a off the shelf oem part ------------------ Mike mike@fonebooth.com http://www.fonebooth.com/brakes.html raceparts and brake upgrades.

Guest Anonymous Posted January 9, 2001 Share Posted January 9, 2001 What I'm after though, is: Can the z32 rear caliper be used with a flat bracket(ie. one that anyone could easily make) or can it be used with a flat maxima bracket without spacing it in/out? Can the parking brake be made to work easily? Anything can be made to fit in the rear, but the easier the better in my book. Plus these aren't floating calipers, which is good. ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted January 9, 2001 Share Posted January 9, 2001 Morgan/Al Sorry to report that the "hat" parking brake mechanism will not work on our older Z cars - a real bummer for sure. The problem being that one does not have enough offset from the mounting bracket to the face of the stub axle flange. The offset is 2.125 and to make this work one needs about 2.5" and this is without the Maxima bracket installed. If the bracket is installed you really need about 3" because its .5" thick. The Maxima bracket fits fine on the hub and bolts up perfectly, I even had the caliper mounted to the bracket to take my measurements. So the "hat" parking brake system as it stands right now will not work with our Z's No way no how. So we are not quite back to square one. I am going to use the caliper, bracket and a rotor that has the right diameter and offset. I will then have to rig up a spot mechanical caliper for a parking brake. A good learning experience even though the end result wasn't what I hoping for.

Guest scca Posted January 9, 2001 Share Posted January 9, 2001 with the 300 Z32 caliper/rotor my "flat" brackets are 3/4" behind the stub axle flange . so i dont see how its possible at ALL to make it a "bolt on " with maxima brackets. personally i wouldnt want to turn rotors down 1/2" every time i need to replace one. granted that wont be often with a "toycar" but i guess my point is turning the rotors will cost as much or more than having mounts either welded on or custom made to bolt to the axle flange.

Danno74Z Posted January 9, 2001 Share Posted January 9, 2001 Morgan, Cutting down the small drum shoes would not work. The little drum shoes are approximately 1" wide now and bonded to a steel plate like its big brother. If you remove ½" of material your left with a very marginal pad. Besides its not the pads that stick out so much but the entire backing plate that everything is attached to. The backing plate has a slight bulge to it because of the room that is needed to offset the little drums and adjustment screws. The Maxima bracket will work if you can find them new or used. As someone else mentioned years ago you can weld a bracket on. I have the bolt on brackets so I'm using them. There are numerous hot rod supply companies that sell every imaginable rotor in any size, offset and shape (vented, slotted, etc.) Danno74z Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 10, 2001 Share Posted January 10, 2001 well after you custom order your rotors with hats attached i'd be curious as to the cost. i havent looked into much street rod stuff . whose a major supplier that manufacturer's the kind of rotor your talking about??

Guest Anonymous Posted January 10, 2001 Share Posted January 10, 2001 What kinda offset on the rotor? Give me some details and I can check my stash of fancy z31 rotors.... Just measure from, say, the stub axle flange to the center of the rotor, or whatever. I have a funny feeling one of the z31 units will be suitable. Also what exactly is the thickness on the z32 rear rotor? Lemme know so I can check a few possibilities. The required diameter would be nice also, but it's easy to turn a rotor down a slight amount if one can be found with the right offset. edit: also, you are using the flat maxima brackets, right? Not the unavailable offset brackets? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com [This message has been edited by Morgan (edited January 09, 2001).] Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 10, 2001 Share Posted January 10, 2001 just wondering where you are going to find a rotor with the correct offset to make it all bolt together?? Morgan i will take pics of the brackets i used its a VERY easy weld on.. the brackets i used are about 3/4" away from the bolt flange. i'll grab the oem ebrake and see how it works out too. but i never thought it was a easy thing to do. maybe using smaller rear shoes for the ebrake? ------------------ Mike mike@fonebooth.com http://www.fonebooth.com/brakes.html raceparts and brake upgrades.

Guest Anonymous Posted January 10, 2001 Share Posted January 10, 2001 When I say right offset, I mean so that it is a bolt-on proposition with the flat maxima brackets, z32 rear caliper, and whatever rotor. ie. it doesn't require spacers or anything like that. I don't mean for the parking brake assembly to work. But perhaps one could cut the parking brake shoes about 1/2 inch thinner so they would fit behind the axle stubs? Just a thought.... ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 10, 2001 Share Posted January 10, 2001 scca: how about a bolt-on bracket to fit the z32 calipers in the rear? danno: is the offset of the rotor/caliper correct, and it'll fit fine except for the rotor being slightly too large in diameter? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted January 10, 2001 Share Posted January 10, 2001 Morgan, I don't know about the Z32 rotor offset, it may be too large because of the use of the internal parking bake system but I will check it out for you tonight and report back. Maybe SCCA knows. SCCA, Your are correct in the cost factor, could be very high but what "good" brake components aren't - It's only your life or someone else's if you brakes fail. I don't have to tell you being a semi-professional race driver. I did look in the Coleman Racing Cat. and they have 7 pages devoted to rotors with lots of different offsets and diameters. They also have a custom rotor and hat design service if needed. I looked through both Wilwood and Baer catalogs and they also offer custom service and Wilwood must have over 100 different rotors for various cars. Will they work - I'm sure one or two will. In every major city ( In Denver for sure) there are hotrod and racing part stores. I was thinking of using a Ford rotor since I now have that bolt pattern. Out of the all the Ford vehicles available with disk brakes I'm sure a one or two will also fit my needs its just trying to figure that out.

Guest scca Posted January 10, 2001 Share Posted January 10, 2001 Danno, good luck.. and i mean it with the best intentions.. i am a dealer for coleman and they are one the best places to make rotors. but i dont recall ANY place making a one piece rotor vented with a hat. coleman charges about $160 ea for a HAT. plus about $100 for a rotor. all this for a measly 10" vented rotor??? spend the time to make your own brackets so the existing 300 rotors will work for them. Morgan, the problem is Supply/demand. getting a lot of these brackets made would likely be futile as there isnt a very large market for no ebrake. IF i was to make a different bracket than the max. one i would likely makeone to use with a new outlaw 1000 caliper as opposed to a used 300 one. i was playing with my car yesterday and i think i could hand make a pair of rear brackets for between 150-200 it would take around 6 hours to make a pair. if danno's able to locate a rotor that "bolts" on without mods then your both laughing ------------------ Mike mike@fonebooth.com http://www.fonebooth.com/brakes.html raceparts and brake upgrades.
