Wondering Nomad Posted May 28, 2006 Share Posted May 28, 2006 I've read though the brake section but I'm still confused about the rear swap with 280ZX calipers and rotors. This thread says to use the FWD Maxima backets and the FAQ says to use the RWD Maxima brackets. So which is it? Am I missing something insanely obious? I just grabbed two sets or FWD rear brackets at the junk yard today. Are these the wrong ones for swapping the 280ZX rear calipers and rotors into my 72'?

RedNeckZ Posted May 29, 2006 Share Posted May 29, 2006 On the 280ZX rear brake package. The mounting plate is flat plate. The calibers are the early model (79-8/81) and the rotors are the later model (small hat, not the early version, wide hat). But the mounting plate is just a flat plate of steel 1/2". This is what I have in my Z at this time. But I know some poeple who has used 1/4" and 1/8" plate in their Z. The 1/8" plate was used by Mike Wilson, he had a article on it on the Internet Z club site. 1/4" plate was used by PParaska on his site. I also have a drawing around here from a GT-2 racer that used only 2 mounting holes to mount it to his car. You can conduct a search or look over individual's personnel sites to find out more info. :burnout: Link to comment Share on other sites More sharing options...

Option 1: 79-81 Rear 280ZX caliper 82-83 Rear 280ZX rotor 85-88 FWD Maxima rear caliper bracket (flat) Option 2: 82-83 Rear 280ZX caliper 82-83 Rear 280ZX rotor 79-83 RWD Maxima rear caliper bracket (not flat) Is that about it?

Chewievette Posted June 8, 2006 Share Posted June 8, 2006 Do you guys know or could maybe measure the diameter of the '84 300zx rotors for me? Thanks. Link to comment Share on other sites More sharing options...
Drax240z Posted June 8, 2006 Share Posted June 8, 2006 10.8" diameter or so. Covered in a few previous posts. Just FYI, mocked my 4x4/vented swap up tonight with my snowflake wheels. I will need a 3/8" wheel spacer to use the wheels without any grinding of the calipers. The brake clearance on the snowflakes is brutal. I could probably use a 1/4" spacer if I was willing to grind the fins/ribs off my calipers... I figure they are there for stiffness reasons, and it doesn't seem like the proper solution to me at this time. New wheels are in the works anyway, and I expect they will offer up a lot more brake clearance when I get them. Link to comment Share on other sites More sharing options...
Chewievette Posted June 8, 2006 Share Posted June 8, 2006 When its 2am and you have to be up at 6am it was more skimming than reading the last 100+ posts and I searched every page for "dia" and didn't find the info so, sorry. Thanks for the info. Link to comment Share on other sites More sharing options...
Zmanco Posted June 9, 2006 Share Posted June 9, 2006 Hi All, I asked this question at the end of another thread but never got a response, so I hope it's ok to ask it again here. Has anyone done the vented 4x4 toyota caliper swap with the later bigger calipers (S12W with 4 large pistons) and NOT swapped to the 15/16" master cylinder? I ask because I read that this was required for the swap for the non-vented swap, but when I did that and left my stock m/c in, everything was fine. I had no problem with a long brake pedal.

gearheadstik Posted June 9, 2006 Share Posted June 9, 2006 I have done this without swapping the stock mc.....but plan to swap to the larger one because the brakes didn't seem to be much more aggressive than the stock calipers were...in reality they might be but I'm not impressed so far by the upgraded calipers...hope this helped Link to comment Share on other sites More sharing options...
Zmanco Posted June 9, 2006 Share Posted June 9, 2006 ...the brakes didn't seem to be much more aggressive than the stock calipers were...in reality they might be but I'm not impressed so far by the upgraded calipers... Did you bed the pads in yet? The method I've used is to go out on a deserted road and accelerate up to about 60 mph. Then brake hard, but not a panic stop, down to about 5-10 mph. Gradually accelerate up to 60 mph and do it again. Repeat this 4 or 5 times. You want to get the brakes and pads good and hot, but not overheat them. Then drive the car normally to let them cool. As it has been explained to me, two important things are happening: 1. no rotor is perfectly flat, and this is speeding up helping to get the wear pattern on the pads to conform better to the irregular surface of the rotor. Assuming you have new rotors, this isn't something that is visible to your naked eye, but it happens and means that more of the pad will be in contact with the rotor. 2. some pad material becomes embedded in the rotor surface, much like racing tires leave some rubber on the track. This improves the tires grip, and for brakes, improves the coefficient of friction, meaning the brakes feel like they "grip better". The first time I ever changed brakes (new pads and rotors) I didn't know about this, and the first few stops felt worse than the old brakes. Eventually after several hundred miles of driving they broke in themselves. This process speeds that up. Link to comment Share on other sites More sharing options...
Guest grimlynsan Posted June 15, 2006 Share Posted June 15, 2006 i did the swap about a year and a half ago and havent upgraded the m/c yet. Link to comment Share on other sites More sharing options...
ZXRockie Posted June 26, 2006 Share Posted June 26, 2006 Just to let you guys know...the rear caliper from the 240SX are all the same...1989-199? S13 or 1995-1998 S14... from early model up to the 1998 model are all the same... Link to comment Share on other sites More sharing options...
toecutter Posted June 27, 2006 Share Posted June 27, 2006 Whats the weight difference between the stock front calipers and the 4x4 Hilux calipers? Link to comment Share on other sites More sharing options...
JMortensen Posted June 27, 2006 Share Posted June 27, 2006 Whats the weight difference between the stock front calipers and the 4x4 Hilux calipers? Surprisingly, only about 2 lbs per caliper. I was looking into that one a while back. I found a post where the original caliper weighed 9.x lbs and the Toy was 11.x lbs. Link to comment Share on other sites More sharing options...
Forrest Posted June 27, 2006 Share Posted June 27, 2006 Just as an aside, the 4 piston Wilwoods are approx 6.5lb. Link to comment Share on other sites More sharing options...
toecutter Posted June 28, 2006 Share Posted June 28, 2006 Well that certainly does'nt justify not having them! Especially seeing it's such a low cost and straight forward conversion. Sulio Link to comment Share on other sites More sharing options...
srgunz Posted July 2, 2006 Share Posted July 2, 2006 I just saw something different today July 1st at the SCCA Solo II national tour event. John Anderson's F Prepared Z runs the stock 240Z front calipers on the rear. The rear rotors are the solid rotors from the Datsun roadster. Goes to show what can be adapted to the rear of the Z.

mjfawke Posted August 17, 2006 Share Posted August 17, 2006 And a new option for the front. R32GTST front rotors (280mmx26mm), centre hole machined out to match the 260Z/280Z hub, diameter reduced to by ~ 5mm with Hilux S13W calipers. The calipers need a ~ 4mm spacer and longer bolts. Fits behind my 14x7 "kidney bean" wheels, but not behind my 15x7 three-piece wheels. Going to check out the 16x7 panasports next. 1 Link to comment Share on other sites More sharing options...
burntread Posted August 20, 2006 Share Posted August 20, 2006 Howdy all, When replacing brake lines with SS and switching to S12 calipers, do I get them for Datsun calipers or for Toyota? Do brake lines attach the same to any caliper and only the length matters? Just wondering! Link to comment Share on other sites More sharing options...
