Craig76z Posted December 11, 2015 Share Posted December 11, 2015 I just got the Toyota S12w calipers for my 78 280 and was wondering which fitting you guys are using. Is there a difference or benefit to using the banjo style fitting? Also if you could let me know the thread size on what you bought that would help too. Thanks in advance.

Miles Posted December 11, 2015 Share Posted December 11, 2015 (edited) The Toyota caliper was not machined for a banjo fitting. Consequently, the fitting will leak where it is attached to the caliper. Options: There are several companies that sell stainless steel braided brake lines of the correct length and with the correct Datsun - Toyota fittings. Try Silvermine Motors in the Vendors section. You can use A/N brake lines and an A/N-to-Toyota adapter to connect the Toyota calipers. This was my choice because I didn't want to rely on the availability of custom brake lines. There are several discussions about Toyota brake lines in the Brake Forum. Recommend that you spend some time researching the Brake Forum before doing the swap. Are you aware that you may have to go to a larger bore master cylinder with the S12W caliper swap? Stock well maintained brakes are fine for a street car. Stay away from so called "street performance" brake pads as they don't work well cold. If your car is going to be a street or daily driver you want a pad with good cold bite. Cold bite is what you need when a kid runs out in front of you. Quality stock brake pads work fine. See the Brake Forum for details on brake pads and brake swap balance issues.

Craig76z Posted December 11, 2015 Author Share Posted December 11, 2015 Miles, Thanks for the info. I have searched the posts, sometimes I find that there is too much and often conflicting information. I have the Wilwood M/C and am going with the 13" Earls performance brake lines from Summit. I just needed info on the fitting size into the caliper. By what you've written above it's an AN fitting and just to be specific it's a -3 correct?

SRRTz Posted December 11, 2015 Share Posted December 11, 2015 A generic AN line will not connect directly to the Toyota caliper. If you want to use a generic AN line, you'll need a 10x1.0mm male inverted flare to -3 or -4 AN fitting, depending on the size of your lines. I've got one car with lines from Silvermine and one with generic AN lines and adapters. Both work well and have never leaked, but I'll second Miles and recommend adapters and generic lines for the same reason he did. Quote Link to comment Share on other sites More sharing options...
Miles Posted December 11, 2015 Share Posted December 11, 2015 (edited) -3 TO 10mm x 1.0mm inverted flare adapter is required. See picture.

mforget Posted January 9, 2019 Share Posted January 9, 2019 Thread resurection....What length do you guys use for the braided flex lines on a setup like this (S12w) Im also wondering for the rear with maxima calipers.... Just want to order the right lines. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Miles Posted January 9, 2019 Share Posted January 9, 2019 I'll check the length for the front Toyota calipers tomorrow. Look here: covers front Toyota and rear 249SX or Maxima brake lines. Quote Link to comment Share on other sites More sharing options...
mforget Posted January 9, 2019 Share Posted January 9, 2019 Good infos there.... Thats pretty much what i came up with.... Would just need to know the right length for braided lines.... Im about to order 12" lines for both front and rear wich i presume would be ok..... Ill probably get those lines witht the 90 degree adapter at the end to connect to the calipers....

Miles Posted January 9, 2019 Share Posted January 9, 2019 I just measured the front flex line. It is 14 inches. I have relocated the rear hard lines so the flex lines are not in the stock location. You can use a coat hanger to mock up and estimate the length of the front and rear flex lines. After installing the flex lines move the suspension through the full range of motion and look for over stretch, kinking, rubbing etc of the flex lines. Flex line kits are available for the Toyota and Maxima/240SX swaps. I prefer generic A/N lines because they are cheaper than the swap kits plus I can get the parts from a local speed shop. Silvermine Motors might have the flex lines for the Toyota/Maxima swaps. Quote Link to comment Share on other sites More sharing options...

jhm Posted January 11, 2019 Share Posted January 11, 2019 Another tip when measuring for brake lines....if possible, add a couple extra inches to allow for the extra suspension travel when you drop the strut and control arms to swap springs/shocks/etc. Having a little extra length on the brake flex lines makes this job so much easier, especially on the fronts. 1 Quote Link to comment Share on other sites More sharing options...
