jschiff_g8 Posted April 4, 2016 Share Posted April 4, 2016 Out of curiosity what Master Cylinder are you using? What about the Brake Booster? I believe it is just the stock 280z master along with the stock booster. Quote Link to comment Share on other sites More sharing options...
Miles Posted April 4, 2016 Share Posted April 4, 2016 I believe it is just the stock 280z master along with the stock booster. Pedal throw a bit long? Quote Link to comment Share on other sites More sharing options...
Phantom Posted April 4, 2016 Share Posted April 4, 2016 You may have a couple issues. The original 280Z master cylinder is designed to work with drum brakes in the rear. Your tear disks will continually drag if you don't change it out. Research it on this forum. Secondly, the disc brakes have larger Pistons so use more fluid that the stock disk/drum set-up. You need to at least upgrade to the 15/16" master cylinder used on the 79-81 280ZX. It is slightly larger so will push more fluid and is designed to work with disk brakes in the rear. Sigh - more to do in your future. Quote Link to comment Share on other sites More sharing options...
jschiff_g8 Posted April 5, 2016 Share Posted April 5, 2016 Pedal throw feels alright, still haven't tried bleeding it again. I thought I might need a new master, I emailed gabe back and forth and he said it wouldn't be needed, but I really want do another thorough bleeding and get some drive time on it. Thanks for all the info if there is anything you guys want me to check I will be working on it tomorrow! Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 5, 2016 Share Posted April 5, 2016 Is it possible to get the bleeder on the bottom with the Wilwoods? I notice in your pictures that the "d" is up on end (front or back), and the "w" on the other. If he plumbed the front and rears differently and you got the calipers swapped, you'd have a bleeder position problem. On the stock system, the calipers will swap side to side and cause that problem.

JoeK Posted April 5, 2016 Share Posted April 5, 2016 Is it possible to get the bleeder on the bottom with the Wilwoods? I thought we wanted the bleeder screw at the top, so air bubbles would escape easier. Do I have that backwards? Quote Link to comment Share on other sites More sharing options...
jschiff_g8 Posted April 5, 2016 Share Posted April 5, 2016 There is 4 bleeders on each caliper. 2 on top and 2 on the bottom. You are only suppose to bleed from the tops. Also I believe you are suppose to bleed from the outside in when it comes to the 2 bleeders on top. Also start with the caliper furthest from the master ( right rear). Hopefully that answers your question. Thanks Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 5, 2016 Share Posted April 5, 2016 The bleeder should be at the highest point of the internal passages of the caliper. That's the basic principle. Some people tilt the caliper, I imagine you could tilt the car to get the same effect. Whatever it takes. Bubbles rise. Be the bubble.

nullbound Posted April 5, 2016 Share Posted April 5, 2016 Also I believe you are suppose to bleed from the outside in when it comes to the 2 bleeders on top. Also start with the caliper furthest from the master ( right rear). Since the S30 brake lines run on the passenger side of the transmission tunnel, the left rear caliper is technically further away from the master in terms of brake line length than the passenger side is. I generally start with the left rear for that reason. Quote Link to comment Share on other sites More sharing options...
duragg Posted June 26, 2016 Share Posted June 26, 2016 Installing my new T3 Big Brake kit front and rear on the race car this weekend. I had the big "plate" style early 280zx calipers in the back and the new T3 setup is a lot more pad area and 6lbs less per side (12 total rear weight loss). Up front I had the S12W which have plenty of stopping force and never faded with 660 fluid, ducts and DTC60 pads. But the new T3 setup will get DTC70 pads, ducting and is about 15 pounds lighter per side!! That's 30 pounds less unsprung weight in the nose. And a net loss of 40 ish pounds on the car? Might have to check my classing sheet again!! Many thanks to Gabe for dealing with my annoying questions too Good dude. Supposedly a decent pilot also TJ Quote Link to comment Share on other sites More sharing options...
kona41 Posted July 6, 2016 Share Posted July 6, 2016 I would love your input RA240z and OldAndyAndTheSea I am putting together my set up, and before I install the wheel bearings would love to know if I have the caliper bracket installed correctly in these photos. I have the recess of the bracket facing out. I have mocked it up with caliper, stub axle and rotor, but just want to be sure, because I am not sure how the hell I could get the bracket off and flipped with the stub axle installed with out pulling out wheel bearings...... wicked thanks in advance Photos in the google link below. I will post up more photos of the install of this kit. https://goo.gl/photo...MkmKpiGa1tEzx76 Quote Link to comment Share on other sites More sharing options...
loy Posted July 6, 2016 Share Posted July 6, 2016 (edited) Recessed part should face inwards. You can install/remove it without removing the stub axel. Also, How long have you had the kit? At the beginning the mounts sent out were incorrect. I had to get the modified bracket sent to me. http://i.imgur.com/s24wrNG.jpg Edited July 6, 2016 by loy Quote Link to comment Share on other sites More sharing options...
kona41 Posted July 6, 2016 Share Posted July 6, 2016 I think it arrived last summer. Much more milled down then the bracket in the picture that wasn't worked. I will flip them. Makes sense. Much appreciated. Quote Link to comment Share on other sites More sharing options...
