1 tuff z Posted April 20, 2009 Author Share Posted April 20, 2009 seems like everything else has been getting done lately except my z. anyway, was bleeding [or trying] brakes this weekend and discovered the master was leaking. yet another task to complete. had a new one in my parts stash, installed and bled. bled the brakes and ready now for a drive to bed in the new rear pads & rotors. of course what is the weather doing for the next few days-rain...aargh! first pic is the completed assy awaiting wheel/tire install this pic shows a bracket to keep the ebrake cable away from the rotating parts. i used some heavy stainless bar stock [laying around in my friends machine shop and he made quick work to fab them for me] and installed them using the stock hard line mounting holes nissan provided on top of the hub assembly held on by a rubber lined hose clamp. seems ok to my practice engineer mind. checked clearance from compression to extension with the floor jack and all is clear. should be able to [hopefully] drive it this weekend to bed the pads/rotors and assess the brake bias with the new rear brake kit. also need to adjust the parking brake...

1 tuff z Posted May 5, 2009 Author Share Posted May 5, 2009 ran into a snag when bleeding...bad master cylinder. replaced the master, but for some odd reason did not install the prop valve. first test drive, a wee bit too much rear brake. so, get the proper fittings and installed the prop valve today after work. my loving wife agreed to get her occasional right thigh workout and helped me bleed the brakes. nice firm pedal and away i go on my test drive. spent some time on the phone with john coffey last week to pick his automotive brain as to the best way to dial in my brake bias [many thanks i now owe john - most likely i the form of cold brews when we meet in person some day]. so, filled the tank with gas and will over the next day or two get the plan that john detailed for me. after the brief drive today to retrieve my son from soccer practice i turned the prob knob a turn to begin the fine tune bias process. more later...

1 tuff z Posted May 12, 2009 Author Share Posted May 12, 2009 so, got the bias nearly adjusted to where i want it. need a few more laps around the track to verify it's current position. was at watkins glen this past fri-sun but didn't get too much track time [behind the wheel] as most of my time was as an instructor student. the local bmw chapter hosts an annual its [instructor training school] and it pretty intensive. so, i am very happy to report that i am officially a graduate of their school and instructed my first [official] student! back to the brakes. i ran the z for a few laps to about 8/10's and she ran wonderfully. i am very confident that my current brake setup is the deal. good stuff - i can go to any parts store and buy off the shelf pads for front or rear [street pads of course] if i'm in a bind. same goes for the calipers. rotors are a different story for the front-custom sourced from mml. rears are mustang and need to be drilled for the z lug pattern-not too crazy. current setup consists of; Front - modern motorsports [mml] front 13" rotors [i believe they are coleman] on a custom alum hat. pbr aluminum 2 piston floating caliper [common in older c4 vettes and mustang cobra & r's]. Rear - mustang calipers & rotors [08 version for the gt & gt 500] from silvermine motors. rotors are drilled for the z 4 lug pattern. master cylinder - 15/16" from 79-81 280zx on stock 73 240z booster. proportion valve - installed inline for rear brakes. stock prop and safety valves removed. i can honestly say that the customer service from edan at silvermine is top notch. there were a few bumps along the way [as you have seen in the thread] but he took care of anything that came up that was less than advertised-at his cost. i would definitely purchase his mustang rear brake setup again knowing about the quality and great attitude on doing things right. my plan is to run at least 2 more track events and log more time on the current setup and post more comments here. i anticipate that the info i post will only verify what i have written so far. the best part, when you buy from edan-he is always a phone call or email away!

MoNkEyT88 Posted May 13, 2009 Share Posted May 13, 2009 Wow, those rear caliper mounts look great.. Mine are rusted. Zinc plating didn't hold up. Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted May 13, 2009 Author Share Posted May 13, 2009 mine were not originally plated. the machine shop told edan that the material they used for the brackets would NOT rust. who were they kidding-themselves? mine began to rust on the way to ny from cali... i had them plated locally. once edan discovered the problem he had the remaining brackets plated. Wow, those rear caliper mounts look great.. Mine are rusted. Zinc plating didn't hold up. Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted June 3, 2009 Author Share Posted June 3, 2009 update-spent monday & tuesday lapping watkins glen at speed. knocking down sub 2:20 lap times on street tires. car felt great. had to make a slight adjustment to the prop valve [heard the rears squeak a bit deep into braking on the back straight bringing it down from about 145mph]. the new brake setup has continued to perform very well. rotor temps are now much closer, front to back [unlike the great desparity i had previously]. i logged a bit over 5 hours on the track. zero brake fade or any other brake issues. i am very happy and believe that this is all the brake i will ever need for my z! rags and evilc were also there, clive was running joe's newly acquired ls1z [dale mx's old z] Quote Link to comment Share on other sites More sharing options...
