Im looking to do an upgrade on my brakes without spending too much $$. Currently I am running DBA 4000 rotors (the old directional design) with stock rears and unknown pads / fluid I was giving it a pretty hard workout at happy laps today at the end of the QR straights and after about 20 mins pedal went straight to the floor - just went at turn 6 without indication :O not a fun feeling, somehow managed not to come off the track using some hand brake and gears and let it all cool off.

Just before I had the pedal at the floor moment I noticed vibrations under heavy braking from about 160km/h - Kind of like driving with warped discs haha

After it had all cooled down 10 mins later pedal was fine and vibrations gone with pedal being nice and firm again. I am unsure if this is a pad / fluid / disc issue, I don't want really bitey brakes as I do not have abs I would rather something progressive with good feedback.

Any recommendations what I should be doing? Would it be simple as a fluid change?

Sounds like you boiled the brake fluid.

At the very least get QFM A1RM pads and DOT5.1 brake fluid. Add some ducting as well.

Don't skimp out on brakes, especially brake pads. I had no issues with using Super DOT4 brake fluid, although that was on my N/A R31.

      Questions on potential new purchase

      By latino_R35 · Posted

      Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers

      Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.

      Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.

      I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.

      Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust
