got a front pair of stock gtr32 calipers i want to through on, Been sitting around for the last 6 months,

Who to see or what should i do to them?

get pistons checked, new seals, What more? not even sure what company does this thing or a standard brake and suspension place

I had GTR Brembo items serviced by Racebrakes here in Melb, cost around $170 or there abouts.

Just needed a clean/seals etc. Doubt it'll need new pistsons dude.

Although your brakes are the same as R33 GTS-t, you'd probably pick them up for $200 2nd hand :)

You can do them. Just pull them apart and clean them up - look for serious scoring in the bores or on the pistons and blow out the lines. Reassemble with the new seals and dustboots. If you Google there'e probably a few tutorials on the subject. Get a mate to help you bleed them properly (replace all your brake fluid while you're at it).

Its pretty easy. Just remove the nipples and buy replacements ones. Remove the rubber from around the pistons, there are some steel clips around them as well but if you remove it all slowly you wont damage anything. If the seals around the pistons crumble as you do it then it means they are shagged and need replacing. If they dont then they are good to go back in. Get some compressed air and carefully blow air into the bleed nipples. Be careful how you hold the caliper as you dont want the pistons to fly out and crush fingers. I normally pack the centre of the caliper with rages and then wrap a rag around the caliper to stop fluid and garbage blowing everywhere. Pull the pistons out....check them for corrosion etc.

Inspect the seals and re-assemble with PBR brake oil or just use liberal amounts of brake fluid.

Its all very basic stuff....I imagine there are some decent on line tutorials rather then rely on my 30 second sound byte which I have tried to type as quickly as possible :)

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
