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 :)

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P

      Help Understand GTT Boost Setup

      By joshuaho96 · Posted

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.
