F50 or f40 is the Ferrari variant they were originally designed for.

They are no better than any other brembo calliper.

The good about them is that they will accept a decent sized rotor (355-370mm usually)

they are radial mounted so easy to fabricate adaptors for.

Good supply of pads in most name brands

realativly cheap in comparison to gtr brembos etc.

I would debate that. They are better then Nissan OE BRembo calipers by a long way. (but whilst they are better in many ways the on road difference isnt huge) They are better then the Brembo Lotus caliper and all the other lesser model 4 pot Brembos that only take 28mm thick rotors etc. They were the premium street/road caliper before the range of 6 pot and 8 pots came out. I still think they are the better option over the silly 6 pot and 8 pots.

But re your other points i agree

ive been looking round for em for a while now, they seam hard to come by

Roy should be able to sell you one his many different brake sets he has, if not then put you in contact with someone brake underworld to get some.

Everyone knows he is a brake whore ;)

...LOL, I am pretty tragic at buying brake setups. Though i have tried all the F40/50 combinations now with different rized rotors and dont have any at the moment. Which made my heart sad which is why i considered these... http://www.skylinesaustralia.com/forums/Br...html&hl=f50

I still think that the F40/50 combination are hard to beat for value and performance on a well sorted car. Truth is the std Nissan gear does a bloody good job with the right bits, but sooner or later with enough power, and grip then cars can do with a bump in brake hardware

But how are they better than the 33/34GTR or the lotus ones? Physical size gives it stiffness, piston size you can choose to an extent, rotor size you can choose, they don't have piston cooling features or made of titanium, no external cooling or other "features".

Features aside because you can look at a caliper and see the features, and china calipers copy everything anyways, what makes A brembo better than B brembo, or A caliper better than B caliper?

Well what makes it better is does it suit your application?

I got some F40's from Roy's house of brakes & they are good. Why?

Because the radial mount & bracket allows me to use the calliper on different rotor sizes as what I want to run changes. So in other words if/when I want to schlong a bigger rotor at the thing I can use the same calliper, albeit with a bigger bracket. Also the mount allows you to do the same in regard to different "depth" rotors.

Aside from that the pad is bigger & is infact the same size as they use on GT Falcon's etc with Brembos (BA's anyway). So every man and his dog have them available.

- External bridge for better fluid cooling, ie out in the breeze rather then in the caliper boiling.

- They accept a ticker, therefore generally better cooling rotor (32mm vs 28 or 30mm)

- The variety of rotors they accept means you can normally pick the qty of vanes you run so can go a bit heavier in the rotor for better cooling and kinder more street friendly pads

- They are more rigid, so better pedal feel

- Radial mount, so can be taken from car to car, based on the coin they cost you may as well keep them for your next car, just with new bracket and hat offset

- Larger pad area so run cooler

So they do have features that mean they run cooler. The titanium type pistons that you are thinking off are generally race only and dotn have suitable seals for lots of street driving. Racey calipers are fin on the street if every 5,000kms you whip them off and clean the build up and gunk from them.

Anyway, i love my F40/F50s. Will soon be trying some Stoptechs out which will be interesting how they differ

I went from standard Brembos (R33GT-R) to F50's and there was huge difference on the track as far as bite, and they did not give up after a lap like the standard Brembos did. Although I was running 355mm rotors and some Pagid RS14 pads on RE55's. They did not show a hint of giving up even after 4 hard laps, the tyres let go instead. Since then I went to Alcon 6pot 365mm with 4pot 330mm rears which were better again.

Since then I have upgraded again, and YES I do have a fetish for brakes as does Roy, and there is no cure for it... :thumbsup:

f50,and f40 calipers are diferant.

f40 suited for 343mm f50 355mm disc.

f50 has 40 and 44mm pistons

f40 has 38 and 44mm pistons

ive used f40 ones. they have been on fire and still were fine. the seals were still mint. good caliper.

I guess I was thrown off by all the randoms claiming they have "f40/f50" Brembo brakes but when I looked at them they looked nothing like what I've been accustomed to. I then thought f40/f50 was more of a family of calipers rather than a specific caliper in the Brembo range but it looks like not everybody knows what they're talking about/what they have.

Yep I see all the good things about them and again, I want some! :)

This is an F40 calliper. To the best of my knowledge it looks no different from an F50 - piston areas aside. It does look and is different from the Brembo's found on the R33's etc & from the current range of Brembo callipers.

Also to the best of my knowledge there is no difference between an F40 & an F50 pad (Which in turn is the same as a Brembo equipped BA Falcon, oddly enough).

Lastly I am not aware of there being any difference in the rotor sizes that these callipers can accomodate ie an F40 can go on a 324 rotor (like mine) a 343 rotor or a 355 rotor. As can an F50.

Pretty sure F50 can go bigger than 355mm rotors, F40 biggest rotor that it can take is 355mm rotors while F50 can go up to 378mm? somewhere around there

p/s: I still havnt got those caliper brackets made up, only a couple of places in Perth do 3D CNC for that diagram you sent me

Do you guys know if anyone sell these radial mount bracket or can make one up?

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
