Hey fellas, im about to purchase EP3 calipers from breakers as theyre quite cheaper than FN2. I would need bigger splash guards (fn2 ones) and new set of disks and pads. Am I missing anything else for complete swap?

 

You don't need bigger guards you can bend the existing ones clear of caliper and disc, I believe the fn2 ones don't even fit without modding in any case.

since fitting mine I feel like I have brakes, far more feel therefore more confidence in them over oem, I wouldnt go back now if a new set was given to me.

 

It wasn't just snake oil. The bigger disc diameter increases stopping torque even if the force applied is the same. Also you can use pad compounds that are not available for the derv set up. In my opinion it is a good cost effective upgrade for a standard derv which is fitted with barely capable brakes from the factory.

Thank u for support mate. [emoji106]

I changed to CTR calipers on my derv. Was that just a snake oil [emoji24]

I've put the diesel caliper piston back in now I was only seeing if I could use the seals and piston as a temp while my new set came, but there all different completely unfortunately,

The EP3 piston was 54mm diameter and 56mm in length

The diesel piston was near 55mm diameter and I didn't measure the length but it was roughly 20mm longer

I'm surprised. Is the EP3 same as the FN2? I remember the derv caliper being just smaller all together. But I don't have both of them any more for a comparison. Maybe you could post the piston diameters here?

 

I've had them both out today in my hand and I was about to post but my outcome was different lol,

The diesel piston was bigger by 1mm diameter and a lot longer than the EP3 piston, I didn't measure

The FN2 brakes are poor IMO. I'd look into another way to upgrade!

 

This is a bit of an old thread, sorry to bring some life back into it, but I know the EP3 piston is 54mm I'm pretty sure the FN2 is the same, due to the calipers being almost identical, did anyone find out if the diesel piston is the same size?

Diesel pistons are smaller.
I did a lot of brake comparisons in the past for upgrading my Derv to either FN2, Brembo or Stoptech 300mm touring kit, as I had a sample of all of them.
Can't find the stats I wrote down now but the FN2's have much larger pistons. Shame I've lost them meant to post them up ages ago. :facepalm:

 

i take your point as the fn2 is lighter so less stopping power required.

 

If the piston sizes are the same on type r and 2.2 diesel then the clamping force is the same. Therefore there is not much more braking as you are only talking of 18mm difference in disc diameter?

 

Even still the larger discs + larger pads = more connected surface area = greater stopping power

If they werent much better, then why would honda spend lots of money developing slightly bigger ones??

 

Thanks FAHAD for your input. I have purchased the type r accord calipers and just need to sand blast paint and then get a repair sal kit for them. The carrier is the same as a civic type r carrier should will fit the hub.

Does anyone know the piston size of the type r civic piston compared to the stndard diesel caliper piston?

 

Pretty sure its same mate,

 

Do it mate, in my honest opinion its well worth it!

And Im only running standard CTR pads & discs, If you were to get some drilled and/or grooved and some EBC or Ferodo pads then would be even better!

The s/s lines are also well worth it, no sponginess and a progressive feel to the the peddle.

 

Ah, I never realised that the CTR calipers were single piston..

Coste is right though, although I can't find the link anymore, I distinctly remember back in the days when we were running THAOC, one of the Irish lads fitted CTR calipers to his 7th gen Accord... so there's a strong chance those twin piston calipers from the ATR will fit - just make sure you get the carriers with them mate!

 

EP3 Front Calipers & Carriers - 300mm - EK9.org JDM EK9 Honda Civic Type R Forum so ep3 calipers are the same as ctr calipers therefore the accord twin pots should fit.... i take no responsibility if they dont though!

 

tdi might know?

 

Honda Legend Calipers - EK9.org JDM EK9 Honda Civic Type R Forum now you need to know if ek9 calipers fit a fn2

 

see what you can find mate, see if anyone on the accord forum has fitted ctr brakes

 

Thanks for your replies.

Sorry I meant 300mm discs not 320mm. I wonder if the twin pot calipers are the way foward then?

I wonder what modifications are needed to fit the diesel civic?

 

Twin pots would be good considering the sticky caliper issues.
If they fit over the FN2 disk and use the same mounting points.

Hoses is the differnce between the brakes suddenly vanishing after 5-10 mins of abuse or 30 minutes of abuse
Othe rthan that they just give you more accurate brake pedal control.

 

Still single piston and 300mm on the ctr i reckon the twin pots might fit though.... Some on ebay 180 buy it now

 

Not sure on the Civic but on the Accord I went from standard single piston front calipers over a 300mm disc to twin piston Accord Type R (Nissin) calipers over the same 300mm disc... and the difference is staggering!

I can only imagine how good it is moving from a 280mm disc with presumably single piston to 320mm? and possibly twin piston.

 

It depends on what you are after the ibitial cold bite is what i wanted and what i now have btw xtr are only 300mm
