BCNR33 Vs BNR34 front brake caliper threads

Hi,

I have a set of R33 GTR Brembo front calipers.

They came without the hard lines or any brake lines or fittings but do have the "olives" still on them.

I wanted to retain the factory flared hard lines so i bought a set of BNR34 hard lines with aftermarket braided lines since both BCNR33 & BNR34 share the same part numbers in both Nissan & Nismo data.

I tired fitting them to the calipers but they do no't seem to fit due to a different thread on the caliper and hard line bolt,

Do BCNR33 & BNR34 front calipers have different threads?

Thanks!

Yes mounting bolts are different.

Mebbe....but I think he means the thread where the brake line goes into the caliper.  I don't know if they are different but I would have thought 99% they are they same. Maybe see if a tap in the thread cleans it up

[Hadouken]

Agreed. Everything else should be the same other than the bolts that mount caliper to car

I bolted standard R32 GT-R lines into the R34 Brembo (front), so it shouldn't be that hard. Unless your R33 has different brake lines?

I did mean the thread where the brake line goes into the caliper.

Anyone knows what thread tap should i use? threads don't look dirty honestly...

I'm starting to suspect the previous owner tapped the calipers to a different thread since no one encountered such a problem.

There's a limited number of thread types and sizes used on flare nuts.  Do some googling and edumacate yourself.

You also need to get the alignment perfect for those hardline fittings.
