R33 Gtr Front Caliper Hard Lines Part #'s

[alonroz]

Hi,

I got a set of R33 GTR Brembo front calipers.

Unfortionaly they came without the hard lines.

Anyone knows what are the part numbers for these?

I came up with these two but i'm not sure they are right:

46245-24U00

46246-24U00

Thanks!

Be careful, if they came without hard lines the "olive" has probably also been removed from the caliper.

There are 2 ways to fit brake lines, either flared hard lines (like factory) that have a matching flared olive inside the caliper, or just using a banjo bolt and copper washers.

Most aftermarket kits use the second as it is simpler and cheaper, so depending on your application you may not need the hard lines at all. Also, you might be able to find them second hand because most people throw them away with conversions

Thanks for the help,

Sorry for the stupid question in advance, if the flared olive is indeed missing i should be able to tell by looking inside the rear bolt on the caliper?

Yep, and in an unusual stroke of luck I have one of each type of caliper here. You need to look closely inside where the brake line bolts in because the fitting is at the bottom

Basically, the top type expects a brake line with a banjo bolt and copper washers, and the middle/second type expects a flared fitting like the 3rd pic. You need to work out what brake lines you are using to decide if your caliper needs to be the first or second type. In each case I've tried the fitting in the caliper is removable if you need to convert to banjo type.
