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.

      Much less twat-tastic. CF wheels are too garish for civilised use.

      From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)

      In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
