Rear Gtr Brembo Query

[JoELMaN]

Hi all,

I am trying to find out if the olive at the bottom of the brake line thread on R34 rear Brembos is removable/replaceable.

Can anyone shed some light on this?

Thanks in advance.

They are removable, but they can a bit of a pain to do so. I had to remove mine to facilitate the fitting of my braided brake lines.

To remove them without damaging the internal thread, I screwed a large screw into it and gripped the screw with a slide hammer to ensure it pulled out square. I know most people will think the slide hammer is overkill, but it obviously didn't take much to get them out, just a slight tap.

Good luck.

Thanks for the reply. That's exactly what I wanted to hear!

Did you end up running a banjo fitting?

I use side cutters, but it gives the same outcome, they just slide out. Once that's gone you can use the Banjo fitting.

No worries.

My Project Mu brake lines didn't have a banjo, but rather a male flare fitting, which is why I had to removing of the standard olive. The olive converts the brembo fitting from a male to a female type.

I also used copper washers to aid sealing.

Cheers guys. Ideally I would like to replace the damaged olive as I have HEL braided lines to suit the r33 gtst rear calipers I currently have on the car, but if I have to change to banjo fitting(s) so be it.

Up to you but there is no way I would run a front brake line perpindicular to the caliper like that. Recipe for disaster ... unless you have done something that isnt obvious to ensure its not going to shear with suspension travel and lock

[White GTS-T]

That's at full lock with full droop and that's the 'tightest' the line goes through the suspension travel. There's still plenty of length. Here's full lock the other way.

But you're right, and the modified knuckles do exacerbate the problem slightly.

[JoELMaN]

Has anyone removed the olive without damaging it? I'm trying to chase down a replacement before converting my lines to banjo bolts.

Self tapper shouldn't damage them if you are careful...
