I'm currently having a CNC Staging Brake installed in my X90.

A few things we've learned so far:

- The X90 brake line fitting thread pitch is M10x1.0

- The CNC staging brake comes with standard 3/16" fittings, so you'll have to get metric M10x1.0 fittings or use 3/16" to M10x1 adapter fittings

- The front port on the master cylinder is for the rear brakes and goes to the front fitting (inlet) on the handbrake

- X90 brake lines are not like anything stateside. I thought they might be like the SC or GS but looked up the diagrams and they're similar but different

- The X90 brake lines are complicated as f*ck due to the traction control and abs

I'll post more and pics later.

Yeah, it came with fittings on the handbrake but I need the thread pitch for the fittings that will go from the master cylinder to the handbrake. I did a bit of research and it looks like the brake fitting thread pitch is M10x1.0

Oh I will, Mats! I'm surprised you're still using the stock handbrake.

I updated the OP with some useful info. Hopefully, the handbrake will be done in a week or so.

My friend/mechanic called yesterday and said the handbrake is in and works great! The only other problem he ran into was the lines I gave him were too long, so he had to cut and re-flare them. Oh well, I'm glad they were too long rather than too short. He's finishing up a few things like painting the mouting bracket. I should have it today or tomorrow and will post pics.

I have nooooo idea. LOL

You could always buy shorter brake line. I bought 5 foot just to be safe, but 3 feet is probably closer to what you need.

Yeah I have mixed feelings about Hydro's, I installed one on my E36 and really wasn't that much better than the drum ebrake that I had before. It was just in a better position to pull it. It is a staight up motherfucker to bleed. I feel now if you want to do a hydro right you gotta use seperate rear calipers. The benfits outweigh the extra effort in my mind.

You probably didnt size the cylinder on the hand brake correctly and if running a pass through setup there is no extra steps to bleeding... you just bleed your rear brakes like normal... I feel like people over complicate things sometimes its really a simple concept

Dual rear calipers are for pro cars. This setup works fine and some pros still use it. Dual calipers aren't worth it when all you're doing is having fun with friends.

Well im just speaking from experience here. If I still had my e36 I would be going to a dual caliper setup.

there is an unwritten agreement between all manufacturers of hyrdaulic pass-through master cylinders that they all need to have really stupid fitting sizes and not come with the fittings.

the fucked up inlet fitting on the wilwood pass through is scary as fuck. i've never seen the correct fitting that could properly fit it, everyone always runs a sort of next best thing that they have to dig up because wilwood didn't supply the magical unicorn reverse -AN fitting that doesn't exist.

such a giant liability for a brake part.

You won't be saying that when the system locks up on you... Maybe you'll get lucky and won't have a problem but I've seen it happen enough on quality single setups that I'll go ahead and have a machine shop fab up a dual caliper bracket.

^I actually will be saying that if/when it does. I maybe do one drift event a month during the season. It's not worth it to spend tons of money on a dual setup when all I'm doing is fucking around with bros and not trying to bust 100+ MPH entries.
