Hello,

I have a '99 1.8 Standard model is use for trakdays and autosolos. The rear brakes have binded since i bought it, with a spongy pedal and fronts that are far too keen to lock.
I also bought a '04 euphonic as a parts car, which didn't go too well as it doesn't share a whole lot with my NB and has the rubbish LSD. Only good news is i've made a fair bob from selling bits from it.

So i thought to save money id rather swap the big brakes from the euphonic onto the NB, whilst gaining some heat capacity and stopping power. Apart from the fact ive now had to spend hundreds on new calipers/discs/pads/hoses I've now hit another issue.

To get the correct pedal travel and feel i need a 15/16 brake master cylinder, the NB currently has a 7/8 one. Now, I thought, great ill swap it from the euphonic. No dice, euphonic has ABS (2 ports), NB doesnt (3 ports).

Now what i need to know is: Whats the part number for the correct 3 port, RHD 15/16 master cylinder? and where can I get one? from what i can find only the US has alot of these non ABS cylinders in the right size, but they're obviously LHD!

Help would be appreciated, running out of time before my next autosolo!

Good point actually, I've got the tools just need to order this and get to work.

I need to swap the servo over from the euphonic too, right?

Thankyou, I will give it a go. You don't happen to have a picture of the modified master cylinder lines do you? Trying to think of the best way to do it

Great thankyou, did you use the existing proportioning valve or go without? Alot of people are suggesting to get rid of the proportioning valve completely

So I've fitted the t piece, but for the life of me I can't get the bloody thing to seal. I'm using all original brake pipes so shouldn't be the flares.
Any advice?
