hey guys its usually a simple task i know but ive emptied my master cylinder completely and now i need to rebleed the whole system since installing the r34 brembos and new braided lines. this is a wgnc34 stagea im talking about.

now i have the r32 gtr workshop manual (i only got the jap stagea one so its no use to me) and it shows u need to bleed the abs unit itself, which has 2 nipples on the top of it, but the stagea one doesnt and only has 2 lines on top, so how do i bleed the abs?

obviously the rest is easy and start from the rear left wheel, rear right, front left and front right last.

any ideas on bleeding with the 4 spot brembos which have 2 nipples on each caliper? do i just do the left front wheel first and do the furthest nipple first, then the closer nipple and then the front right in the same order (starting from furthest to closest)???

any info appreciated

thanks mate but i already have the 32 gtr manual and it doesnt tell u how to bleed the brembos and it says bleed from top of the abs unit nipples in which my stagea doesnt have any and has 2 lines on top of the abs instead that run to the master cylinder.

From memory working on commodores you don't actually have too bleed the abs unit it's done automatically when you bleed all the calipers. You just have to remember when changing your pads not to just push the cyliners back in as it backfeeds the abs unit and f**ks it...Might be the same with the 33's if the units have no bleed nipple on them....

No need to bleed the ABS unit just calipers, and long as you havn't removed or replaced the master you wont even have to bleed that. Its teh same as doing a brake fluid flush, you suck the reseviour dry and just refill it then flush the lines..no need the bleed the master.

If you do run into trouble however you can do a pressure bleed on the master by cracking the lines while you have a helper pump up and hold the pedal.

R33 ABS unit is probably bled with the consult/scan tool electronically

So what's the trick to get the pistons back into the calipers safely when ABS is fitted ?

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
