heres the story..

i bolted up the r32 gtst calipers and discs into my car.

Bled the brakes numerous of times and they just arent working, the pistons arent pushing the pad down, therfor arent grabbing the discs.

i bled through the lines, and then though the caliper.

Calipers had no fluid in them at all, is there any speacial things you need to do if they are bone dry?

could the calipers be sized and the pistons are jammed?

This is happing on both sides! :P

any idea whats wrong

thanks

Nate

Hi Nate, I'm not a mechanic but I have watched the job done by mechanics. Always bleed the longest line first progressing to the shortest line. Some mechanics also use a compressor with an adaptor and suck the fluid through the line. Also pistons can become jammed.

Did you check that the pistons moved before you put the callipers on the car? If not, check it before you go any further, just leave the brake hoses connected.

:( cheers :mrt:

PS; sticking used 10 + years old callipers on a car without having them serviced is asking for trouble.

You fitted the calipers to the correct sides of the car? Bleed nipple at the top.

You should be able to simply open the bleed nipple and let gravity do the work of filling the chambers - slow and tedious, but effective.

I wouldn't be surprised if the pistons were siezed in the calipers, though.

    • 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?
