Scott Posted September 11, 2011 Share Posted September 11, 2011 Sounds to me like the ABS connections over at the passenger side are mixed up. Could be wrong though, I've got one to install as well so I look forward to seeing how you get on Quote Link to comment Share on other sites More sharing options...
TT Paul Posted September 11, 2011 Author Share Posted September 11, 2011 abs connections?? maybe but it says the rear pipe on master cylinder on instructions Quote Link to comment Share on other sites More sharing options...
Scott Posted September 11, 2011 Share Posted September 11, 2011 Over at the ABS unit on the passenger side. The 2 lines from the master cylinder connect to the ABS unit, from there 4 outputs lead to the 4 corners. Rather than them being paired in axles as they should be they have been paired in sides.

TT Paul Posted September 11, 2011 Author Share Posted September 11, 2011 strange why has it locked front and rear though so pipes on abs need swapping then?? Quote Link to comment Share on other sites More sharing options...
Scott Posted September 11, 2011 Share Posted September 11, 2011 strange why has it locked front and rear though so pipes on abs need swapping then?? It's locked the front and rear because something after the master cylinder isn't setup right. I'm guessing it's the pipes leading out of the ABS unit that are the wrong way around. It should be fairly easy to tell as they will be crossed over at some point. This has nothing to do with what you have done with the line lock unit btw. This is just a mixup that has happened in the past. Quote Link to comment Share on other sites More sharing options...
TT Paul Posted September 11, 2011 Author Share Posted September 11, 2011 ok i.ll have a look thanks for the help Quote Link to comment Share on other sites More sharing options...
JustGav Posted September 11, 2011 Share Posted September 11, 2011 Hold on.... Need to be careful with this, as it sounds like the master cylinder has dual feeds (which rightly it should have).... I've not looked into too much detail at the supra braking system recently, but I understood from the basics in mechanics that there should be diagonal opposite systems, ie front right+rear left and front level+rear right to help mitigate any failure issues....

Every line lock I've seen connects to the master cylinder as the OP has it. What I don't know is if everyone ditches their ABS when they do this or not?

dude Posted September 11, 2011 Share Posted September 11, 2011 it does have dual feeds Gav, front and rear IIRC. Every line lock I've seen connects to the master cylinder as the OP has it. What I don't know is if everyone ditches their ABS when they do this or not? The line lock is plumbed correctly, never seen this result before so Scotts conclusion is prob spot on. I do have a ABS delete kit if its needed !!! Quote Link to comment Share on other sites More sharing options...

TT Paul Posted September 11, 2011 Author Share Posted September 11, 2011 chased a few pipes swaped 2 over linelock working. just need to bleed brakes.. Quote Link to comment Share on other sites More sharing options...
Scott Posted September 11, 2011 Share Posted September 11, 2011 Good stuff. Its actually good you found that. Losing an axle of braking would be tricky, losing a side would be extremely dangerous. Quote Link to comment Share on other sites More sharing options...
mellonman Posted September 11, 2011 Share Posted September 11, 2011 why have you gone for a line lock in a auto? Quote Link to comment Share on other sites More sharing options...
Scott Posted September 11, 2011 Share Posted September 11, 2011 why have you gone for a line lock in a auto? What difference does auto/manual make when burning up the rear wheels? Quote Link to comment Share on other sites More sharing options...
JustGav Posted September 11, 2011 Share Posted September 11, 2011 Good stuff. Its actually good you found that. Losing an axle of braking would be tricky, losing a side would be extremely dangerous. Pretty much instant spin.... We used to train people to handle this at BMW advanced driving, by disabling the ABS and then two wheels on the skidpan and two on the tarmac, and it was frightening JUST how quick the car can turn round on you....

mellonman Posted September 11, 2011 Share Posted September 11, 2011 What difference does auto/manual make when burning up the rear wheels? well with a auto you can just put your foot on the brake and power through the rears and light up the tyres all you want with only a slight move forward. but with manual its abit harder to lift the clutch and press on the throttle and brake at the same time.

I've done it on ice and it's scary. I didn't catch it, I wasn't even close, I reckon I could do it 100 times and still not catch it lol.

Scott Posted September 11, 2011 Share Posted September 11, 2011 well with a auto you can just put your foot on the brake and power through the rears and light up the tyres all you want with only a slight move forward. You can do that with a manual too, it burns out your rear brakes though and isn't good for any part of the drivetrain. Queue boiled fluid, gummy rear pads and short lifespan on everything. If you're going to do a job, do it right Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted September 12, 2011 Share Posted September 12, 2011 So how the hell did the OP's brake lines get crossed in the first place? I deleted the ABS unit on mine a fortnight ago and I can confirm that the car had a dual circuit system , front axle and rear axle as opposed to the diagonal lay-out of some cars. I have a new line lock kit to fit as well, just in case I'm finding I can't kill the W58 quick enough on a track. Quote Link to comment Share on other sites More sharing options...
