Brake Master Cylinder Leaking...

Its been happening for quite a while now, was fine when driving the car... just topped it up and all was well. Can see it peeling the paint off the booster.

Since defect it sat for 3 weeks, (completely forgot about it) which gave it long enough time to completely empty itself. Now with air in the system, brakes are useless.. So cant drive it to get repaired...

So my question is, should I just take it off & get the seals redone? Or is there more to it then that. Or just buy a completely different unit? Anyone here that can vouch for a place to do it? Was going to just bleed the brakes and put new stuff through it, but seeing as its gonna do it again anyway.. might as well do it once, and do it properly. :)

I would take it off myself, never really looked at the thing so just wondering if its an easy task...

Thanks.. much appreciated. :)

Adam..

both, i could be wrong and R34's for some reason are stupidly expensive, but to give u an idea i paid under $100 for mine in the 32.

i deal with all clutch and brake down here in SA, maybe try them and see if they can send u something.

i just rang nissan here in brisbane they want $460 for a R32 new brake master cylinder and around $190 for a rebuild kit

i'm a bit weary of the rebuild kit though, i really can't be f**ked pulling it apart once to see if it has scoring along the barrel then trying to put it back together so i can drive my car in the 10 days i need to wait for either one depending on the condition of the barrel to come from Japan

Still have the baggie, it was sitting in my rubbish for when I clear away that area..

protex 210J0159 is what is on the label.. Make sure it is the 1" master, and I can't remember if it was the nabuko or tokiko, think it was nabuko..

Remove the master cylinder, pull it apart, follow the workshop manual, easy as.. make sure everything is sparkling clean, you don't want any little bit of dirt getting in there. after you remove the piston assembly you can shine a torch in there and you will be able to see if there has been any corrosion, contamination, scoring, etc. In my case it was just old seals that lost tension.

Brakes are better than they have ever been. Transfer case clutchpack decided to die shortly after as well, never ends.

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
