Ok.. so its been going for a while, but now its gotten ridiculous.

Top up the fluid... go to work, wake up next morning and its empty again. Need the car for work so thats all I can do.

I have no idea where its coming from, but all the paint (I guess) is peeling off the chassis rail. So its leaking down, from the master cylinder.

Has anyone had this problem, my mate has the exact same problem.. So I thought if 2 of us have had it, surely someone else out there would have too , found and corrected the problem.

Thanks!

Adam. :D

have you inspected the cylinder for damage? is the reservoir cracked? all lines tightened well and not split?

i doubt an internal leak as its running down onto the rail.

Cylinder looks fine.. i thought it might be the grommets but they seem fine too. Im suspecting a single hose that I cant seem to find. :D

yeah master cylinder leak for sure.

with the engine off, put your foot on the brake hard. once the normal pedal movement is taken up the pedal should stay firm....does it slowly drop to the floor instead?

hmm seems i have this problem also. leaking between the big black round bit and the master cylinder (for lack of a more technical description haha)

anyone know whether master cylinders are interchangeable between r33 and r34? (i have an r34 GTT)

p.s. sorry for the hijack :D

Pedal is fine when I top up the resevoir, never sinks down to the floor.

Went to see a mate who is a mechanic today, he also tells me the main seal between the brake booster and master cylinder.

Im hoping its not too much, spose to be going to Sydney in a few weeks. :down:

Next question, are the master cylinders the same as r32/s13?...

Thanks everyone! ^_^

    • 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! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • 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.
