Brake Fluid Leak...

[AdMan]

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!

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.

Its the rear seal. Never done one on a Nissan, but at work we usually replace the whole master cylinder. 2nd hand isnt all that expensive.

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

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.

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

Thanks everyone! ^_^
