Brake Booster Or Master Cyl Leak?

Hey guys i recently had an issue with my brakes. My standard handbrake is not bolted down so for about 2 - 3 weeks i had my hydraulic handbrake locked as the R32 was on a bit of a hill, Im assuming this caused the booster or cyl to die but im not sure. On the day i went to get the car tuned the brake master cyl was empty so i topped it up, The brakes worked but i had to push the pedal ALL the way down and there was no pressure, it felt like a clutch pedal.

I have removed the brake booster as shown in the pics below , i thought there might be a seal or boot or something that might have ripped under pressure but just by looking at the seals / boot they are not ripped or torn but as you can see from the pictures it is leaking somewhere, I assumed it was the boot behind the booster as when i pressed the brake pedal a few times i quickley ran to the front of the car and looked around the booster area and could see it leaking from behind but im still not 100% sure.

Any opinions ? Boosters are not cheap so i dont want to buy a new one unless i really have to but if i do then i will.

Mine did this the other week when I went to bleed them up (had front calipers off), I'm guessing it was a seal in the master cylinder and because the car has been sitting so long it ate through the seal on the booster as well. Picked up another master and booster from Steve May for cheap cheap :thumbsup:

The booster could be fine. They seem to be a lot more reliable than masters. If its not leaking air it should be ok. I believe that masters should be rebuilt every 10years (or some similar interval).

You didn't say that you bled the brakes after topping up the m/c. If the level disappears than proper bleed is necessary. Booster contains only air and vacuum so if m/c is leaking no need to change booster.

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
