Brake Master Cylinder Stopper

I got a new front strut brace which incorporates a brake master cylinder stopper into its design.

Just thought I would post some feedback on the effectiveness of it.

As soon as I drove the car I could notice the difference in pedal feel. Instead of feeling a spongy/soft, the pedal is nice and hard. Also prior to fitting this I would get a slight vibration while braking. This is gone. I'm don't believe it alters the effectiveness of the brakes, but IMO is worth it just for the pedal feel.

I hope this helps someone :D

ps I don't know the thread of the bolts used to attach it (first question I had when fitting). some bolts I had lying around fitted :)

www.nismo.com.au have them for $99. they also sell a strut brace with built in master cylinder stopper (what i got) for $165.

Remember to mention that you are an SAU member to get your 5% discount :P

I went and got some new bolts (so they were pretty and matched). I took one of my other bolts along that fitted and matched it up to a thread tester which stated that the thread was (metric) 6 x 1.0 mm. The bolts I got were labelled as 6 x 40 mm (ie 40 mm long).

edit: 40mm is too long go about 25-30mm

OK people....speaking of the clutch master cylinder flexing....today the clutch hanger snapped the spot welds. The two bolts that poke through the firewall, if you look inside the car there is a bracket the clutch pedal hangs off with the studs for the master cylinder going through the wall... It popped the spot weld(s) on the left hand side of the bracket.

It now needs to be taken out and reinforced then put back in. It leaves me worried what will brake next when i put it back. Time to make the clutch stopper....

(ive got a OS twin plate clutch so its by no means a heavy pedal either:))

We have had the same thing happen to the R32GTST race car and it has an OS Giken twin plate in it as well:cheers:

unfortunatly no. As the bracket curves downward making cableties slip off as you push the pedal in.

I tried cableties, and using some small vice grips to clamp the bracket together. I was stuck at work in the carpark, and had to call a towtruck to get it home :D

don't cable ties fix this problem Gary :D

Yep, if you use enough of them and they are big enough. Plus you need to be able to lie upside down with your feet on the driver seat headrest and your head on the brake pedal for half an hour while you do it. All without throwing up. :wassup:

You have to use one cable tie over the front to hold the others in place. It took me quite a while to work it out, but we were at BATHURST and I wasn't missing out on a run down Conrod. :D

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
