R33: 2 Brake Fluid Reservoirs?

There is a small reservoir on the left hand side and towards the back of the R33 engine bay that says its for brake fluid.

The adjacent larger brake reservoir specifies DOT 3 brake fluid only on the cap. But the smaller reservoir doesn't specify any DOT standard on the cap.

Would I put the same brake fluid in there as the larger adjacent brake fluid reservoir?

Why are there 2 brake fluid reservoirs anyway?

Can I use the same brake fluid for the clutch as in the brake fluid reservoir?

What brand would you recommend? It says use only DOT 3 on the brake reservoir.

See link below for pic of reservoir in question.

Whatever is cheap, it can all be mixed as each DOT specification is chemically compatible. As long as you don't get DOT5 which is silicone based, DOT4 or DOT5.1 is what you want and both superior to DOT3 (I doubt you could find DOT3 anyway)

If you are chewing through brake fluid, then you might have a leak somewhere in the brake lines, pinhole leak in a rubber hose for example.

I thought my clutch fluid reservoir was empty but it turns out the fluid in there is really translucent. Is that normal? It's a different colour to that of the brake fluid.

You use the brakes more than the clutch, brake fluid can get up to and perhaps beyond 250C under heavy conditions on the road (easily 300+ at the track) as it absorbs heat from the calipers, discs, and pads whereas clutch fluid just acts actuates the engagement of the clutch. So that's why clutch fluid stays the same color, whereas brake fluid will blacken over time.

      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.

      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
