Checked the master cylinder resoivoir which has very little fluid in it.(92 r32gtst)

the pedal is super light and i need pressure back so i can drive it tomorrow to get a new clutch installed.

i found this tutorial at 10w40.com is it applicable?

Follow this procedure to properly bleed the hydraulic clutch which is similar to bleeding brakes.

1) Top off the clutch master cylinder reservoir.

2) Put a clear plastic tube on the bleeder nipple and submerge the end of the tube in a jar with some clutch hydraulic fluid.

3) Slowly depress the clutch pedal.

4) SLIGHTLY loosen the bleeder nipple.

5) While fluid is traveling through the tube, tighten the bleeder BEFORE the pedal is fully depressed.

6) Release pedal.

Repeat procedure until you are certain:

A) No bubbles appear in the fluid stream.

B) The bleeder was opened after the clutch pedal started depressing and was closed before the pedal reached the bottom.

C) The master cylinder reservoir never uncovered the ports in the bottom.

Make sure the slave cylinder is tightly fastened to the transmission case and does not move when the clutch pedal is depressed.

Look for threaded adjustment rods in the slave cylinder and clutch pedal linkages that can be used to insure the clutch is fully released BEFORE the clutch pedal is fully depressed.

my car is low,will i be able to reach the slave /bleed valve without getting fully under the car?cheers.

You can reach the slave cylinder just by reaching under the car (no need to jack up or take tyres off)... my car is stock suspension (r32 gtst) but i still think you'll be able to get access. If in doubt get a qualified mechanic to do it.

It's not really that difficult, especially if you've got a friend to push the clutch pedal for you. Bleed the master, then the slave.

Still, if your reservoir is low you'd be best to find out where the system is leaking and then replace as necessary - especially if you're going to the trouble of getting a new clutch.

Be careful as the damper in the clutch line setup could cause problems. The is a small box located beside the chassis rail, it also has a bleeder nipple on it. You will most likely have to bleed it from there also. The person operating the pedal will need to use their hands because the pedal won't return by itself while bleeding. Don't attempt to do it yourself as you will cause problems.

Oh, and don't bleed the master unless you are replacing it.

and you dont really need to submerge the other end of the tube in fluid, just make sure you close the bleed nipple before the pedal is pulled back up again so air doesnt get sucked back in thru the nipple

      TPS voltage RB25DET

      By BASHERnissan · Posted

      Hi guys my TPS voltage is reading over 2v at idle.  My Haltech ECU is reading around 40% throttle position at idle also which is really strange. Note the actual throttle position sensor is brand new…    anyone have any experience with this or know how to calibrate it on Haltech ?

      Cas issue

      By joshuaho96 · Posted

      The OEM disk will not work on any AEM ECU, you need to use the one they made. You shouldn't have to flip the CAS or whatever you were describing, if you set the ignition sync offset correctly it can't backfire. Make sure you're using a spark plug lead on coil 1 instead of the timing loop to avoid weird issues with the timing light. Double check that your timing settings are actually correct, like is the 24 tooth configured correct or should it actually be 12 teeth for 1 crank revolution? I also found this: 305817248-AEM-Undocumented-Settings-v1-2.pdf

      Yeah, I don't believe the M35 uses a deadhead system.

      Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.

      Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).
