Hey Guys,

I have a 1992 R32 Skyline GTS-T with RB20DET.

When driving sometimes the clutch will suck down to the floor , i pull it back up with my foot and its fine for sometimes 10-20 minutes of in town driving or it can go 2-3 days.

but sometimes it will do it 3-5 times in a 30 min span.

I have replaced the clutch master cylinder and the clutch slave. and the system is properly bled.

what could it be?

Chrischeezer · 03-28-2013, 08:19 AM

do you notice any fluid in the car, under the clutch pedal?

trickey1991 · 03-28-2013, 08:28 AM

Nope everything is dry

Chrischeezer · 03-28-2013, 09:04 AM

did you replace the clutch master and slave for this problem? or another?

trickey1991 · 03-28-2013, 10:06 AM

Yep replaced both

If this thing is falling to the floor like its leaking... chances are... something is leaking...

are you loosing fluid over time?

Could be your throwout bearing?

trickey1991 · 03-28-2013, 12:23 PM

no fluid lost/

Mine does somthing kind of similar, i have only replaced the clutch and slave, MC is next along with a SS braided line.

But try this and tell me if its the same too

"Set you hand on the clutch pedal and barely push, Mine slowly falls all the way to the floor",

as if there is an internal leak somewhere. I cannot find clutch fluid leaking anywhere however. hopefully we can help each other and figure this deal out

If pedal is soft. Fluid is escaping/air is getting in. Otherwise if properly bled the pedal will be stuff due to force from pressure plate and pressure built up inside the lines(when depressed).

So fluid is leaking externally. Or internally, past the seal made on either master or slave when put under pressure.

Please anyone chime if this is wrong. But this is my thinking based of my knowledge of hydraulic systems. ESPECIALLY one this simple

Tho I bet u got air in the system. Bleed that thing real good. Those soft lines directly from master to
Slave make it much easier

I cant remember now but does the R32 have the same shitty dampener loop as S-chassis? If it does, is that shit still in there? If it is, it probably still have air in there...

trickey1991 · 03-29-2013, 09:22 AM

Damper is removed, and the pedal is stiff as Shit, it doesn't fall to floor if slightly pushed Hmmmm
