S20001987

Hello, hope you are all well... I recently bought a new OEM clutch master cylinder for my 04 s2000, about almost a year ago, after the clutch lost all pressure and the car was not drivable. Now the same problem has occurred but this time I don't even see a leak under the clutch pedal nothing at all. I don't know if I should buy a new clutch or what...and it is completely dead now. Please help. Thank You

did you replace the slave cylinder when you did the master?

Can you describe what you mean by "completely dead?" Is it stuck to the floor? Does it have no pressure? Is it spongy with lots of play?

I only replaced the master I did not replace the slave cylinder...

It has no pressure, it is not spongy, i do not see a leak anywhere, my car has 133k miles on it, still on original clutch...

check the master cylinder reservoir for fluid. if there's no fluid, you have a leak somewhere. check behind the clutch pedal to see if there's a leak. i got a reman or OE from nissin/adler that leaked (got them replaced immediately).

if there is fluid, you likely did not bleed the system enough.

Did you thoroughly bleed the clutch hydraulics?

Can almost guarantee a blown slave cylinder. They can blow and not leak a drop. The internal seal wears on the slave and fails to build hydraulic pressure.
