I have a Nissan Qashqui that has just had cylinder clutch

Resolved Question:

I have a Nissan Qashqui that has just had slave cylinder clutch and Dual mass flywheel replaced as my clutch pedal went down to the floor and did not come back up. 4 weeks later the clutch is slipping and the garage is saying that it is the master cylinder?

Hello there,

If your clutch is slipping, it could be just adjustment.

First please check the freeplay at the clutch pedal.

Should be easy for first 10mm, check with your finger.

If the pedal is heavy right at the top, it has no freeplay.

Master cylinders either leak at the pedal end, or bypass internally.

Which is what your pedal was doing initially.

I cannot check as my car is in the garage but the only change to my clutch was that bite to the clutch was very low on the clutch and then changed quite quickly to half way up. When the car is in 4th gear I can hear a rattle when I try to go faster

Sounds like two things happening here.

You have a noise and low clutch pedal.

They should pull the gearbox out in case the clutch pressure plate bolts are coming undone.

It might not be the master cylinder at fault.

You have a warranty on this from previous job.

They said that they have replaced the clutch but the reason for it going s because of the master cylinder. I presume my clutch would be under warranty still. Could this happen in 4 weeks and what should I be paying for
Expert:  HoldenTech replied 1 month ago.

The master cylinder could fail after a new clutch is installed, generally from new fluid flushing out the old, and then the cylinder leaks internally.

I have seen that many times, and is understandable.

I am more concerned with this noise that you describe.

If that is coming from the transmission area, then that is their problem to fix.

Did they use genuine flywheel, clutch etc?

the noise happens after the clutch slips the engine revs go up and then it starts to rattle so I presume it is the clutch. I do not know if they used genuine parts?
Expert:  HoldenTech replied 1 month ago.

Don't agree to the master cylinder until they verify the noise.

Possibly the clutch pressure plate bolts are coming undone.

This will cause noise and slipping clutch.

Hope this helps.
