Solutions to the clutch pedal sinking on my Maruti S-Cross

I've had the clutch pedal sinking twice while driving - thankfully at slow speeds.

BHPian ballkey recently shared this with other enthusiasts.

I have a 5 year old S-Cross 1.6. The car has relatively been trouble free, but in the last 1.5 years has not seen too much mileage. I do take it out at least once a week for an hour or so.

I've had the clutch pedal sinking twice while driving - thankfully at slow speeds. Both times I have been able to lift up the pedal and continue, but I am really worried on this. It drives reasonably well and there's no loss of power when it is working.

Any likely hints on what could be going wrong? Previous forum posts on other vehicles have indicated everything from full clutch replacement to master/slave cylinder replacement etc.

Appreciate any information on this.

Update: I took it to MsM Chennai - there appears to be some oil leakage, indicating slave cylinder failure. The service advisor says the entire clutch assembly needs to be replaced including the flywheel, about Rs 55k.

The service advisor says slave cylinder failure could have leaked oil inside and the plates could also be affected. I have asked him to inspect thoroughly after lowering the box.

Here's what BHPian abhishek46 had to say on the matter:

The classical symptom of a failing master cylinder is the erratic behaviour of the clutch pedal. For e.g. the clutch will sink and not return back.

Get the master cylinder checked.

Here's what BHPian sagarpadaki had to say on the matter:

Unless the clutch plates are covered/contaminated with the hydraulic oil, there is no need to change the clutch. And flywheel will not get impacted with a leaking clutch slave cylinder. Just get the slave cylinder replaced and bleed the clutch and you should be good to go. Be with the service centre when they open the clutch housing to check if the hydraulic fluid has seeped inside and over the clutch plates.

Here's what BHPian scorpian had to say on the matter:

Get the gearbox opened in your presence and check the plates for oil. If contaminated then there is no way other than replacing them.

If not contaminated then you could just have the slave cylinder replaced and have a good system bleeding done.

Usually, service centres insist on complete replacement, as it's a labour intensive job to remove the gearbox etc., so might as well replace all components at once.

Not required for a low run car to be honest.
