This is regarding a VW rather than SKoda, but the part is the same. 65 plate Scirocco, under 40k. Pedal has the spring but then goes to the floor (no pressure). The car sees it's on the floor so it will start.

 

Why is this part plastic now, other than cost saving? 

 

I slowly feel VAG are shooting themselves in the foot. I'm seeing more problems on newer cars than ever before. 

 

Has anyone any other suggestions for what the problem might be, although it looks like the slave. 

Slave cylinders have been plastic on VWG cars for years, nothing new there. 

 

When they start to fail they usually begin to weep into the bell housing and attract clutch dust. On most VWG cars fitted with a full sized undertray the brake fluid that leaks out is caught and subsequently soaked up by the sound proofing element so it's difficult to actually detect. 

 

The best way to test it is to pressurise the system and operate the clutch pedal continuously then examine the underside of the gearbox. You might find a small drip. 

 

I've not seen them fail on the regular at all. I've done the first one for a long time earlier this week funnily enough.

 

I deal with all VWG brand cars on a regular basis. 

 

I changed mine at 120tkm,no sticky pedal,just drops under car
