release bearing snapped in half

picture should be here--

My clutch slave cylinder top part after removal from the car. The release bearing has had it's lip shear off completely and the rest of the clutch was forced through the fingers of the clutch plate, to rattle about inside the clutch/dmf unit.

Needless to say when it happened the car suffered instant and total loss of clutch pressure, and I had to get home with no clutch at all. Fortunately I was able to start the car in first gear to get going.

I fitted that slave cylinder (euro car parts) only 4 months ago, and have done only a about a 1000 miles. Why did it break?

I was able to make a hybrid of the old slave cylinders release bearing and plastic floaty bit and the newer undamaged cylinder and piston hydraulic parts.

It's so much nastier to repair the car in the freezing cold and heavy rain, but the car is now back together and the gear change works now.

Fluid must have gotten onto the clutch plate because take up of drive has been juddery since the rebuild. I think the judders are less severe now as the fluid burns of the plate.

I may fit the clutch kit damper as this may reduce the pressure changes in the slave cylinder to prevent the same thing happening again. Any thoughts on this?

The cheap 'Lucas' branded kit from ECP has given lots of issues, and I'm seeing a few LUK slave cylinders failing too (especially recently).

Which brand was it?

There was a discussion about the clutch damper kit a good while back, the consensus was that it served absolutely no purpose.

It was an attempt by Rover to address complaints of clutch judder.

I think the original purpose was to reduce noise/vibration from the clutch in diesels. It was a cause of problems itself.

At the very top of the OP it says '--

I cannot see a picture either.
