Default Dragging Clutch?

Peter, when clutches wear out, they allow the engine to over-rev when the car is being accelerated. This is called 'slippage'. As to 'drag', if your car did not have the clutch fully engaged you would have slippage. If you are experiencing 'drag', it just may be a wheel cylinder locked up in the apply position. Problems arise when you start swapping parts around from other brands. It would be best to have a specialist look at what is going on. You mentioned the fact that the pedal action has changed, and that may be due to the new clutch/pressure plate requiring more travel to disengage. In some instances, this can be adjusted out, if the linkage is mechanical. If hydraulic, then some serious bore sizes on master and slave cylinders would have to be addressed. Clutches are fairly straightforward, provided the right parts go in for replacement. Let me know what happens. ron

Thanks Ronald,
But this happens when stationary, out of gear. That is why I cannot understand what is happening.
Depressing the clutch pedal shouldn't have any effect, should it?
I don't think 403 clutches are hydraulic or assisted in any way.
Peter
