Hard clutch pedal on Td5

Could some Td5 inmates here please have a wee peep over in the Defender forums at this thread?? My buddy needs help with a Td5 problem...or rather we both do as I'll be helping him

Basic troubleshooting: loosen the bleed screw from slave cylinder and see what happens:
1. if the pedal goes down then the problem it's with something connected to the clutch release lever which is blocking it.....u have to dissasemble it to see.....dont release the pedal before u screw ithe bleader back
2. if not its's from the hydraulic system......happened to me once, a small piece of rubber which went off inside the master cylinder clogged the hydraulic feed pipe(quite uncommon)......or the piston could be blocked
