Thats a normal problem especially if you have had a leaky slave cylinder. It will soften the clutch friction material and will fracture and fly off. Im sure your bellhousing was full of material and dust too. I keep the Centerforce clutch from Ford racing in stock if you want a better clutch. That kit would run you $173.80 and a slave/release bearing would run you $74.07. Or i can get the complete kit from ford for $180 and that includes the release bearing/slave assembly.
