Hi, my friend just bought a new clutch, and I think there's something wrong with it. We drive for about an hour on city roads and the clutch doesn't catch at all. The brand he got was ACT. He is in like 5th gear at 5000rpm's doin like 25 and won't go any faster, and we stop to let it cool off for 10 or 15 minutes. It is drivable for about 15 minutes after letting it cool down. Can anyone help us out. Someone told him that all he has to do is drive it around, and the clutch will break in. I think it might be B.S. because he's driven it well over 500 miles and I haven't noticed a difference. Any help is really appreciated. Thanks.
