Expert friend came over today and installed new front KYB shocks. Before dismantling, he thought the old ones were good - but disconnected, they seemed to be frozen and hardly worked. He also tightened 6 bolts in the convertible top so much less rattles and car rides much better now on our bumpy back roads. Who knew top bolts had to be tightened? When he came back from the test ride, I went to move the car back to the garage but the clutch pedal felt "loose" and did not work. I had to pump it up several times to make it work. He had removed the aluminum cap and wiped it thoroughly to make it easier to remove and replace as it was corroded. Could that have introduced air into the system? I don't see how if the fluid level was full. Somehow air is getting into the system. The clutch has always worked perfectly in all the years I've owned this car. Any ideas?
