I had most of the brake system replaced. This week a caliper was leaking and on the way to the mechanic it was idling unusually high. When I press the clutch all the way down it would idle at 2000 rpm. If I take out the clutch in a stop position it would go back down to where it used to idle. It is hard to keep i that way until I start to drive.They replaced the caliper and test drove it but when I drove it to work it did it again and and kept doing it. Anybody have any ideas? I appreciate any help and thanks in advance. Also thanks to those of you who gave me ideas on the brake line.
