I recently took my 06 torrent to my mechanic for a problem I thought was with the brakes, possibly the ABS. The car on occasion makes a loud whirring noise and the brake pedal sinks slightly while sitting stopped. They told me the problem was the alternator, which they are repairing under warranty. I have never heard of an alternator affecting the brakes. Would this be a related problem to the alternator or possibly something else. Any ideas? Thanks.
