Well, I am starting a whole campaign of overdue and preventative repairs on my car so I thought I would jump on here and see what you all had to say about one of my issues. Within the past week or two I have been hearing a rather loud humming noise from my brakes. I think I have managed to localize it to the passenger front corner. The odd thing is that it only happens when braking during a left turn and it doesn't always occur. It seems more likely to occur at speeds greater than 40 but I have had it happen a few times at 30 and less. braking in a straight line or right hand turn never causes this to happen. As of yet I haven't even looked at it so it may be something as simple as a loose bolt allowing for some vibration but I don't know. Is it possible that the slider pins the caliper rides on are worn and if so why would it only act up in a left turn? The car has 128,000 miles on it but the brake pads and rotors are only about 25-30k old. Any advice would be greratly appreciated.
