Bob, not sure how to describe it. I just asked Karen and she said it feels like a chatter in both the break peddle and steering wheel when she applies the break. It is very slight at 25 but very prominate at 45 or 50. ----- Original Message ----- From: "Bob Kennedy" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, August 14, 2008 10:48 PM Subject: Re: [BlindHandyMan] question for the car guys
A long shot but I bought new tires once and had a bad vibration right afterwards. When I got home I popped the cap off and found the problem right off. The idiot put the lugs on backwards so the tapered end faced away from the wheel... Diagnosing by email is much harder. By vibration we need to get a bit more specific. A warped rotor doesn't vibrate at 25 to 40, it feels more like jerking. A smooth run, a jerk or bump and a smooth run again. The bumping or jerking gets slower obviously as you slow down. I could happen, especially if the rotors got turned too thin the last time. I've known some um well idiots is really too nice a word. But I've known of people that read the specs on the brake lathe and think that is what the first cut should be. If the lathe says it can cut 90 thousandths in one pass then by god that's what you have to do. 90 thousandths off any rotor will put it under the minimum. If it is thin and slammed home with a tire gun they can warp fairly quickly. Not a couple weeks I wouldn't think though. I have known the outer pad to be put on without either putting the anti vibration glue on, or not bending the tabs to keep the pad tightly in place. Those situations cause a vibration that is often loud as well. When the brakes are applied you hear sometimes a squealing or a humming type sound. That isn't nearly as dangerous as it is annoying. But since it started after brake work, I'd take it back and see what they offer. One thing you can do on your own is to take a wrench to the lugs and make sure they tightened them all. 1 left loose won't cause a serious problem, I have had to run a race car on 3 lugs on 1 wheel before. But that isn't the brightest way to go. Take a torque wrench if you have one and 75 to 80 footpounds will keep the wheels on. If you don't have a torque wrench, take a socket or something and make sure everything is tight. ----- Original Message ----- From: "Lenny McHugh" <[EMAIL PROTECTED]> To: "handyman-blind" <[email protected]> Sent: Thursday, August 14, 2008 6:43 PM Subject: [BlindHandyMan] question for the car guys > We have a 2003 grand caravan sport all wheel drive.
