For a long time there has been a slight pulsing in my brakes when stopping and moving from 20-0 mph. Lately, however, when going down a hill or using the brakes for a while then stopping, the pulsing is very pronounced. I am assuming this is a warped disc since my pads look like they are still thick enough. Any way to figure it out? Any way to figure out which disc is warped, so I can know to replace the fronts or rears? Second, I think I must have got some grease or dirt on the discs while changing out my springs because now there is a metalic low-key squeek from the brake(s) when moving. I can only hear it when I have the windows open and when I am close enough to something that will reflect the noise, and when I am slow enough that the other sounds don't drown it out. So it is not loud or really annoying, but it is there now, and was not before. Can I use just normal brake parts cleaner and or compressed air? Techniques? Things to do or not to do? Thanks | ||

Bailey, I am experiencing the same exact thing. When/If you ever find out LET ME KNOW!!!!! My pulsing has got to a maximum and is horrible now, and the squek can only be heard if i roll the windows down i can hear it just before i stop, worse sometime more than others. Let me know if you find out. rover7592@yahoo.com -Garrett | ||

To identify the problem you clamp a dial indicator to the brake caliper and measure the out-of-true on the rotor as you turn it. You can feel any amount more than .003 inch. You'll probably find .020-.030 on the really bad ones John www.robisonservice.com | ||

Yeah, sounds like a warped Rotor. Chances are the constant squeek you are hearing is the warped rotor coming in contact with the caliper/pad as your wheel makes a revolution. John's comment should do the trick. If your rotors have never been turned and they're not too bad you might try that. Although having the rotors turned (re-surfaced) makes them thinner and more prone to warping. If you've got the cash I'd replace the problem rotors. Also while you’re into the brakes check your calipers to make sure one or more isn't sticking. This could be part of the cause of your warped rotor. A stuck caliper will heat up the rotor and cause warpage. Hope this helps, Chad. |
