New Brakes
|
|
|
I put new brake pads on my 2007 F-150 FX4, not OEM, but still nice brakes. After installation, I noticed that my right front wheel makes an audible "whoosh" sound as I drive. It's not obnoxiously loud, but it's there. The brakes are not squeaking. In fact, they are working better than ever - but I can't seem to figure out why the wheel makes noise as a I drive. What could I have done while replacing brake pads to make the truck do that?
Any help/advice would be greatly appreciated.

If all you did is just pads they are probably getting messed up with the old rotor on rust that the old ones didn't hit if this happened exactly on doing front pads only,

Thanks Tom. That could definitely be it. I have already lubricated everything (twice), so I know it has to be something like what you suggested.
I should also mention that I have not yet driven more than 150 miles (and haven't been over 40-45 MPH) since I installed the brakes, is this noise going to go away when the pads wear down or am I going to have to replace the rotors?

Hope it didn't wreck the new pads just to start over again with this,

When you do your brakes, its always needed to have the rotors turned. If not this type of problem will happen. If the machine shop does their measurements and determines they are worn too far to be turned you get new ones, which aren't as expensive as they were back in the day. Your pads have a break-in lining on the outer surface that needs the rough surface of a turned rotor to properly bed in for maximum braking force. If it doesn't get that, it won't bed in properly. You may never notice it until that one time where it counts, like a kid chasing a ball into the street. Then those few feet matter the most. Thanks for coming here for advice and I hope it helps. Brakes are the most important thing on your car and need to be perfect. They are easy for a DIY guy to do but the small details can also make it easy to screw up. We are always here to advise you on the best ways to save the labor costs at the shop for items that you can handle on your own.

Tom, thanks for all the help, but I am not sure what solution you are suggesting? Is this something that will go away once the new pads "mesh" with the rotor, or am I in need of new rotors? Thanks for all your help - I appreciate it.

There's quite a range of prices and qualities for rotors. On trucks it might be practical to have them turned and checked for thickness. When a new pad is put on a used rotor is doesn't match nor break in well and can burn in one area and ruin new pads again as said.
The pads need the rotor to have some roughness for a good break in as Nick said. Brakes are NOT a good place to try to save a buck or you can just play ping pong and need this whole job again.
Ages ago when real asbestos (softer material) was common they would mould to each other fairly fast and don't do well with that anymore,
