I have several crazy things going on with my car. I changed the front pads and turned the rotors and rotated tires. The front tires are now worn pretty bad in the middle. I have had more brake dust on one side than the other and the caliper slide pins are working fine. The mechanic said the rotors were good and not warped. I have a humming noise at 30-40 mph that goes in and out like when the tire is turning only. The car also feels like it is pulling and letting go back and forth like something is warped on the front and it is touching and then not touching. I have checked the temp on the calipers and they are equal on both sides. Tires both turn well when jacked up too. I have taken it to 2 places and no one knows.

does the car jerk back and forth or from side to side?....if the tires a wearing mostly in the middle that means there slightly over inflated....

one caliper could be slightly pulling harder...

if its back and forth that could have nothing to do with the suspension...my car kinda jerks back and forth on coast, but thats because the car has the fuel shut off and it just does that...

I have the slight jerk that you may be describing. Mine only does it at idle in 1st gear. I believe its a bit of slack in tbe drivetrain. I don't think its hurting anything.

mine does the same whem i cruseing and i let off the gas.for the tires i say to much air.depending on the wheel id say about 32-34psi is best[for my car any way]

I have the jerking, too. It happens more when I have the AC on. Sounds like something isn't right. It also sounds like its brake/tire/wheel related, so it couldn't be that hard to figure out.. especially for a shop. Good luck.

Sounds like one of your calipers is messed up in some way.

Have you checked the brake fluid level to see if it's letting any go? (i.e. maybe leaking at the piston seal in the caliper)

Brake fluid level is not going down and it is dry on the brake hose.

U can have a brake hose that is collapsed inside the hose that u will never see. Also you can have a sticky piston in the caliper. But I dont think your problem has anything to do with the brakes at all.
