Do I need a break job ?

Brakes

Wobble like this often means that you have warped or nonparallel rotor surfaces.

You would need to take a look at the pads on the front and see how much you have left. You may need to replace them (or not).

At the same time, you will probably have to have the rotors machined (or replaced) to bring them back into plane and parallel. If you dont do this correctly, you may have to re-do the job in short order.

In short, inspect them and find out what is wrong. Then fix them properly.

Thanks yes, "Brake job" ;) My Acura is 2004 @ 29K miles, so still under warranty, Do you think warranty is supposed to cover the rotor warpage fix ?

I think I have read on Acura forums before that people have the rotor job done at dealership and I *think* I read dealer didn't charge them.....

btw, what the heck exactly does rotor warpage mean ????

Rotors can have at least two distortional problems.

Consider the rotor as a disc which should be constant in thickness (rotor thickness is constant around the disc) and flat (as in a plane)

Warped rotors can occur because (1) too much heat is applied in braking and the rotor warps, (2) tightening of the wheel lugs is uneven and the rotor warps, (3) improper pad and caliper operation causes uneven wear etc...

If you have a variation in thickness of the rotor, then you will feel pulsations in the brakes when applied.

If you have warpage, there may still be pulsation upon braking, but you will also see other symptoms.

One way to solve these problems is to have the rotors machined on the car with good equipment. A good way to avoid them is to beat the hell out of any tire changer who approaches your car with an impact wrench.

No matter WHAT sort of system the impact wrench uses (Torq stix, etc) NEVER let a greasemonkey tighten your lugs with an impact wrench.

Sometimes you can index a disc to the hub to minimize out of round problems.

You also have to be very careful that your discs and wheel are installed onto clean surfaces and that the above mentioned distortions are minimized.

Look at the Babcox site for a good tutorial on brakes. I dont have the link anymore, but maybe someone else here has suffered less under Bill Gates that I have lately.

This is almost certainly the cause, since they never use torque sticks or whatever the add-ons are to air guns to get proper torque. However, if the tires weren't rotated at the dealer, the dealer may well say "tough luck" and bill the OP for the resurfacing....

It normally means the bozos at the last place you had the tires rotated used an impact hammer to hammer the wheel lug nuts on instead of a proper torque wrench with the intent of scamming you for a brake job you shouldn't need.

They (the scammers) will then offer a free 'turn' of the rotors to fix the supposedly warped rotors, so when you need a 'real' brake job, the rotors will be no good (too thin) and will be replaced on 'your' dime.

If you catch this early, lots of times loosening off the lug nuts and retorquing them on will correct it.

I believe this is the link I referred to earlier. It will explain a lot.
