Wife's HHR has a typical newer (shoddy) GM steering column that rattles for no sane reason. Juddering front brakes telegraphed through the steering and was driving her nuts. I pulled the rotors. Roughly ground the outer rust ridge/ lip down with a grinding wheel, so it wasn't "sticking up" and going to catch on stuff in my next step.

Then I applied a wire cup brush in a 4" angle grinder. Went at it several minutes a side. Let the natural rotation of the grinder move things around. Then I rotated the rotor 90 degrees as my technique may otherwise lead to "high spots".

I did notice lines, that could be considered pad outlines, that somewhat, but not fully, were "erased". The first few seconds of "buffing" caused an immediate change/increase in shine, but I kept at it, not feeling satisfied.

Put the car back together, 75% better, I'd say. And the price is right.

The internet-speak is onto something, "warped rotors" may not always be.

Coincidentally, I never felt this in the brake pedal on this car. It was always the steering.

Pads and rotors were new a year and a half ago.

Were these 'white box' rotors, or something better?

A lot of "warped rotors" really are pad deposits.

I dont see that here. I can remember seeing i set of rotors with pad deposits in my life. We must drive like grannies around here.

Yeah. I replaced 20-some thousand mile factory rotors and pads in my Mom's Fusion for the same reason. I tried sanding the rotors, but didnt get anywhere with that; though I only recently got a grinder. I did it by hand.

It was the same way; all in the steering, not in the pedal. It got worse the hotter the brakes got.

Its weird how some cars love to chew through rotors and present you with steering judder or unwanted pedal feel.

I have had Centric rotors and Akebono ProACT ceramic pads on the Accord for 30K+. I'm not super easy and sometimes do brake hard. I always make sure to let the rotors cool/don't keep the brakes on after a hot/fast stop. Have in-between 2/3 and 3/4 of the pads left and braking is as smooth as the day they were new.

I think I've mentioned these before: for $40, they're one of the best gadgets a DIYer can buy.

I'm curious if the same result could be achieved by applying some acid with a brush.

IDK, the PO put them on right before sale. He was into lifting jeeps and could turn a wrench, but I could imagine using the cheapest stuff around on something he was about to unload.

How come you did not jack up the vehicle, start the engine, put it in gear and did a redneck on the car de-glazing of the rotors? Seriously, I am little confused as to how you could use grinder to get the rotor flat?

I wonder if a good break cleaner soak occasionally would keep rotors "clean" of pad deposits and extend life??

typically not, as they are literally welded on...

I did think of that. smile

I was concerned that due to the shape of my arm/ musculature I was bearing down more on 12 and 6 oclock than 3 and 9, or vice versa, so I twisted the rotor to make up for this perception of shortcoming.

I used a real grinding wheel/stone to cut the 3mm thick ridge on the outer perimeter down. Otherwise it would have plucked wire out of the brush.

I did something similar not too long ago on my wife's mazda 3, except a used 80 grit sand paper and a piece of 2x4 as a flat surface. However, the rotors and pads were glazed, but smooth operating otherwise.
