I was refilling my tires with air today (gotta hit that 35/33psi mark!), and I noticed that my rotors were wearing unevenly. I've got slotted/cross drilled rotors (they were installed when I purchased the car), so it was relatively easy to see the difference. The passenger side's slots were damn near ground down flat. The "slots" have more or less turned into slits. The driver's side, however, are still looking like slots.

But here's the weird thing, my driver's side rim is always the dirtier one when I clean the car. It's noticeably dustier (I use the Axis Ultimates).

Lastly, brake pad wear looks very similar. I haven't had a chance to dismount the brake pads to give a better examination, but looking through my rim spokes, it appears that the wear is nearly almost the same.

What do you think could be the issue? I'm thinking a stuck caliper, but wouldn't the passenger side be making more dust if that was the only issue?

 

Touch the dirtier wheel after a good drive - mine was almost too hot to touch when my caliper was sticking.

Wouldn't it be too hot to touch regarless after driving and braking?

The wheel itself? Warm, but not roasting. Assuming normal driving and not brake-bedding style driving.

I'm thinking you are right, but could be either side on a floating caliper design.

 

You can still get caliper rebuild kits from the dealer if it is stuck. I dont recall the part # off hand.

 

Just make sure the slide pins move freely.

And if there are any torn boots then get the rebuild kit like suggested above. You do not want water inside that pin. Thats just asking for rust.

 

Verify that it is a sticking caliper or slides as said above. If it is the caliper open the bleed screw and try to push the piston in , if the piston goes in now it is the brake hose.Cover your bases before you spend money

 

i have a similar issue, my front passenger wheel is noticeably dustier than the driver side, and the brake caliper paint is burned more on that side. i've checked the pins and the piston, no problems there. i'm stumped
