I'd like to know why they didn't wear evenly. maybe the caliper piston was coming out at an angle (worn piston or cylinder) or hanging up on one side, causing it to push the pads at a weird angle.

Make sure that before you put the new pads on the glazed rotor, you take a 3M Scotchbrite pad to the rotor and get it all nice and cleaned up. So the new pads can seat properly.

I will clean up the rotor properly. I had done that with the front wheel a couple months ago, I took the wheel off and then the rotors off and clean them off nice with a soft metal brush.

the way the pads are wear, it would be like the rotor as a V shape ?!!!!... that doesn't make sens. also the pistons can't really come out on a side. and if even one side was coming that way that would not make the other side to be exactly the same... at least I don't think so...
now , let's talk about something that's is easier, what type of engine oil is better, synthetic or not ?...hahahahah

If you have a micrometer or calipers, I'd check the inside/outside thickness of that rotor. Pads wear on the rotor just like a car (only not as bad)

Another thing you can do is remove the caliper from the mount, and push on the pedal until the pads just come together and see if the pads are flush on the pistons. If so, then you know that the pistons are coming out crooked. For some reason the two pistons aren't coming out straight like they should. Or the pads aren't tracking straight when squeezed.

Screw it, buy a new caliper/pads/rotor and be done with it. :-)


Synthetic/Non-Synthetic isn't as bad as the WD-40 as a chain lube controversy.

I was kidding about replacing parts. If you need some help checking it out you can bring it by my house and I can help trace down the problem. Unless it can't be moved.

As for the WD-40 conundrum, forget I even mentioned it.

Find out why the pads are wearing funky, and you'll find your problem with the dragging brakes.
