New Brakes, did I make a mistake?

Hey guys, I just replaced both the pads and rotors on my car. check out these pictures of my front and rear brakes:

Rear:


Front:


Notice that they are both only wearing on the outer diameter of the rotor. Why is this? Have I forgotten something? The only thing I know I forgot was to lube the guide pins when I had the calipers off. Can this cause the uneven wear?

Thanks for the help!

^^ yes, if you havent lubed the pins it could be binding causing the pad to drag on the rotor.

Take it apart asap.. Lube the pins and if you have boots over them make sure they're in food shape so no crud gets into your grease -- I also do the edges of the pad where it slides on the caliper bracket

Thanks guys, that's what I thought. I've only driven 100km on them or so. Will do them properly today.

I also do this. I lube where they make any contact with the caliper/bracket.

Cool! Make sure you use real brake lube too because they get HOT and some lubricants won't stand up

Update: I've removed, cleaned, and greased all of the guide pins on all brakes. The fronts seem to be wearing properly now, but both rears remain unchanged. I have no idea what may be causing this now.

rears will probably need a bit more time. give it a few days and recheck them.

car is braking/safe. So dont fret

If you put some heat in them they may even out try a few hard stops to bed in

Looks like everything is put together fine, if someone was wrong you'd know right away and probably hear weird noises.

The rear pads probably need to seat properly. Did you do any type of Pad/Rotor Bed in procedure?

Anti-seize is the stuff I'll put on the sliding surfaces between the pads and the caliper bracket. I use a synthetic silicone-based grease for the guide pins. I've heard that people use anti-seize for the guide pins too, but I'm not sure if this is the best practice or if will cause any harm.

Update on my situation. Fronts are wearing normally. Rear insides of both rotors are wearing normally, but the outside is still uneven (though better than before). I will be taking the rears apart this weekend to see if there's any abnormal wear. I have a rattling brake pad anyway that I need to fix! (Though I think the rattling brake pad is not related to the uneven outer brake wear).

I checked it out, bearings are OK!

The problem was the inside brake pad rattling against the rotor when the brakes were not applied. I've since re-seated the pad and re-lubed the sliding surfaces and the rattling problem has disappeared.
