Default uneven brake wear

While doing my snow tire swap today, I checked all 4 sides of my brake pads and noticed one of the rear side wears out more than the other side.

Anyone know why and remedy?

Grease your caliper sliders.

I just had that issue on my 08 wrx, caliper was sticking on one of the rear wheels, had to have it replaced, one pad looked brand new, the other one was more than half worn down.

Default Similar brake problems

I have a 1995 Legacy wagon and have a similar problem with my rear brakes as detailed above. On the passenger (right) side, the rear brakes wear the inner pad at an angle and the outer pad barely touches the rotor. I greased the guide pins, replaced the pads, and saw no difference.

Okay, I figured that the caliper had a sticking piston, or there was looseness in the caliper that was causing it to shift and allow the pad to be worn unevenly. So I replaced the caliper, rotor and pads, lubricated the guide pins (including the lower bolt that's used to hold the pad carrier to the caliper) and still have exactly the same wear issue: The inner pad wears unevenly and the outer pad barely touches the rotor.

Today, it is blazing hot and humid (around 100F) and the right-rear brakes just locked up when I stopped at a stop light. I limped to a nearby parking lot and let the car cool for a while - the right-rear brakes were smoking badly. After an hour or so, the car drove perfectly normally, as if there was no problem. I took the right-rear wheel off and confirmed that the inner pad is worn at an angle and the outer pad is barely touching the rotor. (There is rust on part of the outside of the rotor, so I know the pad is not making good contact.)

Any thoughts on this? My 1995 Subaru has a bazillion miles on it (232k+), so I'm not going to sink a lot of money into it. But if there's something obvious, I'd like to know. The car runs, drives, stops and works fine, otherwise.

Thanks in advance for any helps!

I think that I finally figured out what caused my 1995 Legacy wagon's uneven rear brake wear. It was the hill-holder mechanism. I had noticed for years that the car didn't move completely smoothly, and knew this meant that the brakes were dragging somewhere. After the car got stuck (described above) and one more time where I needed a tow, I did some checking and read that the hill-holder mechanism can stick. I'm now sure that's what happened to me.

I completely disconnected the cables for the hill-holder and the car now has no drag. Of course, it's a little trickier starting up on a hill with its manual transmission, but I've been doing that for years in a variety of other cars. I don't miss the hill-holder -- especially since it twice locked up, caused problems and required a tow.

I love the hill holder here in downtown seattle. Love love love it.

Of course there is an adjustment that can be played with too. But if yours was "sticky," you do what you gotta do.

This seems to be very common on a lot of subaru slider type calipers. Before I swapped out to the bigger brakes I had a stuck rear caliper as well. It must be a subaru thing as my nissan's old brakes were very similar in design but never had this issue.

Just my 2 cents.

Did my '02 brakes this past spring all around. My caliper sliders needed regreased. They functioned, but were hard to move. This is a quick fix you can do yourself with just taking the wheel off.

If that doesn't work, then it may be the actual caliper pistons themselves, which require either a rebuild or replacement.

Have had 2 frozen calipers on my 04 wrx. I had rebuilds from NAPA. Luckily they were under warranty and replaced them.

What do you recommend for lubing the sliders?

brake grease. They usually have little packets of it by the counter at most auto parts places like Autozone.
