97 Camry V6 XLE
So my FIL ask me to help change his brake because it is squealing. I took out the wheel and the pads on one side (not enough time to finish the other yet), and found the pads to have lots of material still on it. However, they are not wearing evenly. Instead of the common top / bottom uneven wear I've seen in the past on other car that points to top / bottom slope, this one has inner / outer uneven wear.
Something like this (not actual picture, but copied from others online), but much less severe
The pads from the same caliper are also not parallel when stacked together. If you look at how they align on the caliper (at the front of the hub), the orientation of the pads would look like a slight toe out.
The caliper bolts were very difficult to break loose (last break job was probably 6 years ago), the bottom sliding pin was sliding stiff but ok and in the rubber boot bushing, but the top pin has fallen outside the rubber boot and is not sliding freely.
I tried to break open the caliper bracket to check its condition, but the bolt (17mm I think) is so stuck that even with 2 feet of leverage I cannot break it loose.
What is worn out here? I'm going to replace the pins, bolts, and rubber boots just to be safe, and clean / lube the sliding surfaces and hardwares. Is it likely the caliper brackets and pistons are also worn out?
