Un-Even Brake Wear At The Rear Brakes??
 

Last night I installed new rear rotors and new semi-metalic pads. I noticed that the old drivers rear pads are more worn than the passenger side rear. Why is that??? If anyone knows why, please let me know. Thanks in advance.

Busy day yesterday, I did 2 oil changes, one oil change for my SVX and the other for my wifes 2000 Legacy Outback, plus the brake job I did on my SVX. LOL, I still have to the rear brakes on my wife's Outback! :D

This is a guess at what may be your problem. The brake balancer system equalises the force to the 4 hubs, and in theory ensures that your brakes do not lock up one wheel, or a pair of wheels.

What may be happening is the piston in the caliper that is wearing the pads less, this piston is sticking, possibly from dirt, possibly because it is ovaled. In which case, that brake would not be biting enough to give good retardation. At the same time, your ABS is compensating by not allowing the opposite [well worn pad] wheel to lock up.

So I think your problem lies with the one that is less worn. If you know how, then take off the caliper, get a recondition seal kit, take out and clean the piston and re-assemble. If you don't know how, bring it to a mechanic to have that caliper serviced.

Is the one that's worn more worn at an angle? This happened to mine as a result of a stuck guide pin.

Brake Pads
 

Thanks for the insight, but both break pads are worn evenly, just the left side worn more than the other.
