I posted a thread some months ago regarding brakes, this is a related but not identical question.
I have just changed the wheels from summer to winter on my Aero auto estate. I noticed while I was doing it that the rear brake pads on the drivers side have worn down to their limit only a year since I replaced the discs and pads. Normally I would expect around 3 years/50k miles from a set. Both the inner and outer pads have worn evenly. I'm thinking therefore that the problem is a sticking piston.
Before I spend good time and money on the job, does this sound a reasonable diagnosis? In normal circumstances I'd say so, but I noticed the wheel was spinning freely before I touched anything (I was checking for free rotation in order to assess handbrake adjustment), so it just planted a seed of doubt in my mind.
The same problem exists to a lesser extent on the passenger side. The car has covered 217,000 miles with no attention to the brakes other than pad/disc replacement and appropriate copaslip attention to the bearing surfaces on the caliper holder and the guide pins.
Just as an aside, the rear suspension and wheels seem to attract significant road dust/mud etc, and the driver's side is the nearside (remembering I have lived in Austria for 5 years and drive a RHD car). I wondered if this is why the problem was greater on the one side?
