My 2013 S60 RWD recently presented with stuck rear brake caliper symptoms, that e-brake feeling when driving at speed and sticking/almost jerking when accelerating at slow speeds. So much that I stopped driving it, and had it towed to service. Upon inspection, the service center found a parking brake caliper code and replaced those calipers at a cost of $1800. Unfortunately, this replacement did not solve the problem, and now they want to try new axles for $2300, and if that fails, they suggest it may be an issue with the drive unit.
However, I suspect that the service center may have overlooked some basic diagnostic procedures (like driving the car to see if a rotor heats up more than the others) and may have cost me unnecessary expenses. Around 11 months ago, I had to replace my parking brake pads after one of the pads fell off the metal backing. During that time, I drove the car for a bit without a parking brake caliper on one side, which threw a few parking brake codes along the way. I am concerned that the service center may have identified those old codes and charged me $1800 for replacing the calipers for no reason. Is there any way to verify this?
Furthermore, I am unsure if the service center is properly diagnosing the root cause of the issue, and I am not willing to spend $4k to find out I may need to replace the drive unit without proper confirmation that this is the problem. I would appreciate any advice on how to diagnose this issue beyond what the service center is trying @wk057 . It seems like they are focused on just throwing parts at the problem instead of proper diagnosis and repair techniques, which is great for cars under warranty, but not for me.
Thanks!
