Subaru Forester Brake Discs: The Part That Pads Depend On
On the Subaru Forester, discs and pads don't wear independently — neglect one and the other degrades faster too, which is exactly why what starts as a routine pad change frequently turns into a disc replacement as well.

Subaru Forester Brake Discs: What They Do
Brake discs provide the surface the brake pads clamp against to slow the car, converting momentum into heat through friction. Larger, sportier trims of the Forester typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

A Genuinely Specific, Real Root Cause Worth Knowing Before Assuming Warping — Subaru Forester Brake Discs
If you're getting a vibration under braking on a car with otherwise healthy rotors and pads, this is genuinely worth knowing: rust or dirt trapped specifically between the wheel hub face and the rotor itself, rather than any issue with the rotor's own thickness, can prevent the rotor from spinning truly flush, causing a genuine wobble that feels just like warping. Cleaning the mating face of both the rotor and the wheel hub thoroughly has resolved this exact issue in documented cases on related Subaru models, worth trying before assuming new rotors are needed.
It's genuinely worth always replacing pads and rotors together and completing a proper bedding-in procedure, rather than reusing pads with new rotors to try to save money.
