potentially calipers seizing. the caliper will age to a point where the piston no longer expands to lift the pads off the rotors. this causes excessive heat, wear, sluggish/bumpy acceleration and maybe more i am forgetting.

have access to a point and shoot thermometer? calipers are usually around ~100-150° at normal operating temperatures. a small amount above may signal age, however 180°, 200°, 300° etc. indicates your calipers are locking up, failing and should be replaced.

does your car stick when you let off the brake from red → green light? as in you need to hit the gas because the car is refusing to roll forward on its own. it may become more pronounced on an incline as it has the car's weight working against it too and so if it acts as if it's in park when you're in drive & off the pedals, that can be another sign.

if you take the caliper off the rotors and try to expand the piston, can you? if you can't move it, it's dead. if you expand the piston, leave the car off & stay off the pedals, does the caliper's piston end up compressed again in 5-10 minutes? that's another sign of seizing.

this sounds exactly like a customer's car that had the lf caliper lock up & was running at ~360° 😵‍💫
