RC Strange Brake Pedal Feedback

I've got a strange issue with my 2017 Lexus RC with a gasoline engine. It's got about 77743 km on the clock. Recently, I've noticed some strange feedback from the brake pedal. I've checked the brake calipers visually, and they seem okay. I've also bled the brake system, but the problem persists. Could this be related to undervoltage in the vehicle affecting the hydraulic brakes? Any ideas?

Hey, I had a similar issue with my RC. It was the brake shoes. They were worn and causing weird feedback. How old are yours?

Thanks for the quick reply! I'm not sure when the brake shoes were last replaced, probably never. Is it possible that worn brake shoes would cause the strange pedal feedback I'm experiencing, even if the disc brakes themselves look okay?

Yep, definitely possible. The worn shoes can mess with the whole brake system's feel. Honestly, I'd take it to a trusted workshop to have the brake system checked over. It's worth the peace of mind.

Okay, thanks for the advice! I took it to a workshop, and you were right, the brake shoes were worn. Turns out undervoltage wasn't the issue at all. They replaced the brake shoes and pads, and the total repair cost was 240€. The brake pedal feels normal again. Appreciate the help!
