After converting drum brakes to disc brakes, residual brake pressure may cause rear rotor drag and overheating, but the user cannot identify where the residual pressure valve is located or how to resolve it.
No clear guidance exists in OEM parts documentation or online forums that reliably explains where residual pressure valves are located in this specific vehicle model after a brake conversion.
