The right indicator may stop working when the brake pedal is pressed due to a wiring issue or a faulty electrical connection in the vehicle's lighting system. When the brake lights are activated, they may draw power from the same circuit that operates the turn signal, causing the indicator to malfunction. Additionally, some vehicles have a shared circuit for turn signals and brake lights, which can lead to this issue if there is a fault. It's advisable to check the vehicle's electrical system and fuses for any problems.
