I’m having a braking issue with my Honda City 2004. When the AC is turned on, braking becomes weak at low speeds, especially in slow traffic, and the car sometimes keeps creeping even with full pedal pressure. At higher speeds (30+ km/h), braking feels normal. Without AC, the brakes work perfectly. Could this be related to the brake booster, vacuum line, or something else?
