Volkswagon passat hand break light stays on

Check your rear drum brakes a.s.a.p as they might have wheel cylinder leaks and your master brake cylinder will be low on brake fluid as the sensor for low level will leave the light on permenently.The rear wheel cylinders might not be visible but the leaking brake fluid usaully is but if not start at the master cylinder.Is the fluid level correct,does the brake pedal feel soft or spongy, is there fluid on the inside of the wheel/tyre.Rare for the handbrake switch to be faulty but may need lube but likely a brake leak.If unsure remove the rear wheels to be on the safe side of things.If all is okay the it will be a sensor on the master cylinder or the handbrake switch(but i doubt it).

Could be the switch on the hand brake mechanism out of adjustment. mcdevito75
