Re: brake light on
There is a brake system balance valve that has a wire going to it. Typically near the mater cylinder where you put the fluid in. Remove this wire from the valve. ( You will also see 4 brake lines going in to this valve) If the light goes out, there was an imbalance in the front to rear brake system that tripped the light. You need to find the cause of this. This happens most often when someone replaces the front or rear brakes, and is pumping the brake pedal to get the pads or shoes seated onto the rotors or drums. Getting the light to go out is a matter of bleeding the brakes, during this process you will cause an imbalance in the opposite way that caused the light problem to start with. You need to find the cause of this light going on. Have the brakes inspected by a qualified garage telling them what happened Good Luck!

You needed to pay attention when the wheels started squealing several months ago. Pads are down to the rivets and grinding into the rotors.... time for a complete brake job... and a pricey one at that.
Check first the brake fluid level. This is found under the hood on the drivers side. Sometimes when the fluid gets low it will cause the light to blink. If the fluid is fine then have you Back brakes checked. If you have worn brakes this also can cause the light to blink or if you have drum brakes the wheel cylinder could be leaking fluid. You can look under the back of the vehicle on both sides of the insides of the rear tires and if you see alot of wet stuff on the inside of the rear wheels then you have a wheel cylinder that is leaking and could cause you to not have any rear brakes if it blows out. If you can do back brakes you can buy everything cheaper at any Advance or Autozone Store. I always buy new wheel cylinders instead of rebuilding them. Much cheaper. But do both rear wheels. Don't just do one. Hope this helps,
Are you sure the brake light (on the dash) is on because of the parking brake ?
Try this. Watch the brake light and at the same time set your parking brake. If the light seems to get slightly brighter then it isn't on due to the parking brake it is on for another reason.
If it does not get brighter then you need to look at the parking brake switch down by the parking brake as it may be grounded out causing the light to be on.
Be sure to check the brake fluid level. If it is low on brake fluid it will turn the light on also.
Your brake light is on because your brake fluid is probably low in the brake master cylinder. As the brakes wear, the fluid level drops proportionally. A switch in the brake master cyluinder measures the fluid level.
The //\\ light indicates you have a burnt out tail or brake lamp. All of the rear lamps are checked by a sensor, including the one in the rear window.
