Cold Weather causing the Left Rear Brake light to come on
When it is cold outside, the left, rear brake light will come on at some point during the night on my 2004 Audi A4 Quattro. This has killed the battery once, as it happens while I am asleep. I have checked the appropriate fuze, and all the rear lights still work.

Re: Cold Weather causing the Left Rear Brake light to...
That's the most interesting problem I've heard all week. I'm pretty sure this has to be problem in the switch that operates the light. Are you positive it's the brake light and not just the tail light? Tail light switch is part of the headlight switch. If you're sure it's the brake light, replace the switch under the brake pedal arm, under your dash. I think this is the problem because unless the circuit is engaged at these switches, it's impossible to activate them from anywhere else. Brake switch is easy. You can do it your self. Headlight switch usually involves removing the steering wheel and is kind of a pain but not too overwhelming.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Assuming that the Tires for both Left and Right are:
1. Equal Sizes.
2. Both Properly Inflated - this is a common problem.
3. Have equal wear on them. Example: If the Left Tire is balding on the outside and the Right Tire is balding on the inside, this too is definite sign of an aligment issue; and will cause unequal braking.
Pulling left (or right) during a hard brake might actual mean your Wheel Alignment is way off. When you get one, get a 4-wheel and not just a 2-wheel alignment.
Also: you thought the right thing, but the Left Caliper or Left Brake Hose might also be bad (sticking) causing the left side to brake "harder" then the right side.
You can also Bleed the entire System (all four wheels) starting at the Right Rear, then Left Rear, then Front Right, followed by the Left Front.

As you apply your car brakes, your brake pads/shoes wear against the brake rotors/drums. Rear brakes usually have brake drums. As your brake shoe linings wear (as would be the case for your car), the brake linings from the brake shoes have worn down to metal and they wear into the metal of your brake drums. After you park the car at night, the natural moisture in the air facilitates an oxidation (rusting) process along your brake drums. When you get in your car and take off in the morning, you have a light layer of rust that gets scraped off by your worn brake shoes. This is what is causing that annoying noise you hear in the morning (or after the car has been parked for hours). Simply put, you need a rear brake job. They will also check your front brakes and can let you know how much life you have left up front. If you continue to drive around like this, you'll end up ruining your rear brake drums and this will quickly become more expensive. When you have a rear brake drum job completed, they will likely "turn" your rear brake drums - which means they will put the drums on a mechanical lathe that will scrape any uneven surface into one congruous even surface.
Hi, No model of vehicle or year both would help!
sounds like you need to ensure the back light is never left on before leaving the vehicle. you need to check the tension on the brake light switch or replace the brake light switch normally under the car without full details hard to state where brake switch is located. Please leave me feedback, Malcolm Campbell.
take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,
