Brake pad warning light illuminated!
Hello everyone.
I recently have been getting a brake pad warning light to come on every now and then on my '84. And I know that my rear brakepads might be the culprit.
I just want to make sure it's still OK to drive for a little bit without having to change the pads. Say...2 weeks? I looked at the pad and it has about 6MM left on it.
Please advice. I will be ordering the pads (sensors too?), but it'll take time to come in by mail, so I just want to make sure I'm not being stupid by driving the car around (daily driver).
I'm not too familiar with break pads and how thin it can tolerate, so I'm just playing it on the safe side.
Thanks ahead of time for responses.

The sensors are there to warn you when to be careful - before the pads are worn out, once you hear the metal scraping sound it's to late...
You should have about 10% left of the pads.

The brake pad sensor is designed in a way that if it gets scraped by the rotor (when the pads are thin), a wire in the sensor opens and the light comes on. If your light is coming on now and then, I would check the sensor grounds at each wheel. My car got jolted on a speed bump and my pad light came on. I know my brake pads are fine, so I cleaned the ground points at each wheel and the light is out as is should be. You can see the condition on the sensors by inspecting them at each caliper. If they are not scraped open, they should be fine. You can put an ohm meter accross the sensor wires to check that the loop is closed.

Change the pads and sensors as soon as you get the new ones, but you could safely drive for several thousand miles with the worn ones. There is a big safety factor built in.
