More Fun... Brake Light
Ok, so a couple weeks ago I noticed that the brake pedal was getting softer and stopping power was diminishing. A few days later, the brake light started coming on and I knew I would have to get to work on it soon.
So a couple days ago, I got the oem ceramic pad and disc set and installed them a few mins ago.
Now before, the front calipers had been doing that 'creaking' sound thing, which mysteriously disappeared... Come to find out, one pin on each caliper was completely frozen in place with rust.
I tore the calipers down, resurfaced the pins and lubed them all the way to heaven and back. Put on the new rotors and pads, and alero stops on a dime again now.
But the brake light CAME BACK ON AGAIN. And I'm not talking about the abs light because of the sensors, I'm talking about the reg brake light.
???

lol
look at your brake fluid level, you likely have a caliper leak. brake fluid rusts ferrous materials, so surprise at your caliper pin rust. check your lines too

Thats what I thought of when you mentioned that, the sending unit. But I think its bizarre that it happened in coincidence with the brake performance going bad, so I'm thinking it has to be related.

the sensor or "sending unit" as you like to call that plug in the brake fluid reservoir
if it's not low, if you don't have leaks, and your braking system functions flawlessly as you say, then the sensor MUST be bad.

you might need to invest in some crossed drilled brake lines.
j/k
I'd also say the sensor could be bad... so I second Ion's assumption.

If the vehicle speed is greater than 5 km/h (3.1 mph) with the park brake engaged, the BCM sends a class 2 message to the radio in order to activate an audible warning.
The electronic brake control module (EBCM) detects a low brake fluid condition (signal circuit is low). The IPC receives a class 2 message from the EBCM requesting illumination. The IPC sends a class 2 message to the BCM indicating that the brake indicator is illuminated due to a brake malfunction. The BCM sends a class 2 message to the radio in order to activate an audible warning.
The EBCM detects a malfunction in the braking system. The IPC receives a class 2 message from the EBCM requesting illumination. The IPC sends a class 2 message to the BCM indicating that the brake indicator is illuminated due to a brake malfunction. The BCM sends a class 2 message to the radio in order to activate an audible warning.
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
The IPC detects a loss of class 2 communications with the EBCM.

Now I'm not certain about the Aleros, but I know some GM vehicles are infamous about the lights not going out after the problem is fixed... reason: The computer must be reset... Now his can be done by the dealer, with some hand held OBD II scanners, and in some cases disconnecting the battery and reconnect after 30-45 seconds.
I don't know if that'll help as it may still yet be another problem, but it's worth a shot.
