parking brake question
hey guys, i have a question about the e-brake on am 02 wrx. whenever i drive the e-brake light seems to come on and the daytime running lights shut off and on. this has just started to happen and i get kind of irritated seeing the light come on and off while my headlights are doing the same thing. anyone have any info of suggestions? thanks a lot.

Your brake fluid is probably low, and is tripping the sensor float in the reservoir and turning on the brake light. When this happens, the DRL module sees the switch closure and thinks you pulled the e-brake so it turns off the DRLs. This is a design oversight on Subaru's part, they should have added a diode to isolate these circuits to prevent this from happening.
Anyway the solution is to check your brake fluid. If you do find it to be low, don't just add more. The usual reason for low fluid is worn pads, so check and replace them first, doing so should bring the fluid back up to the proper level if there are no leaks in the system. If you add more fluid before changing the pads, the reservoir can then overflow when the pads are replaced and the pistons retracted.
