i have an 03 wrx wagon. when releasing the e-brake, the daytime driving lights should come on and the e-brake light on dash should go out.. some times my day time driving lights don't come one and e-brake stays on. i am suspecting that the switch is getting stuck, but not sure where this switch may be, if there something else that could be causeing it, any of ya know what, where, and how to fix? thanks

 

You may find this strange, but check your brake fluid level. It is probably low.
Explanation-
The brake warning light is also connected to the level sensor in the reservoir, when the fluid gets too low the sensor turns on the light. Since this closes the circuit the same as if you pulled up the e-brake, the DRL controller will see the closure and thing the e-brake is up, and turn off the DRLs.
This should not happen, but is an oversight on Subaru's part as they should have added a diode to isolate the two circuits and prevent this, but they didn't.
Anyway if you do find your fluid to be low, don't just add some. Low fluid means one of two things- your brake pads are worn or there is a leak. Usually it's worn pads. Assuming it's the pads and there is no leak, you should replace the pads first before adding any fluid, since when the new pads are installed the level will come back up on its own once the pistons are retracted in the calipers. If you added more fluid beforehand it might then overflow.

 

lol, well don't i feel sheepish.. haa haa, changed front brake pads and rear is on order.. brake fluid lvl seemed to be on da low side, but was within lvl requirement before pad replacements, but was anough to be just enough to kick the e-brake light on.. cool beans, i know now and with that i can now know when it happens again, thanks!
