My brake light keeps coming on. It will come on for a few min then go off any ideas why? And yes the brake is off

MysteryMachine said:i'll check that when i go back out. It does seem to do it most when you push on the brake. i was gonna check the fluid but haven't yet. Looked like christmas lights this morning going to work with the brake light and CEL flashing on and off
Something innocuous like WD40 can be used, along with a bore brush.MysteryMachine said:JT off topic. In that other thread you said about cleaning your egr valve what do you use to clean it or do you just scrape that crap off of the inside?
MysteryMachine said:I looked and the res. is a little low i'll put some in tomorrow and see what happens. Chris as i said before my pads are fine i had them off when i did all the suspension crap and they where like brand new. Its possible there was some ai i the line or something cause the res got low when i theft the lines off all that time. I'll fill it and see what happens and if it still comes on I'll make sure all my fittings are tight. Maybe the caliper I rebuilt didn't hold up LOL. Thats why I only did 1.
