So my BRAKE illuminated display lamp is on on the dashboard. I am told it just needs to reset and it will not effect performance of the car or cause a problem. But why is it on and how would I "Reset" it. An answer would be appreciated, as I still have to move the car -SOON- and have work at 4 AM, so I would prefer to do so prior to that.
Okay, so first a quick backstory. My brake line developed a tiny pinhole leak in it, in the section between the master cylinder and where it splits. I had little choice given the lack of free time and the location other than to bring it to Pepboys, which was nearby.
Anyhow, I got it there, as it was like 1/4 mile and I didn't have to get it over 10 mph to do so. I removed the section (which is maybe three feet long, if you count all of the coils and bends) and put a plug in the master cylinder, to keep it from draining while the car was parked. I had to leave it there, because their technicians had all gone home already (Why the **** are you open then?) and I left the piece of brake line I removed as an example in the envelope with the service statement, explaining what needed to be replaced. I also left a note that said "MASTER CYLINDER CURRENTLY PLUGGED. DO NOT RUN" so they understood not to run it without removing that. Anyhow, two days later (today) I call them asking what the problem is (this is literally a thirty minute job tops) and why they have not called me. Well, it turns out they searched the entire brake lines on the car and could not find a leak. Well duh, because the part that was leaking was already removed by me, in their parking lot... So then they realized I needed that replaced, I explained that if it would not be done today I would not pay and will come send a tow truck for my car now, but they promised as such. Then they called later, because it needs a new master cylinder, because of how one side was plugged. So they ran the car and broke it. Great. Can't fight that, so I have to eat the loss on that too. $616 later, everything is just fine and dandy, except that now the BRAKE idiot light is on, which they said is normal and will just need to reset.
So...how do I deal with the fact that it is still on? Is this perhaps caused by a sensor that connects to where the brake line splitter piece is and perhaps illuminates to inform me that the parking brake is on? If that is the answer, I believe I may know why. If there is such a sensor there, their technicians may have reconnected the connector, causing the lamp to light. This is most likely because the previous owner disconnected said hypothetical sensor, as the light was possibly always on (my car has no emergency brake)
Two seconds of checking indicates that was the issue.
