Drove with ebrake, now brake light/VSC/ABS

I somehow managed to drive about ten miles with my parking brake engaged today. I suspect strongly that something was already up with the parking brake, because I didn't notice any issues accelerating or turning. What I did notice was my dashboard lit up all at once - BRAKE, VSC, ABS. I stopped the car and poked around... I noticed an electrical hum from under the hood which I can't quantify, but it may be normal - I've never had cause to stick my head in there when the engine was on before. Brake fluid was normal.

Total ineffectiveness of the e-brake notwithstanding, brake performance seems completely normal. Braking is smooth, tight, and reliable, and does not affect the heading of the car.

I used OBD Fusion to read the codes, and got the following:

C0200 - Front Speed Sensor RH Circuit
C0205 - Front Speed Sensor LH Circuit
C1236 - Foreign Object is Attached on Tip of Front Speed Sensor LH
C1343 - Hydraulic System(RR)

I've booked time with my mechanic to have a look at the car, but that won't be until the 25th unfortunately. Does anybody have a sense of what's wrong, and if so, is it something I might be able to fix myself sooner?

 

I did a little more testing and found that if I put my car in Drive and floor the gas pedal, my brakes keep the car completely immobilized until I release the brakes 3/4th of the way or so. At that point the car starts to creep forward with a faint ticking/groaning sound coming from the brakes.

 

This was about nine miles of gentle rural driving between towns, and a mile of stop and go town driving. I really don't know how much heat the brake could have generated, as the car accelerated well and coasted as well as normal. On the other hand, the brake light probably doesn't lie, and I messed SOMETHING up.

I tried this a few times with no result. But I then tried one more time to clear the codes with my OBDII dongle, this time with the car in IGN-ON mode, and the lights disappeared and have yet to come back on. Maybe I'll get away with nothing worse than a handbrake cable tightening when I bring it into the shop next week...

 

Did this and didn't feel any warmth- the car seems to be running fine, with brake performance remaining good. I'm going to drive it as needed until my appointment, but I've used engine braking on a few occasions to help ease the strain on the brakes... it's probably doing more for my emotional state than the car, but every little bit helps!

 

Final update for anyone else with similar issues – after clearing the codes the lights never came back. Car drove fine until my mechanic could look at it, but it turned out I did wear down the brake pads a decent bit, and it cost $200 or so to replace them. The moral of the story is, a lack of brake burn odor doesn’t mean you didn’t burn them off!
