Hey Scotty. I have a 2004 GMC Yukon XL Denali edition. It has about 275k miles on it. I bought it off my preacher at 244k miles, so I don't know the full life history of it. A couple of weekends ago I replaced the brake pads, rotors, and e-brake shoes on it (I ran out of time to flush the brake fluid, but the reservoir is full). I also rotated the tires while I was at it. Everything was fine the first week I drove it. I had the tires re-balanced the next weekend as there was a bit of a vibration, and that seemed to take care of that.
A couple of days ago I gunned it while pulling out in traffic and the brake light came on. As soon as I let off of it, the light went off. I stopped and checked the fluid and it was fine, so I didn't think much of it.
Today my wife was driving it to work and she said that an alarm went off inside and the dash read a couple of warnings: "SERVICE BRAKE SYSTEM" and also something about the "STABILITY SYSTEM DISABLED". She also said that the BRAKE Light and TRACTION CONTROL OFF light came on and stayed on. She pulled over and turned the car off, waited about a minute, and then restarted the car. Everything stayed the same with the lights, warnings and alarm being on. It drove fine, so she went on to work.
The ABS Light is not on, and my wife doesn't think it ever came on either. Any ideas what might be up?
Thanks in advance!
