2005 GMC Brake Job

[K9Gunner]

I just finished up a front brake job on my 2005 Yukon. New pads and rotors. After I got everything back on I went to take it around the block and the brake light and TC light came on. The service brake system and the service stabilitrack messages came on. I have done many brake jobs on this vehicle and have never had this issue. Thanks in advance.

The place to start is back at the front brake area. You did the work and may have messed with/damaged a wire in that vicinity.

Check your speed sensor wiring connectors. One may have been disturbed.

Get the ABS codes scanned to narrow it down.

In addition to what has already been suggested, might double check your wheel bearing. If it’s on the edge of failing, all the messing with taking stuff off and putting it back together may have jostled something in the wheel bearing so the speed sensor isn’t reading correctly.

^^x3^^ Most likely inadvertently disconnected the speed sensing wire connector that sits on the top of truck's frame, above the hub. I inadvertently disconnected mine, while I was replacing a shock.

In addition to what's been mentioned:

Check your brake fluid level too. Low brake fluid will light up every light on the dash to try and get your attention

After it sitting all night last night all the lights have gone off and non of the messages are coming across. It’s weird but I’ll take it.

I would still go back in and check for a wire/connection problem, IMO.

I get nervous when problems “just go away” on their own. They have a nasty habit of coming back at the most inconvenient time and many times worse.
