Do you have a scan tool capable of reading traction control codes?

 

[buicklucerne2006]

yes

 

[MelsRegal]

Can you share the codes with us so someone can maybe help you?

Properly bleeding the brakes & ABS along with checking the brake fluid level may be a solution based on your original post.

A professional scan would help to isolate what part and or area as it's not clear on how the parts installed already were decided upon as no code(s) or details provided.

Below is a link for a free Chilton Manual which will have instructions on how to do the brakes. If the master cylinder wasn't bench bleed prior to installing, air introduced in to the ABS or a scan tool used to cycle the ABS it would be advisable to read the instructions and proceed with corrections where needed.

I have had this happen several times. It was the front wheel bearings that were causing the faults to appear. Service Traction Control, Service Stabilitrac, and Service ABS all came on. Once the wheel bearings were replaced, the faults disappeared.

Yes that is another common problem but the OP had a brake related problem and the hub was not the issue for the warnings.
