Front left brake was acting up pulling and not want to stop at times, so they replaced the Censor and cleaned the area, changed
a wire, check the fuses and it still is not working properly and the lights still come on.

 

What year is your Equinox?

Exactly which warning lights/messages do you see?

 

It is a 2005

 

The Abs light and the light up in the right top

 

Based on this I'm thinking the brake hose is acting like a check valve and not allowing the caliper to release. This could cause that wheel to lock up under certain conditions which would cause the ABS to want to engage when it is not really necessary. The ABS computer may interpret this as a sensor fault.

It is common for the metal bracket attached to the hose to rust which pinches the hose. I'd recommend replacing both front brake hoses because of how common this issue is with the 2005-2006 Equinox and the 2002-2007 Saturn Vue which uses the same brake hoses. The 2007-2009 Equinox uses different brake hoses that seem to be less susceptible to this issue.
