Handbreak light will not go.

Red light indicates hand brake on, hyraulic failure in the system or abs issue.

Is the yellow abs light on as well.

Roy

Ok, you need to see what is going on with the abs. Have the code pulled and get back to us with the number.

By the way, I forgot to tell you another reason is the low fluid level switch in the master.

Roy

Dont assume anything with the abs till you know the code.

The float moves up and down and when is down low enough, it will turn on the light.

You still need to address the abs before the light will go out.

Roy

New brakes have no effect on the light unless there was damage done to one of the sensors during the job.

I cant answer why as I did not do the job, someone else did it.

No matter what, you need the code pulled so we can further help you.

Check the other items as well.

Roy

Check the brake fluid level in master cylinder first. Unplug the fluid level seneor to test if necessary.
