If both the RED brake light and the ABS light are coming on while you are driving the car, you either have an hydraulic failure or there is a problem with your ABS module that can potentially affect your regular service brakes.
The first thing to do would be to check the fluid level in your brake master cylinder. If it is low, you need to find out WHY. There is always a reason for the fluid level to be low. It is NOT SAFE to just add fluid without correcting the problem that caused the fluid level to be low.
If the fluid level is OK, then you must scan your antilock brake module for fault codes. The antilock brake module controls the antilock light and can affect the RED brake light as well. There are many different possible failures that can cause this. There is NO OTHER WAY to know why the antilock module has turned the light on. You can spin your wheels for days, replace a BUNCH of parts and never find the problem if you do not scan the module first.
It generally occurs while using the cruise control. The brake/abs lights come on and the
cruise drops out. You can reset the cruise but the brake/abs lights stay on.
Also, the odometer no longer records mileage while the lights are on.
I
found that, by pushing on the connector at the abs unit under the hood, the
problem will disappear and the lights will go out. The next time cruise is used,
the lights will reappear after a short time.
ABS LIGHT AND MODULE TROUBLESHOOTING:
Anti
lock brake system light comes up when there is issue with car brake systems. It
can be low brake fluid or faulty ABS fuse or its issue with brake system or assembly.
Your vehicles brake system needs inspection.
