I notice the battery warning light and brake warning light come on the same time?

Hello,

The brake warning light can be illuminated due to low brake fluid, engaged parking brake, bad master cylinder or a defective proportioning valve.
Verify that the parking brake is in fully released position, brake fluid is at correct level.

Take a look at this article, it covers the typical issues:

The battery light comes on when the battery does not get charged properly by the alternator. Typically, it points to a bad alternator or a wiring issue from the alternator to the battery.
When the battery light gets triggered, a good first step would be to test the alternator output to the battery. It should be 13.6V to 15.2V with the engine running.
