When I drive my car my charging light and brake lights come on inside on the dashboard what's that problem
The charging light means your alternator is not putting enough voltage. Since you have to jump the car, I suspect your battery is low as well, since the alternator is not charging properly. Put a voltmeter across the battery leads and see what you have with the engine running. Is it 14V or higher? If not, new alternator. The brake light means you are low on fluid. Check the brake fluid resevior and add to the max. line. You have a leak since it's low, find where it is leaking and fix. You might have a rusted brake line or hose.
