my service engine light and brake light are on. I had the codes read and read I needed a new computer so I bought and installed a new computer but the lights are still on. Does this mean I have more problems and do I need to have my electrical system worked on or at least looked at? What could this be?

Check for codes for the check engine light, check your brake master cylinder see if it is low on brake fluid you may have a leak. That is if it is the red brake light that is on, check your e brake make sure it isn't slightly engaged. If master cyl is low of brake fluid how does your brake pedal feel?
