Sounds silly but it is easy to get confused on what each light is telling us. Maybe check the chassis manual to see FOR SURE what each light means. Do you have two different lights or does your model have one combined light to tell you to check brakes and it can be either park brake on or the actual brake system.
The question is if you have two different problems that came up at the same time or is it one light. We feel like we should only have one problem show at at a time but we're not always lucky!
So if you have two problems, the easier one may be the park brake light on. If you can find room to get down and look along the park brake mechanism, there may be a switch with some form of connection to the lever, ect., that moves as we set the brake. Often about the only thing connected to the park brake gizmos with wires? Usually kind a of funky looking switch with an arm or some way to "feel" when the pedal is up or down? If it get loose, the switch doesn't tell the light to turn off!
Maybe it got loose or the wires pulled off?
Maybe like one of these?
Depending on model, etc. the ABS light may be more involved with brake fluid levels as a first thought.
Newer and older vary but check the brake fluid levels as a first thought. There are likely to be two different sections, one for front and one for back brakes. This is a safety thing so that one brake line failure at one wheel doesn't kill all four brakes, just front or back.
If fluid is low in one side, that shows leaking to front or rear, so don't just top off and go but try to look further and find what and why the fluid may be low.
