Already took of pedal, don’t know how to check if it’s working

Have disconnected the battery over night see if anything changes when I put it back on

Also checked all my fluids and everything was good .

Idk what to do don’t have the funds to take it to shop if someone can please advise me what steps or parts I may need to fix this issue.
