* Brake light fuse: This fuse protects the brake lights' circuit. A blown fuse here will prevent the brake lights from working, but it won't directly stop the brakes from functioning mechanically. You'd find this fuse in the fuse box (underhood and/or inside the car). Your owner's manual will show you the fuse box diagrams.
* ABS (Anti-lock Braking System) fuse/relay: If the ABS system is malfunctioning, it might have a dedicated fuse or relay. Again, check your owner's manual for the location and specifics. A blown ABS fuse will disable the ABS, but the brakes themselves will still work, although without ABS functionality.
* Other electrical components: Various other electrical components related to the braking system might have individual fuses. These could include brake pressure sensors or other parts of the electronic braking control system.
If you're experiencing brake problems, DO NOT attempt to troubleshoot the electrical system yourself. This is a critical safety issue. Take your vehicle to a qualified mechanic immediately. Driving with faulty brakes is extremely dangerous.
