The brake fluid reservoir in a 1993 Jeep Cherokee is typically located
under the hood, near the firewall, and often close to the master cylinder. It's usually a small, clear or translucent plastic container with a cap. Look for a cap labeled "Brake Fluid" or with a brake system symbol (often a circle with a line through it, representing a brake caliper).
Because there's some variation between models, you'll likely need to consult your owner's manual or a diagram specific to your 1993 Jeep Cherokee (XJ) model for the precise location. A quick online search with the terms "1993 Jeep Cherokee brake fluid reservoir location" and an image search should provide additional visual confirmation.
