How do you add Brake fluid on a 2000 Isuzu NPR?

To add brake fluid to a 2000 Isuzu NPR, first locate the brake fluid reservoir, which is typically near the back of the engine compartment. Remove the reservoir cap and check the fluid level; if it's low, use a funnel to carefully add the appropriate type of brake fluid (usually DOT 3 or DOT 4) until it reaches the "full" mark. After adding fluid, securely replace the cap and check for any leaks around the reservoir or brake lines. Always ensure you close the cap tightly and dispose of any spilled fluid properly, as it can damage paint and other surfaces.
