To add brake fluid to a 1991 Isuzu Trooper, locate the brake fluid reservoir, which is typically situated near the back of the engine bay, close to the driver's side. The reservoir is usually a translucent plastic container with a cap labeled for brake fluid. Remove the cap and pour in the appropriate type of brake fluid (usually DOT 3 or DOT 4), ensuring not to overfill. After adding the fluid, securely replace the cap and check for any leaks.

To add brake fluid to a Ford E-150, locate the brake fluid reservoir, which is typically found near the back of the engine compartment, on the driver's side. The reservoir is usually a small, transparent container with a cap labeled "Brake Fluid." Ensure the vehicle is on a level surface, remove the cap, and add the appropriate type of brake fluid (usually DOT 3 or DOT 4) until it reaches the "Full" mark. Always check for any leaks and ensure the cap is securely replaced after adding fluid.
The brake fluid master-cylinder cap usually specifies the correct type brake fluid for the vehicle. It is embossed in the warning statement on the cap. If the vehicle's master=cylinder cap does not have a warning statement there is usually a label near the cap that details the brake fluid information. The information is also typically in the owners manual under fluids and maintenance. I believe this vehicle should use DOT 3 brake fluid.
