To add brake fluid to the clutch on a Volvo 850, first locate the clutch fluid reservoir, which is typically found near the brake fluid reservoir. Remove the cap and check the fluid level; if it's low, add the appropriate type of brake fluid (usually DOT 4) until it reaches the recommended level. Be careful not to spill any fluid on the paint or other surfaces, as brake fluid can cause damage. After adding fluid, securely close the cap and check for any leaks.
For a 1985 Volvo 740 Turbo, it is recommended to use DOT 3 brake fluid. Ensure that the brake fluid is of high quality and meets the specifications outlined in the owner's manual. It’s crucial to avoid mixing different types of brake fluids, as this can lead to brake system issues. Always check the fluid level and condition regularly to maintain optimal braking performance.

No, brake fluid should not be used in a hydraulic floor jack. Brake fluid is designed for braking systems and can damage the seals and components of a floor jack, leading to leaks and potential failure. Hydraulic jacks typically require specific hydraulic fluid, which is formulated to work safely and effectively with their internal mechanisms. Always check the manufacturer’s specifications for the appropriate fluid to use.
This is an easy one... Is the fluid green? if it is, it's coolant.. if not, its brake fluid.
A brake fluid leak in the system would do that. Check the brake fluid reservoir. If it is empty you are in need of brake work asap!
