How to Tell If Your Brake Fluid Has Gone Bad

Keeping your vehicle's brake at the consistency and level recommended allows for optimal function and extended life time of the braking system. Checking to make sure your brake fluid has not gone bad can save you time and money down the road.

Difficulty: Easy

Instructions

1. Locate the brake fluid reservoir, which should be clear plastic and labeled either on the reservoir or the reservoir cap. Wipe the cap with a rag before opening to avoid brushing debris, dust or other particles into the fluid.

2. Use a turkey baster or hydrometer to draw out some of the brake fluid for better visual inspection. Good brake fluid should be clear or slightly brown. It should closely resemble vegetable oil.

3. Notice if the fluid is dark brown or if there are particles in it. Over time, brake fluid absorbs dirt and moisture causing it to change and go bad. Brake fluid should be changed every 2 years or as needed, by consulting your vehicle maintenance guide.

4. Check with a professional mechanic if you are unsure about the life of your brake fluid. Take the vehicle to them and they will use the same methods of visual inspection, but with more skill and knowledge.

Tips & Warnings

• If adding brake fluid, handle it with care. Brake fluid can damage paint surfaces and harm your eyes. Do not use brake fluid more than a year old or if it has been left open, since excess moisture in the fluid can harm your braking system.
