FAQ:

Q: How do you test brake fluid?

A: To check your brake fluid, do the following: Clean the top of the reservoir carefully. Open the top of your brake fluid reservoir. Look to see where the fluid level lies; make sure that the brake fluid level is within half an inch or so of the cap. Check the color of your brake fluid.

Q: Why is test brake fluid?

A: The cheap electronic brake fluid testers measure moisture content in the fluid because the brake fluid absorbs moisture from the air. Enough moisture in the fluid can cause the brakes to feel spongy, they won’t work as well, and can boil the fluid quicker during heavier use.

Q: Why does brake fluid need to be replaced?

A: If you have replaced the pads/shoes and the calipers or wheel cylinders suddenly began leaking, that’s a signal not only that it’s time to replace the leaky parts but also to replace the brake fluid. Brake fluid is hydrophilic, meaning that it’s formulated to absorb moisture.

Q: What is the composition of brake fluid?

A: Brake fluid composition. Brake fluids usually contain up to 5% of additives. Corrosion inhibitors are added to protect the brake system metals from corrosion and antioxidants are needed to reduce the oxidative decomposition of glycol ethers polyglycols and to retard the formation of acidic decomposition products and resins. These two inhibitors’…
