How to Check Brake Fluid

Maintaining Your Brake Fluid Level

The first thing you should do is clean the fluid reservoir before doing anything.

A car that runs well is useless if you can't stop when you need to. Caring for your car's braking system includes getting brake pads replaced, inspecting the brake rotors and ensuring you have enough clean brake fluid so the entire braking system functions correctly.

Most cars and trucks have see-through fluid reservoirs that allow you to see and check the brake fluid level without having to open the reservoir cap. You can find the brake fluid reservoir toward the back of the engine bay on the left side (or driver's side). It's usually up high for easy access. 

After you locate the fluid reservoir, look for markings along the side of the container. These makings show fluid level and indicate whether or not you need to add any additional fluid. You may need to wipe of some grime in order to see the mark clearly and read them.

Adding Brake Fluid

If you need to add more fluid to the reservoir, follow the steps below.

Before removing the fluid reservoir cap, wipe the area down thoroughly with a rag in case there is any grime. This will make the markings along the reservoir more visible. A car's braking system is sensitive. Any dirt or materials that find their way in can clog or degrade braking system components. So, it's always best to give it a thorough wipe down to avoid any future problems.

Remove the cap. Slowly, add break fluid until it rises to the desired level. Replace the reservoir and you're done. After a couple of days, you should recheck the level to see if you need to add more fluid.

One Thing To Remember:

DO NOT SHAKE a bottle of brake fluid before you add it to your vehicle. The bubbles created from the shaking action cause huge problems! And remember to replace your brake pads and rotors when needed as well to have a great all around braking system.
