As brake pads wear down, they become thinner and must be pushed farther to rub against the rotor. The thinner the brake pads, the more brake fluid it takes to fill the calipers and squeeze the brake pads. Brake fluid is essential for the safety of you and your vehicle! Drop in for a free brake inspection at your nearest Tires Plus! Our technicians will check out your brake fluid and other essential brake system components, and make recommendations based on what they see — no strings attached!

Oily Puddle Under the Car If you notice a puddle of liquid forming beneath your car that is slightly oily to the touch, your brake system may be leaking.
Old Brake Pads As brake pads wear down, they become thinner and must be pushed farther to rub against the rotor. Up Next. Learn what this dash light could mean. Are you using your parking brake wrong? You should know that brakes will only function if you will be using the right brake fluid in the hydraulic system.
The brake fluid will affect the ease and safety of driving without having to use large amounts of pressure some distance before you need to stop. It will also help with light braking and will allow breaking to be an easier process all in all.
Checked the brake fluid regularly since it can absorb moisture. Alien liquid and excess moisture will deteriorate the brake fluid because of corrosion. Extra moisture might come from the atmosphere. The other liquid that will be drawn into the brake fluid will be affecting the boiling point, which is essential for the right braking. Take note that the boiling point of water is at degrees Celsius while a clean brake fluid will boil at degrees Celsius.
It is essential to avoid vaporization in the hydraulic system since it is compressible, which means that it will affect the stopping ability of the car. There will also be times when the fluid will contain some copper. It also prevents corrosion by lubricating movable parts and removing moisture within your braking system. Over time, brake fluid absorbs moisture through the caliper pistons, hoses, and connections. Brake fluid is hygroscopic so moisture is naturally pulled into the fluid through the atmosphere.
Too much moisture contamination causes the fluid to become vapor during hot braking cycles that negatively affects your braking ability. Signs that your brake fluid is contaminated include:. A brake fluid flush is an exchange of old, contaminated fluid for clean fluid.
The exchange occurs by bleeding out the old fluid with a power flush machine and adding new fluid. This process is important to preventative maintenance. But if the level is constantly dropping, you may have a leak, which you need to have repaired immediately.
If your brake fluid is leaking, the resulting loss of hydraulic pressure will have a significant impact on your ability to brake or slow your vehicle. This absorption process happens continuously, and the problem lies in how this moisture affects the fluidity — or viscosity — of the brake fluid. Consistent viscosity — even in extreme temperatures is essential for the brake fluid to work correctly, particularly if your car has traction and stability control and an anti-lock braking system ABS.
If the fluid is too thick or thin, the consequences could be devastating.
