New vehicles today cost many tens of thousands of dollars and are most likely one of the highest priced items you may ever purchase. Proper and regular maintenance of your vehicle is too often forgotten about shortly after a new vehicle purchase is made.
At Tierra Del Sol Automotive, our goal is to help you keep your vehicle performing like the day you purchased it. We help you keep track of your vehicle maintenance by sending you reminders and recommendations for servicing in accordance with your vehicle manufacturers recommended change intervals.
One often overlooked, yet very important service is to have your brake fluid tested and replaced every 30,000 miles. Like all other fluids in your vehicle, brake fluid degrades over time depending on your driving habits and the environments that your vehicle is driven in.
Tierra Del Sol Automotive offers the “BG Brake Service” – backed by the Lifetime BG Protection Plan®.
Many vehicle owners ensure they maintain their Lifetime BG Protection coverage by scheduling a BG Brake Service every 30,000 miles/50,000 km!
Other vehicle owners observe and report the brake fluid in their brake master cylinder reservoir appears clean and clear in color and elect to decline to service this vital fluid. While this appears to be valid at first glance, in reality, this is not necessarily the case.
Let’s explore why brake fluid that is clean and clear may still need to be replaced.
An Explanation of How the Brake System Functions
Unlike all the other fluids in your vehicle, brake fluid does not circulate out of the reservoir. This means that it does not leave the reservoir, go through the brake system, and then return to the reservoir.
Because the fluid does not cycle it is important to understand that the majority of the reservoir fluid most likely will never enter the critical components of the brake system such as the calipers and brake cylinders. Calipers and brake cylinders are the components located at the brake rotor or brake shoes that hold the brake fluid.
When the brake pedal is not being applied, the fluid that is closest to the calipers and brake cylinders is being cooled through these components by relative air passing over these components. In other words, the air over these components is responsible for cooling the fluid temperature.
Likewise, when the brake pedal is depressed, fluid pressure increases in these components and the brake pads or shoes are applied/pressed against the rotor or drums as a result. This action combined with the wheels rotating action causes heat buildup in the caliper or brake cylinder to several hundred degrees in mere seconds – resulting in constant heating and cooling of the brake fluid in that area of the brake lines.
In hard braking events, this fluid can potentially come to a boil due to high heat transfer. This can result in vapor creation, a by-product of boiling. You may suddenly notice a squishy or soft brake pedal or get the feeling the brakes feel abnormal or not as crisp as they felt in times past.
You may even look under the hood and notice the brake fluid level appears correct and the color normal. And you would likely be correct in your prognosis. But the fluid damage may not be evident in the reservoir. The boiled or burnt brake fluid remains within the calipers and brake cylinders and now also has air bubbles in it.
A quick refresher of elementary science class reminds us that fluids cannot be compressed! But air CAN! This is where the soft or squishy pedal feel comes from.
Brake systems can produce pressure up to 2000 pounds per square inch (psi). This pressure, along with extreme heat from the friction of braking, causes brake fluid to break down. This compromised brake fluid will boil at a lower temperature leaving air pockets and condensation in the brake system. Water in the brake system causes a myriad of problems such as brake deposits and varnish buildup.
