Every vehicle owner knows that routine maintenance is the best way to ensure longevity and reliability for their vehicle. That goes for high-quality models like the Acura RDX, ILX, TLX, MDX, and RLX, and especially for high-performance vehicles like the Acura NSX. Likely, you know all about when to change your engine oil. But do you know when your Acura brake fluid change need to be done?
Why does it need to be changed at all, and what does brake fluid do anyway? Here’s some helpful info to help you out.
The Function Brake Fluid Performs
Your brake system operates on hydraulic pressure. Brake fluid fills the system from the master cylinder reservoir to the brake calipers at the wheels. Every time you press the brake pedal, fluid in the brake lines is forced toward to the wheels, squeezing the brake pads against the brake rotors. On the odd vehicle with drum brakes, wheel cylinders press the brake shoes against the brake drum inner surface.
Why Change the Brake Fluid?
It’s a chemistry lesson you need to learn. Brake fluid is known as ‘hygroscopic’. In lay terms, it means it’s formulated to absorb moisture. Water molecules bind to the fluid to prevent corrosion inside the braking system.
The more moisture the fluid absorbs, the lower its boiling point. When brake fluid boils, your Acura’s brakes are much less responsive when you press the pedal. Contaminated brake fluid can cause an accident or force premature brake repairs.
How Often Should This Service Be Done?
A good rule of thumb is to have a brake fluid check every oil change interval. The technician can verify that it’s still in good condition, or recommend if a flush and fill is necessary.
Actual fluid service intervals depend on your driving situation. For some drivers, it may be necessary every 12 to 18 months while others are longer. At a minimum, brake fluid should be changed every three years according to your Acura maintenance schedule.
At Acura Overland Park, a factory-trained technician will drain old fluid from the bleeder screws at each caliper. Fluid in the complete braking system, from the brake fluid reservoir to each caliper, is drained and replaced by fresh fluid. Not sure how your brake fluid is doing?
