How often should brake fluid be flushed in Arizona?

Every 2 years or 30,000 miles is a solid guideline, but in the Phoenix area heat, fluid degrades faster. Brake fluid is hygroscopic — it absorbs moisture over time, which lowers its boiling point and can cause spongy brakes. David Jr. tests fluid condition during brake inspections.

What's the difference between a brake fluid flush and just topping it off?

Topping off just adds fresh fluid on top of old, contaminated fluid. A flush pushes all the old fluid out of every brake line, caliper, and the master cylinder, replacing it with clean fluid throughout. It's the only way to truly restore braking performance.

Can old brake fluid actually cause brake failure?

In extreme cases, yes. When fluid absorbs too much moisture, hard braking generates enough heat to boil the fluid, creating air bubbles in the lines. That's called vapor lock, and it makes your pedal go to the floor. Arizona's summer heat makes this more likely than in cooler climates.

Arizona’s intense summer heat, frequent dust exposure, and stop-and-go traffic on busy routes like Loop 101, Loop 202, and US-60 can accelerate brake fluid deterioration.
