Where you live changes how your brakes age. In hot, dry climates like the desert Southwest, brakes face a different set of stresses than in cold or coastal areas. Here is how to care for brakes in the heat.
Heat is the main enemy
High ambient temperatures mean brakes start hotter and have less margin before fade, especially on long grades or when towing; see why brakes get hot and brake fade. Sustained heat also ages brake fluid faster, lowering its boiling point over time.
Mind the brake fluid
Because heat accelerates fluid degradation, hot-climate drivers should keep to - or beat - the fluid change interval. Fresh fluid with a high boiling point is your best defense against heat fade. Consider a quality semi-metallic pad if you tow in the heat.
The upside: less rust
Dry desert air is actually kind to rotors - there is far less of the surface rust that plagues humid and salted regions; see rotor rust prevention and why one rotor rusts more. Brakes in dry climates often look clean for years.
Hot-climate tips
Downshift on long descents instead of riding the brakes, let them cool after hard use, and stay current on fluid. Choose pads rated for heat if you load the vehicle; see best pads for towing. Fit quality pads and hardware.
