Black or Blue Boots?

Dust boots not only can shield the braking heat, but prevent the brake debris, foreign particles (water, moisture, dirt & dust) from getting into the seal/piston chamber thus help to improve the caliper performance and extend the life of the caliper.

The blue boots:

Pros - Preferred by track drivers who constantly burn out their OE boots under repeated high temperature braking.

Cons - Must be careful to avoid contacting with brake fluid, or brake grease during installation or the boots will be attacked and raptured.

Note: Although our standard (black rubber) boots look the same as OE or other aftermarket (black rubber) dust boots, they are extremely durable and high temperate resistant up to 300 deg F, which in most are more than sufficiant even for track use.

CAUTION:

The dust boots shall only be installed "DRY", free from any sort of grease or oil regardless of boots materials, and NEVER use them especially for blue dust boots and must avid brake fluids, or you will ruin the blue boots.

Note: when the blue boots are attacked (ruptured), they look fresh blue and show no sign of being burnt by the heat at all.
