Black or Blue Boots?

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

  Standard Boot (see Note)
High Temp. Boot (see Pro/Con)
Color Black Blue
Material EPDM Silicon
Temp (F) 300 450
Cost Standard Adder
Installation Easy/Care free
Cautious/Avoid contacting brake fluid
 
  • Pro - Preferred by track drivers who constantly burnt out their OE boots under repeated high temperature braking.
  • Con - Must avoid contacting brake fluid, and/or using brake grease during installation, and if there is a brake fluid leak the boots will be attacked & ruptured, and must be replaced.

Do not use these, and NEVER lube blue dust boots with brake fluid or you will ruin the blue boots.

Note: Our standard boots although they look the same as OE or other aftermarket (black rubber), but they are strong and can resist to 300 deg F, much more durable than OE so in most cases that's all you need.

 

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