DOT fluid will damage painted surfaces. If any fluid comes in contact with a painted surface (i.e. your frame) or printing on the brakes,
wipe it off immediately and clean it with isopropyl alcohol or water. Damage to painted and/or printed surfaces by DOT fluid is not
covered under warranty.
Inspect the caliper pistons for damage and replace the pistons if
necessary.
To install each piston use your gloved finger to apply a small
amount of DOT 5.1 fluid to the circumference of each piston. Install
the pistons into each half of the caliper body.
You can also use Avid DOT Grease or DOT 5.1 or 4 compatible
grease as a lubricant.
Spray isopropyl alcohol on the caliper halves and both of your
gloves, and wipe with a rag.
Remove the caliper o-ring from the outboard caliper half.
