That is the reason for Alex post.
The dust seal is more a humidity seal that isolates the brake fluid from the atmosphere.
Otherwise, the brake fluid sucks humidity (water) from the air.
That is bad for two main reasons:
1) Water corrodes internal metal parts, which damage seals.
2) Brake pads transfer a great deal of heat into the brake fluid. The water inside boils and becomes steam, which is compressible and acts like air in the lines.
