Brake Fluid Reservoir Replacing Question

[Mike Robinson]

Hi all,

I am going to replace the rubber grommets that seal my brake fluid reservoir
this weekend.  I plan on pumping out the fluid in the reservoir, then
swapping the rubber seals.  Do I need to bleed the system?  I don't plan on
draining the entire system, just pulling the reservoir off and leaving the
fluid in the master cylinder and brake lines.  I don't see how air could get
in, but thought I may check first.

TIA
