Brake master cylinder grommets.

[George Harris]

I have a leak in the brake system hydraulics which appears be from the
bottom of the reservoir between the reservoir and the master cylinder. I
believe there are 2 rubber donuts (grommets) that seal off the join and
allow some flexing of this joint.

Is it possible to remove the reservoir and replace the grommets and if
so, how much force and where is it applied?

The vehicle is an '87 5000CD TQ.

Cheers
George
