I just replaced a master cylinder a few months ago and
all was fine until today, when suddenly a spongey brake pedal.

It seems like a Master cylinder problem, more diagnosis when it stops
raining.
I don't have a lot of faith in the rebuilt brake cylinder since
when bench bleeding, only short strokes of the piston would be free
of air in two of the circuits.
I read on the board that some people stay away from rebuilt cylinders.

Is that right or are there people around that can rebuild the volvo M/C
and install stainless sleeves and do a good job?

My rebuilt M/C has a lifetime warranty, but maybe I should try for a refund if the quality is so bad?

comments?
