Greetings all -
Alternative seals for 105 GTV master cylinder?
I'm refurbishing the brake master cylinder on the 105 ('71 Euro GTV,
standing pedals, underfloor tandem MC, dual remote boosters, all that
carry-on). The MC is a Bonaldi 7/8 inch unit, and like a lot of old Italian
ones it uses oval hydraulic seals instead of the usual cup seals with a lip
that most other MCs seem to use.
I've heard form vintage brake specialists etc that these oval seals often
don't work as well as normal cup seals, so I wonder if there's any reason
not to try cup seals in the Bonaldi MC? Or in the Benditalia GTV underfloor
MC that I've got as a spare, that also uses oval seals. Certainly I've never
been impressed by the GTV's pedal feel so I'm keen to find a way to improve
it.
Has anyone in the group ever tried this use of cup seals, or are there any
comments on this idea?
I got the idea from this website:

It sounds good! It is however on a slightly different Bonaldi cylinder from
the GTV one I'm working on.
Thanks all,
