RE: [alfa] Time for Brake MC

["kloliver" <kloli@xxxxxxxxxxx>]

Stefano;
Haven't seen the 24 mm MC but I swapped out the stock 22 mm MC in my GTV6
with a 23.1 (or 23.7, forget which one) to get less travel on the pedal.
Pedal effort went up only very slightly, but it was worth it for me (car
gets 80% track use and this worked perfectly for pedal positioning).

Re sourcing it - I bought my MC locally at Glynn Motorsports - I do not know
where else to get it.
ATE Part number is 03.2123-3402.3

Re fluid....would only use a DOT 3 or 4 and not mix DOT 5.  At this point,
recommend flushing system regardless of which you choose.

Hope this helps.

Cats,

Time for a new brake master cylinder for my Alfetta. My pedal
goes to the floor slowly. Pumping helps for a while, then back
down again. No external leaks. Am I right?

Questions about which to get. I have a set of GTV6 Brembo
calipers that will go on one day. I understand that the 22mm
is the better cylinder to use. I saw a website showing a 24mm
one. Is this a good upgrade for Brembo calipers, or overkill?
And does someone know what site that was? I thought is was
Spuell, but it doesn't seem to be there now.

My mechanic had mentioned he only uses DOT 5. I had a bottle
of DOT 3 and when the reservoir was very low a few months
ago, I filled up with it. Would this have anything to do with my
failure? Should I then purge the system when replacing and use
DOT 5?

Thanks,
Stefano
