III Pro PEERAGE 4 brakes - piccola clone

[Tijoe]

Does anyone have a link to a IIIPro 4-piston caliper rebuild kit?  One of my rear caliper's pistons has started leaking and sucking in air.   (All things considered, not many hours of usage on these calipers.)

I bought a set a couple of weeks ago and only got to fit them on Saturday. I can't use the bike they're on right now until I get tyres but the brakes were a doddle to set up. I did have the trim the front hose but the rear was only just long enough for my bike. The brakes arrive pre-bled and I didn't realise they had a shorter hose from the lever that the remaining hose connects to. I like that a lot and bleeding the rear brake was just the same as shimano. Brakes feel nice but there is a lot of pull on the lever to require the pistons to move. I'll have to update here once I get riding them. They look great and weighed 400g with pads for front and rear once front hose was trimmed about 150mm.

Any updates yet? How do they perform in terms of braking power if you compare them to XTR or Level brakes?

The iiiPro post and flat mount brakes share similar components like bleed screw. I'm curious if I could use the post mount brakes on a gravel build for more stopping power.

I do.
I just installed few days ago the XG4 / IIIPRO flat mount kit with GRX shifters in my gravel bike.
Quite annoing bleeding but now it works.
Need to brake in the pads but "i got the power" now comprared to Apex
