I’m going to buy a new front calliper for my R8070 (di2) setup. 1st one had a shattered piston, second is not behaving well, may be the same issue. I bought it second hand on here, worked ok but never great so I want a fresh start.
Of all the flat mount shimano ones out there, what would you buy? I was thinking GRX400 for cost and also the fact it’s not a ceramic piston. Are there any that offer actual improvements, I’ve read 10% extra pad clearance on some, but is that only in combo with the new servo-wave levers?
Also, are the front 140/160 adapters all the same? If so I’ll buy a rear brake and re use the one I have.
