Hey guys,

After a hand full of track days I have notice my Brembo caliper pistons are not holding up so well, same with the boots and seals.

I found a good option for seal replacements

But struggling to find replacement all metal pistons. It seems that there is a ceramic 'cap' on the end of the piston on the stock caliper, all the heat has cracked them.

Have any of you guys replaced your pistons with a more durable option?
The 1 series has replacements the same 38mm dia, but I need to confirm the piston depth... Has any one measured? Or does any one have access to a caliper piston to check the depth?

Thanks,
Nate
