Stoptech ST-40 kit failures?

[Pranav]

When I got a used set from Matt he provided fresh seals/boots, so I immediately re sealed them

I would invest in a spare bridge line and ditch the bleeder screws for the two piece wilwood units so you don't wear out the screw holes in the calipers over time.

I think doing fresh seals and inspecting your pistons and bores is a good move but other than the bridge line, seals, and bleed screws, I don't imagine anything else being a long term issue on the calipers themselves

I made the investment in a spare hat and hardware, and keep some old rotor rings in case those break/crack or something.

Zeckhausen is a great source for the stop tech parts, he will get you set up
