I have Dexter 4 piston brakes on my '07. Here's my .02$.
Weak point, difficult bleeding if you do not incorporate inboard bleeding in the line somehow. AS turned the line right into the 3/8-24 to M10 adapter it is not the best for independent inboard bleeding. I rigged up a different hose and steel line combo to allow inboard bleeding. Works great. AS's latest hose also allows inboard bleeding.
Piston dust boots. If these split they can allow water in and the steel piston to cast iron caliper can start to rust and stick, causes dragging brake, heat and problems. Inspect couple times per year and replace if required.
The steel piston just moves in and out under pressure, the seal is in the caliper. I think it would take a lot of corrosion to make a caliper casting unusable, but corrosion on the steel piston ain't good that is the sealing surface.
I have replaced piston seals and dust boots, if you're mechanical, not a huge task but bleeding can make up for it.
Caliper to pad contact points, inspect for corrosion, clean up, apply a light film of caliper grease. Objective is to make sure pads don't hang up, drag and heat up.
IR temp gun is a great tool to monitor these for issues.
When done you have high performance 4 piston disc brakes.
