I finally got around to changing all the brake pads on my 05 defender. (Not soon enough as one of the disks was scored from one pad being down to the metal )
The rears were ok, but the fronts were a bit of a pig, particularly getting the inboard pistons pushed back. I noticed that they were pitted and I had to work them in and out a few times to get them fully back. In the process, I popped one of the seals
Anyway, it's all back together and I'm deciding what to do. I need a new disk anyway, or the current one skimmed if it can be.
So, 6 years old and the pistons are pitted and need to be sorted. Do stainless pistons really last much longer? I ask because it's much-of-a-muchness buying 8 pistons, seal kits and time off the road vs just buying new calipers (with steel pistons obviously) if they are going to last about the same amount of time FFS
Your experiences please

If they are worth the money, could you recommend an online supplier.
