After discovering one of my brake lines was broke i decided to replace all four and also do some maintenance work on the calipers since one of them was in rough shape, so when i took the pistons out i noticed they had some pitting in them, one has a lot the other three are pretty small pits but i don't know if i have to replace all four or just the worst one i hope someone can steer me in the right direction. My plan is to upgrade eventually to the big reds or brembo but right now budget is really tight and i would like to save as much as i can towards the upgrade.
I'm ordering rebuild kits for all four calipers but I'm lost with the pistons, if i have to replace one do i have to replace all four or just that one?
is there a way to fix them? welding or brazing or something?
i was looking at the DuroAno S-Caliper Piston sold here what do you guys think about these?
this is how the pistons look like
thanks in advance
best regards
