Taking apart brake calipers.
I'm assuming that taking them apart is as simple as changing brakes. I spoke with someone and they said sometimes when you take them apart and put them back together, they can leak. Is this true? And what about it would case the leak, bad seals I'm guess? So is this something I can just order? I'm not sure what the part number or name would even be.
The reason I'm asking is because I'm debating on painting and clearing my calipers/mounting brackets. Don't wanna go powder coating because the car is a DD and I'm not trying to put that much money into it. I already have a sand blaster to clean them up nice before paintint too.
