Do I actually need to replace both front calipers? Since he's taken both off, the guy tells me that the fluid has leaked, and thus the calipers canNoT be repaired, but need to be replaced. When I look at these heavy metal substantial components, it's hard to believe they can't be repaired. What's the deal, please? Please give me info/links/etc on this brake-fixing business. And if I do have to replace both calipers, where's the best price for them? I've already replaced the master cylinder ~ yeah. But right now, it feels like there's no end in sight.
