my mom's brake line broke today on her 99 GMC suburban. she's been stressing about how much itll cost to fix because money's tight right now.
could anyone give me an estimate of how much it could cost for parts and approximate hours itll take? she drove it down to the mechanic we go to and he saw the fluid leaking out from under the car and said it should take about 3 hours but ive been reading online that it takes around an hour (but then again i know nothing about cars and our situation could be completely different)

for a normal repair for this kind of thing whats a rough estimate? the shop we go to charges around 75$ an hour in labor
