Hi, I need some help. Me and my friend were working on the rear brakes in my 88 GTA and he ended up ripping the boot/seal inside the caliper. I had the car towed to the nearest garage thinking that I will only need to get a new caliper and then my brake pads installed, so no big deal. I left the car at the garage and called them the next day after they had checked it out. They said that I need to replace both calipers and the master cylinder. I understand getting both calipers replaced at the same time for sake of even wear and tear on them, but why the master cylinder? I asked why and the guy said that the broken caliper drained all the fluid from the master cylinder and broke it. That doesn't sound quite right to me, especially since very little fluid was lost while me and my friend were working on it and we only pumped the brakes 2-3 times afterwards to see if there was any pressure left...the car was not driven at all after we got started. My brakes weren't that bad to begin with either. I called another friend of mine who works for GM and he said that it sounds like the guy wants to replace the master cylinder because it's easier to do that rather than just fixing what is broke.
So my question is, does it sound like I need to replace the master cylinder? I only planned on spending about $100-200, and now I stand to pay $500 for what they want to do.
Any help/suggestions/advice is appreciated.
Thanks
