Hey guys. This is my first post here, and I really need y'alls help. I have a 2003 Mustang
Convertible (non-GT), and I took it in for a tire rotation and 100k flush last week. However, when I picked her up from the lot, there was a weird grinding sound around my front left tire. I brought her back, and the mechanic is saying it's a locked caliper issue with the front driver tire, and it's affecting both the brake and the suspension. He says I need a new brake, a new suspension, and a new caliper, and is requesting 3k to fix ($500 more than the car's even worth). I think they screwed something up because she wasn't having any issues before I brought her in for maintenance, but they provided a tire rotation and 100k flush, and now it's grinding anytime I brake or decelerate at less than 30 mph.
I love this car, and I'd rather not part with it, but I want to know if what the mechanic's saying is reasonable, or if I should sell her and move on. Any help would be appreciated. Thanks y'all!
