I had overheating and a burning smell from the passenger side brakes two weeks ago, I got the local garage to check and they said it needed pads and discs and it didn't look like anything was seized. It's a lot better but still gets hotter on the passenger side, I took it back and they thought it might be the flexi hose, but when they inspected that they said it was ok and it needs a new caliper.

Does that sound reasonable? I wish that they had checked it properly at first and I would have thought they would have been able to see that the caliper was seized.
