Belle Tire Indicated brake calipers and pads required instead of just pads, indicated pressure sensor was leaking when it wasn't Madison Heights, Michigan

Went to Belle tire last spring for new tires and had them look at my brakes because of squealing noise.  Told me that I required two rear brake calipers and pads.  Brought it to dealership and they indicated that I only required two new pads.  There was nothing wrong with calipers.

I temporarily patched nail hole in front tire.  Held air with no leaks for over 2 months.  Found another nail in rear tire so I brought vehicle into Belle Tire to get both tires properly patched for free as per their warranty.  They called me in and said that they located the nail in the back tire, but they could find the temporary patch I put in the front tire.  But told me that they did however discover a leak around the tire pressure sensor.  I asked them to show me.  They put soap solution around sensor but nothing happened.  They said never mind, and then proceeded to take tire off and repair both nail holes.

On my way home I could smell a distinct odor of leaking radiator fluid.  Found that one of my hoses had been damaged from below the vehicle.
