Decided to get adventurous and take the bus for a drive. The rotors are caked in rust so I’ll just do the right thing and drive it around till they clean up. Well after about 20 minutes of tooling around the neighborhood I start to smell burning brakes. Guess which one of the front calipers is the problem?! It really sucks since these are the ones that were replaced 4 years ago by the previous owner. I was more worried about the rears.
