Extraneous Creak - Toyota Celica, 2.0L, 1998

The last week, suddenly after the rain, the creaking of the front right brake began to strain me, moreover, while driving. On my part, the reaction was immediate. It was not necessary to remove the wheel, because the condition of the brake pads is visible through the disc. On this I calmed down, referring to the fact that perhaps the structure of the shoe itself is not ideal, something in the composition got caught, which grinds worse and rubs a little. Well, and perhaps because after a couple of days the sound on the move passed, there was a small one when braking. Not for long = (Yesterday everything resumed and began to strain again. Today, at 23 o'clock, I decided to take off the wheel and look in more detail. I was very surprised and at the same time miracles do not happen, there was a second rear block. So I have on the right the front wheel has one perfectly perfect block and the second dead block.
I also noticed that apparently when the brake discs were being drilled a year and a half ago, they apparently made a mistake and walked only one side, which I found out only today. Where to get one original half =)
