Purchased a 02 SVT Focus about 10 months ago, I love the car. On my way home from work on friday evening, I started to hear a really loud grinding noise in the rear right of the car. I stopped and gave it a visual inspection, but it was dark. I decided to keep driving until I could got home and inspected it in daylight. Drove off and came to red light, hit my brakes and my pedal went mushy. I managed to drive home using the E-brake and downshifting. Later on the next day I found this problem, please help me identify the broken part.
