Today was a beautiful day to work on my truck. I've been pushing it off for a bit too long and finally found the time to get it done. My brake fluid was overdue for a flush, fluid was black like engine oil. It had a spongy pedal after I did a hydroboost flush last month when I changed out my steering box. Did a flush using 2 quarts and the pedal feel has greatly improved. The performance rotors and yellow stop pads were definitely a day and night difference, barely tap on the brake and it'll slow it down quicker than I expected. I preferred to stick with AC delco rotors and they are special duty type with slots. I didn't want to go with the drilled type because of cracks that will develop over time. My front rotors were shot from being overheated and the pads had plenty of life left but were glazed. Same issue with the rear but the pads were nearly gone.
