Why do brakes get squeaky and stick even after you lubricate them?
Road grime and dust accumulate in previously lubricated brake parts, causing components to stick and pads to stop sliding well before the next scheduled service. This debris buildup makes it necessary to clean and re-apply lubricant between brake jobs even when the pads and rotors themselves are still in good condition.

“I just inspected my brakes due to a squealing noise (a pebble somehow got stuck in there) and noticed the brake pads were not sliding well even though I had lubricated them when I last did the brake job.”source ↗
“Does road grime make it so that the lubrication needs to be redone even though the pads/rotors/calipers are still good?”source ↗
“how important is the “silicone ceramic brake component lubricant”? The pads came with a small packet of it and I honestly just don’t want to take it back apart. If I do need to use it, where all should I apply it?”source ↗
