Performance Machine Anti-Rattle Spring - 125x4R

This is the Performance Machine Anti-Rattle Spring, part number 0052-1801-A. It's a small but important piece designed to keep your brake pads from rattling around in the caliper bracket. If you've ever heard a light knocking or rattling sound from your brakes, especially when going over bumps or when the brakes aren't applied, this spring might be the fix.

The spring works by applying a small amount of tension to the brake pads, holding them snugly in place within the caliper. This tension prevents the pads from vibrating or shifting, which is what causes that annoying rattle. It's a simple component, but it makes a noticeable difference in brake noise. Since it's a direct replacement part from Performance Machine, you can expect it to fit correctly into the designated spot in your caliper setup.
