Symptoms
- Clicking sound each time the brake pedal is pressed or released
- May be more noticeable over bumps combined with braking
- No grinding or squealing along with it
Likely causes
- CommonWorn or missing anti-rattle clips on the brake padsThese small clips keep pads snug in the caliper bracket; when worn, pads shift slightly and click.
- CommonLoose caliper slide pins or boltsPins that aren't properly lubricated or torqued can allow small movement and clicking.
- PossibleWorn caliper bushingsLets the caliper move more than it should, causing a click under braking.
- Less commonLoose heat shield or splash guard near the brake assemblyCan rattle or click with the vibration from braking.
What to do
- Note exactly when the click happens, on pedal press, release, or both.
- Check if it's worse when going over bumps while braking versus smooth roads.
- Inspect the caliper area (through the wheel spokes) for any obviously loose or missing hardware.
- Have a mechanic inspect the pad clips, caliper slide pins, and bushings.
- Have any worn hardware replaced and slide pins re-greased with brake-specific lubricant.
- Have heat shields or splash guards re-secured if they're the source of the noise.

When to call a pro
See a mechanic if the clicking continues, since loose caliper hardware can lead to uneven pad wear if not addressed.
