Applications:
Is this shim the right fit for your brake service? Yes—this 0.045" caliper shim is designed to correct caliper-to-support rail clearance when the measured gap exceeds .035". It restores alignment, helps prevent brake drag, and ensures even pad wear across the braking surface in heavy-duty fleet service.

IMPORTANT INSTALLATION NOTES:
✔ Measure caliper-to-support rail clearance with feeler gauges before shim selection.
✔ Install shim to return clearance to within OEM-specified limits (generally ≤ .035").
✔ Use only the required number of shims to correct fit—do not stack excessively.
✔ Do not allow the caliper to hang unsupported by brake hoses during service.
✔ Verify rotor-to-pad alignment after shim installation.
