Silence the squeal from your Brembo 2-pot rears without compromising feel.
“The bite is there from the first stop, and it stays there.”
Cheap shims skip the elastomeric layer and rely on adhesive alone, which means they shift under heat and do nothing useful once the pad beds in. MSB's dual-material construction actually absorbs the harmonic frequencies that cause brake squeal, rather than just muffling them temporarily. At $26 for a full axle kit, it's the sensible fix before pulling the calipers apart looking for a problem that isn't there.
