• Laser-cut titanium shim set
• Must sit flat against the pad backing plate with no gapping
• Removes the need for factory rubberized shims
• Sized differently for sliding versus multi-piston calipers

Installation Details That Actually Matter

These titanium shims must sit completely flat without any gapping on the rear of the brake pad to work as intended. If your pad set came with other shims, such as the rubberized shims found on most stock pads, those must be removed before fitting titanium shims to avoid creating a pad over-thickness situation. The old shims can be pried off with a blunt screwdriver or similar tool to break the adhesive seal, and the pad backing should be lightly sanded afterward to remove any leftover glue or surface irregularities. For a component this critical, that level of specificity is exactly what you want to see.

Getting the Fit Right for Your Caliper Type

The new titanium shims must sit snugly against the pad backing plate with no debris trapped between them, since any gap there can create a long or spongy pedal feel. Shim sets for sliding calipers contain only two shims, and each one goes on the pad located next to the piston, while shim sets for multi-piston calipers include all four shims needed for the full axle set. Following these installation details precisely is what separates a shim that actually protects your calipers from one that just adds an air gap in the wrong place. That's real, testable information, not just marketing language.
