Titanium Front Caliper Spacer

This is a common component in titanium alloy screw modifications. When tightened, the oxide layer on the titanium surface is scraped away, and the exposed reactive titanium is highly prone to cold welding (i.e., localized adhesion of metals in the solid state) with the caliper (typically made of aluminum alloy) under high pressure, causing the screw to become permanently seized. The Titanium Front Caliper Spacer creates a barrier between the two materials, fundamentally preventing this issue.

In humid environments, stock steel spacers or guide pins are highly prone to rust, flaking, and buildup. Once rusted, the surface becomes rough, directly causing the brake pads to fail to retract smoothly-resulting in "brake drag"-which makes the wheels harder to turn and increases fuel consumption. Most troublesome of all, in cases of severe corrosion, the spacer pins can become rusted solid to the caliper, making them extremely difficult to remove during later maintenance. The Titanium front caliper spacer never rusts, completely resolving this issue.

Rust and wear can cause a variety of noises. When caliper guide pins or spacers rust, the brake pads cannot separate properly, causing them to rub continuously against the rotor and produce high-pitched "squeaking" or "scraping" sounds. Additionally, a loss of elasticity in the original anti-loosening spring or wear on the spacer itself can cause play between the brake pads and the caliper bracket. When driving on bumpy roads or applying the brakes lightly at low speeds, the brake pads strike the caliper wall, producing a "clunking" metallic knocking sound. Our spacer is wear-resistant and prevents this from happening.
