HOW IT WORKS
Two part numbers fit all air brake slack adjusters
SINGLE PIN (ASCP1) Anti-Seize Cotter Pin
Used with all Haldex type slack adjusters that have just the 1/2” clevis pin
DUAL PIN (ASCP2) Anti-Seize Cotter Pin
Used with the Bendix type slack adjusters that use the 1/2” clevis pin and the 1/4” clevis pin
The Anti-Seize Cotter Pin holds the clevis pin stationary as the brakes are applied, forcing the slack adjuster bushing to rotate around the clevis pin each time the brake is applied.
Without these rotations, the clevis pin can become permanently seized due to corrosion on the contacting metal surfaces.
The Anti-Seize Cotter Pin keeps the cotter pin from seizing to the bore hole of the clevis pin because of the stainless steel properties and tension reflection movement between the cotter pin and the clevis pin bore hole.
Existing cotter pins, at times, seize to the clevis bore hole where a hammer and a punch is the only solution.
