AUTOFREN SEINSA D42878A Brake Pad Accessory Kit

Brake squeal and pad rattle are often traced back to worn or missing fitting hardware rather than the pads themselves. The AUTOFREN SEINSA D42878A accessory kit restores the shims, clips, and springs needed for a quiet, properly seated brake pad installation.

Key Benefits

The AUTOFREN SEINSA D42878A accessory kit is manufactured to support a quiet, secure brake pad installation. Here’s what this replacement part offers:

• Reduced brake noise from fresh anti-rattle springs and shims engineered to AUTOFREN SEINSA D42878A’s specifications.
• OE-matching fitment designed to match the original hardware set for your specific caliper and pad application.
• Even pad seating that helps promote uniform pad wear and consistent braking performance.
• Corrosion-resistant components designed to resist rust and seizing from road salt and moisture exposure.
• AUTOFREN SEINSA manufacturing standards, backed by a standard parts warranty against defects in material and workmanship.
