• Worn or torn piston boots allowing dirt and moisture intrusion
• Reduced caliper piston movement leading to uneven brake pad wear
• Corrosion buildup inside the caliper bore affecting piston operation
• Brake noise or reduced braking efficiency due to seal failure

Installation Notes and Tips

Installation of the Dorman D670158 kit requires removal of the brake caliper and piston. Clean the caliper bore thoroughly before installing new seals and boots to ensure proper seating. Use appropriate brake grease (not included) to lubricate the piston boot and seal during assembly.
