Why Missing Dust Caps Cause Seized Caliper Bleeder Screws

Overcoming Common DIY Installation Mistakes
Many Silverado owners accidentally damage new rubber caps by applying improper installation techniques.

Sharp tools can slice the flexible rubber, leading to premature tearing and seal failure.
Avoid using petroleum-based grease to lubricate the rubber cap during installation.
Petroleum chemicals break down synthetic rubber materials rapidly, causing them to swell and fall off.
Instead, use clean silicone grease if light lubrication is needed to slide the cap into place.
Ensure the metal bleeder screw is completely dry before snapping the cap shut tight.
