Power Stop S4728BLK Rear/Front Pair of High-Temp Black Powder Coated

In this review of the Power Stop S4728BLK rear/front caliper pair, the conclusion is straightforward: these calipers are for truck and SUV owners who want a durable, serviceable replacement that resists corrosion and stays functional under high heat. The reviewer found the electrostatic high-heat powder coat and high temperature EPDM dust boots to be the single biggest reasons to choose these calipers, since those features directly address the common failure modes of older brake components. The calipers arrive rebuilt with new seals, guide pins, bleeder screws and mounting hardware, making installation and long-term maintenance noticeably simpler.

Key Features

• High-heat powder coat: Electrostatic coating helps resist rust and corrosion so calipers retain appearance and function in road salt and wet conditions.
• Premium rubber boots and lubricant: High temperature EPDM dust boots and silicone lubricant provide smoother piston movement and extended service life in extreme heat.
• Complete rebuild kit included: New seals, caliper guide pins, dust boots, bleeder screws and stainless-steel abutment clips reduce installation time and downstream troubleshooting.
• Assembled and tested in Chicago: Every caliper is powder coated, assembled, and tested at Power Stop's Chicago facility for consistent quality control.
• Core return process: The product follows a formal caliper core return process to streamline exchange or core credit for shops and DIY installers.

Who It's For

This caliper pair is well suited to owners of compatible Chevrolet, GMC, Cadillac and Hummer trucks and SUVs from the late 1990s through early 2010s who need a reliable replacement with corrosion protection and rebuilt components. Mechanics and do-it-yourselfers who prefer receiving rebuilt calipers with new hardware will appreciate the saved time and reduced parts sourcing.

It is not aimed at drivers who need performance racing calipers or a cosmetic show-piece beyond the black powder coat. Customers who require a specific OEM cosmetic finish or one-off machine modifications should look elsewhere.

Pros & Cons

Pros

• Durable high-heat powder coat that helps prevent rust and keeps calipers looking good over time.
• Rebuilt with new seals, guide pins and hardware to reduce fitment hassle and future leaks.
• High temperature EPDM dust boots and silicone lubricant improve piston operation in extreme conditions.
• Assembled and tested in a dedicated facility for consistent quality control.

Cons

• Black powder coat is functional but not a custom cosmetic option for show vehicles.
• Fitment is limited to specific Chevrolet, GMC, Cadillac and Hummer model years listed by Power Stop, so confirm vehicle compatibility before purchase.
