The Power Stop S4994 brake calipers represent a high-performance upgrade specifically engineered for the front braking system of select 2006-2010 Ford Explorer and 2006-2010 Mercury Mountaineer models. Designed to replace stock calipers directly, these calipers come paired with brackets to ensure precise fitment and optimal functionality.

Power Stop is recognized within the automotive industry for delivering premium brake components that meet rigorous standards of safety and performance. Their manufacturing process, conducted at their Chicago, IL facility, involves remanufacturing calipers to exacting specifications and applying an electrostatic high-temperature red powder coating. This coating not only enhances aesthetic appeal with its vibrant finish but also provides robust resistance against rust and corrosion, thereby extending the service life of the calipers.
Each caliper undergoes comprehensive 100% pressure testing to confirm piston operation integrity and to prevent leaks, ensuring that every unit meets strict quality and safety criteria before reaching the customer. The assembly process incorporates new pistons, seals, slide pins (when applicable), dust boots made from high-temperature EPDM rubber, bleeder screws, and stainless steel brake pad abutment clips. The use of premium silicone lubricant further guarantees smooth operation and durability even under extreme driving conditions.
