Kamrexi 4-piece 3/8" 11-point truck brake caliper socket set — compact heavy-duty for European calipers

Kamrexi 4PCS 3/8" 11-point truck brake caliper sockets are compact, heavy-duty tools designed to remove and install European air disc brake caliper fasteners quickly and reliably.

If you work on Bendix, Knorr-Bremse or similar European truck air disc brake systems, these 3/8" drive sockets provide a precise fit and durable construction for repeat workshop use. The set contains four nine-millimeter-length sockets (3x1.7cm) with an 11-point profile that matches common caliper hardware on Adb22x, Adb225, SN6, SN7 and SK7 style calipers. Built from wear-resistant steel, they are made to handle the torque of pneumatic and powered wrenching tools while remaining small enough to carry in a mobile tool kit.

What vehicles and calipers will these sockets fit?

These sockets were made with European commercial brake calipers in mind. They fit Bendix Adb22x and Adb225 families, and many Knorr‑Bremse SB, SK and SN series calipers, including SN6, SN7 and SK7 variants. Always confirm bolt head profile and size on the vehicle before ordering.

• Compatible with Bendix Adb22x and Adb225 calipers
• Fits Knorr‑Bremse SB, SK, SN series (SN6, SN7, SK7)
• 11‑point profile matches European caliper fasteners
• 3/8" square drive for most hand and air wrenches

How durable and safe are these sockets under repeated use?

The sockets are machined from tough steel to resist wear and reduce the chance of cracking when used with torque or impact tools. Their 11-point design distributes load across multiple contact surfaces, helping prevent fastener rounding while the solid material withstands workshop conditions.

• High-strength steel construction for longevity
• 11-point geometry lowers slippage and rounding risk
• Cushions impact to reduce brittle failure under torque
• Suitable for pneumatic and electric torque tools

Can I use these sockets with my existing tools and how compact are they?

Yes — each socket has a 3/8" square drive to fit standard torque wrenches, ratchets and many powered tools. At roughly 3 x 1.7 cm (about 1.18 x 0.67 in), they are compact, lightweight, and easy to store in a toolbox, drawer, or mobile service bag for roadside or shop work.

• 3/8" drive works with common ratchets and torque wrenches
• Compatible with air and electric impact drivers (as rated)
• Compact dimensions for efficient tool storage
• Four-piece kit covers multiple fasteners without mixing sizes

What comes in the package and how do I use them correctly?

The set includes four identical 11-point sockets sized for typical European truck caliper bolts. To use, attach a 3/8" ratchet, torque wrench, or compatible power tool, align the socket squarely on the fastener, and apply smooth controlled torque. Inspect fasteners for corrosion before removal to avoid damage.

• Set contains four 11-point 3/8" sockets
• Designed for removal and installation of caliper bolts
• Use with torque or ratchet tools; avoid excessive impact without inspection
• Keep sockets clean and dry to preserve fit and longevity

Who is this for: This four-piece Kamrexi socket set is aimed at professional truck technicians, fleet maintenance teams and experienced DIYers who service European-style air disc brakes. It’s ideal when you need a reliable, small-footprint socket that fits Bendix and Knorr‑Bremse calipers and performs well with powered or hand torque tools.
