Acymner Disc Brake Caliper Tool Kit — 24‑Piece 45# Carbon Steel Set with 18 Adapters & Magnetic Thrust Bolts

Acymner 24PCS Disc Brake Caliper Tool Kit is a complete, heavy‑duty piston compressor set designed to retract caliper pistons and fit a wide range of American, European, and Japanese vehicles.

This kit bundles durable components and multiple adapters so mechanics and DIYers can compress caliper pistons, replace brake pads, and service disc brakes with one organized case. Built from 45# carbon steel with a rust‑resistant blasted finish and magnetic thrust bolts, the set focuses on repeatable performance and easy handling during maintenance tasks.

How does the kit make brake pad changes easier?

The Acymner kit streamlines pad replacement by supplying right‑ and left‑hand thrust bolts plus 18 adapters that match most caliper designs. The magnetic thrust bolt keeps adapters in place while you position the tool, reducing fumbling and speeding up the job.

• Includes two hand thrust bolt assemblies for both piston rotation directions
• Magnetic design prevents disc adapters from dropping
• Adapters cover a broad range of caliper shapes and sizes

What materials and construction ensure long life?

All critical parts are forged from 45# carbon steel and finished with a rust‑proof blast to stand up to shop environments. Threads and contact faces are sized for repeated use so the kit can handle professional or home‑garage workloads without premature wear.

• 45# carbon steel construction for strength and durability
• Rust‑proof blasted finish protects against corrosion
• Precision threads and machined adapter interfaces for reliable fit

Which vehicles will these adapters fit?

The 18 included disc adapters are chosen to cover common American, European, and Japanese models, making the kit broadly compatible with cars, trucks, and light SUVs. While it suits most applications, checking adapter fit against your caliper before beginning a job is recommended.

• Adapters fit a wide selection of modern caliper designs
• Suitable for cars, trucks, and 4x4 disc brake systems
• Helpful for both left‑ and right‑hand piston rotation needs

What comes in the case and how does storage help?

The set ships in a heavy‑duty carrying case with precision‑sized compartments for every component, keeping parts protected and organized. That layout reduces time spent hunting for adapters and lengthens tool life by preventing loose metal contact during transport.

• Complete set: right & left thrust bolts, two retaining plates, 18 adapters
• Includes a pair of gloves for cleaner handling during service
• Durable carry case with molded slots for each piece

Who is this for: the Acymner 24PCS Disc Brake Caliper Tool Kit is suited for professional mechanics, mobile technicians, and dedicated DIYers who perform routine brake servicing and need a compact, reliable piston compression solution. It’s ideal for anyone who values a broad adapter selection, robust materials, and tidy storage to keep brake maintenance efficient and repeatable.
