Brake Pad Component Matching Guide: Steel Backs, Shims, Hardware Kits and Molds

Why component matching matters before an RFQ

Brake pad projects rarely depend on one item only. A brake pad manufacturer may need steel backing plates for production, anti-noise shims for product performance, truck or bus hardware kits for repair channels and molds or stamping dies for a new reference. If these parts are checked separately, buyers may receive mismatched drawings, inconsistent reference numbers or incomplete quotation details.

A better sourcing process starts with a matching file: model references, photos, drawings, sample information and packing requirements. Hangzhou Fuxin Auto Parts Co., Ltd. supports brake pad component supply under the Fuxin Brake brand, using factory-based production resources and custom development capability for suitable brake pad component projects.

1. Steel backing plates / steel backs

Steel backs are the base structure of the disc brake pad. For brake pad manufacturers, the key checks are profile, holes, ears, slots, sensor positions, thickness, material requirement, surface condition and bonding preparation. For distributors, the priority is usually accurate model matching and stable repeat orders for the target market.

• Send OE, WVA, FMSI, GDB or FDB references when available.
• Confirm whether the project uses an existing steel back or needs new stamping tooling.
• Provide drawings or physical samples for uncommon references, regional models or modified shapes.
• State the expected order quantity, market and packing method before final quotation.

2. Truck and bus hardware kits

Truck and bus brake pad hardware kits may include springs, clips, retaining pins, guide plates, bolts, anti-rattle parts and related fitting accessories. These small parts affect installation speed and after-sales feedback, especially for fleet repair, heavy-duty workshops and commercial vehicle parts distributors.

For a faster check, buyers should send kit content photos, caliper information, brake pad reference, coating preference and whether the kit is supplied in bulk, bagged, boxed or paired with pads. Fuxin Brake can check available hardware kit resources and discuss custom development when the sample or drawing is clear.

3. Brake pad shims and anti-noise layers

Shims help manage noise, vibration and contact between the brake pad and caliper. Depending on the program, buyers may request bare steel shims, rubber-coated shims, multi-layer shims, adhesive-backed shims or model-specific shapes. The correct shim should be checked together with the backing plate shape to avoid edge interference, wrong hole positions or packaging confusion.

• Provide shim drawings, sample photos or backing plate references.
• Confirm adhesive requirement, coating structure, thickness and left/right variants.
• For new shim projects, send samples or accurate drawings before tooling confirmation.

4. Brake pad molds and backing plate dies

When a model is not covered by existing resources, tooling becomes part of the sourcing plan. Brake pad factories may need pressing molds for friction production, while backing plate projects may require stamping dies. A realistic tooling discussion should include drawings, samples, expected volume, production schedule and trial sample expectations.

Fuxin Brake can review whether a project should use available components, modified development or new tooling. This helps overseas customers avoid opening unnecessary tools while still supporting new model expansion when there is a clear technical and commercial need.

Recommended matching file for overseas buyers

• Model list with OE / WVA / FMSI / GDB / FDB numbers.
• Product category required: steel backs, shims, hardware kits, molds or backing plate dies.
• Drawings, photos, samples or kit content images.
• Thickness, material, coating, adhesive and packing requirements where relevant.
• Target quantity, target market, shipment plan and label requirements.
