Brake Pad Shims and Anti-noise Function

What a brake shim does

A brake pad shim is installed between the backing plate and caliper contact area. Its main function is to reduce squeal, vibration transmission and metal-to-metal noise.

Common shim structures

Typical options include single-layer steel shims, rubber-coated shims, NBR coated shims, multi-layer shims and adhesive-backed structures.

Why full model coverage matters

Brake pad factories often need shims matched to backing plate models. A supplier with full-range capability and custom tooling support can reduce sourcing complexity.

Custom development path

If the requested shim is not in the current range, it can be developed by sample, drawing, backing plate reference, FMSI/WVA number or OE reference.

What to send for faster checking

Send the backing plate number, WVA/FMSI/OE reference, shim photo, dimensions, material structure requirement and whether adhesive backing is needed.

Fuxin Brake sourcing note: Fuxin focuses on brake pad components — backing plates, shims, hardware kits, molds and backing plate dies — for brake pad factories and aftermarket customers.

FAQ

Can shims be matched with backing plates?Yes. Shims can be developed or checked according to backing plate references.

Do all brake pads need the same shim structure?No. Shim structure depends on NVH requirement, market level, caliper design and production process.

Can Fuxin develop new shim tooling?Yes. New shim tooling can be developed according to sample, drawing or model reference.
