What Is a Brake Pad Backing Plate?

Why the backing plate matters

The backing plate is the structural base of a disc brake pad. It supports the friction material, transfers caliper force, controls fitment through ears, slots and holes, and affects noise, vibration, bonding strength and service life.

Key sourcing points for brake pad factories

For production use, buyers should check material grade, ordered thickness, profile accuracy, hole position, burr control, surface cleanliness and whether the plate is ready for friction material bonding. Fuxin Brake can supply surface requirements when required.

Material and dimensional control

Q235B and other low-carbon steels are commonly used for many aftermarket backing plates. For stable production, dimensions should follow the required FMSI, WVA, GDB or customer drawing references.

Surface preparation and bonding readiness

Shot blasting, clean surface treatment and correct adhesive-coating preparation help improve bonding with friction material and reduce delamination risk.

What to send for quotation

Send FMSI number, WVA number, GDB/FDB reference, drawing, sample photo, dimensions or target model list. If thickness needs adjustment, mention it before quotation.

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 backing plate thickness be adjusted?Yes. Thickness can be discussed according to customer requirements and production application.

Do you publish vehicle application data?Vehicle application can be checked separately. Public model pages focus on common references and dimensions.

Can Fuxin develop a new backing plate by sample or drawing?Yes. New backing plate models can be developed by sample, drawing, FMSI, WVA or OE reference.
