Brake pads and shoes are friction components that convert kinetic energy into thermal energy to slow or stop vehicles and machinery.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Thickness | 8-15 mm (new), 2-3 mm (minimum wear) | |
| Shear Strength | >15 MPa | |
| Compressibility | <2% | |
| Friction Coefficient | 0.35-0.45 (EE rating) | |
| Operating Temperature | -40°C to 600°C |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
A mechanical or friction-based device integrated into a furniture caster to lock the wheel in place and prevent unwanted movement.
A mechanical assembly within a wire tensioner that applies controlled braking force to regulate wire tension.
A mechanical assembly that applies friction to slow or stop the motion of end trucks in material handling systems.

Brake pads are used in disc brake systems and press against a rotating rotor, while brake shoes are used in drum brake systems and expand outward against a rotating drum. Pads typically offer better heat dissipation, while shoes are more protected from environmental elements.
Replacement intervals vary by usage (typically 40,000-70,000 km for vehicles), but should always be based on wear measurements. Industrial machinery follows maintenance schedules based on operating hours and load cycles. Always replace in axle sets.
Common causes include: vibration between pad and caliper (addressed with shims), glazed friction surfaces, worn hardware, or high-frequency resonance. Proper bedding-in procedures and quality components minimize noise.
