Wilwood 150-9184K BP-10 D340 Brake Pads CPB Combo Parking Brake Rear Set

Vehicle Fitment

• Universal Fitment - Compatible with Wilwood Combination Parking Brake (CPB) Hydra-Mechanical Calipers using pad shape D340
• Suitable for rear axle disc brake conversions, drum-to-disc upgrades, drag race, street/strip, muscle cars, and light-to-medium dirt track applications

Fitment Notes

• Pad shape D340 - designed exclusively for Wilwood Combination Parking Brake (CPB) calipers; verify caliper compatibility before ordering
• Rear position only - CPB calipers are a rear-specific application
• Compatible with iron and steel rotors only - not for carbon ceramic rotors
• Not compatible with OEM stock calipers or OEM stock rotors
• Street use is acceptable; optimal operating range is 500°F-1000°F

Features

• BP-10 semi-metallic compound delivers medium friction with smooth, gradual initial response
• Flat torque curve provides consistent braking feel across the full effective temperature range
• Low abrasion on iron rotors - extends rotor service life compared to more aggressive compounds
• Low dust and low noise ratings - suitable for street and show vehicle use
• Beds quickly for fast break-in without excessive wear or heat cycling
• NSF International LeafMark certified - compliant with SAE J661 friction standards
• Suitable for drag race, street/strip, muscle car, and light-to-medium dirt track use
• Wear rate is low-to-medium at low temperatures and increases gradually as temperature rises

Product Description

The Wilwood 150-9184K is a BP-10 semi-metallic brake pad set engineered specifically for Wilwood's Combination Parking Brake (CPB) Hydra-Mechanical Caliper, using pad shape D340. The CPB caliper is a dual-purpose rear unit that uses hydraulic pressure for service braking and a mechanical locking mechanism for parking brake function - making it a popular choice for drum-to-disc conversions and rear disc upgrades on axles that cannot accommodate internal shoe parking brake systems.

The BP-10 compound strikes a practical balance between street manners and performance capability. It offers medium friction with a gradual, predictable response and a flat torque curve for consistent feel throughout its operating range. Low dust and noise ratings make it well suited for street, muscle car, and show builds, while its semi-metallic formulation handles drag race, street/strip, and light dirt track duty with low abrasion on iron rotors. Pads are not pre-bedded and require a proper break-in before use.
