Wilwood BP-40 Brake Pad Set - Shape 6812 | Dynalite Pro Series / DLS Calipers (150-40-6812K)

Keep your Wilwood DPS or DLS caliper setup performing at its best with the Wilwood BP-40 brake pad set in shape 6812. The 150-40-6812K is a direct replacement pad set for Wilwood's Dynalite Pro Series (DPS) and DLS calipers using the 6812 pad shape — using Wilwood's BP-40 compound, a versatile street and track friction material that delivers strong, consistent braking performance across a wide temperature range for both road and performance driving applications.

Note: Verify your Wilwood caliper model and pad shape before ordering. Wilwood calipers use specific pad shapes — shape 6812 is correct for DPS (Dynalite Pro Series) and DLS calipers. Using the wrong pad shape will result in incorrect fitment.

Key Features:

Performance Benefits:

• Wide Temperature Range: BP-40 compound is effective across a broad temperature range — from cold street driving conditions to the elevated temperatures generated during track use — providing consistent braking performance without the cold-ineffectiveness of more aggressive race compounds
• Strong Initial Bite: BP-40 delivers strong initial bite for confident braking response, whether in street traffic or approaching a braking zone on track
• Good Modulation: Consistent friction characteristics allow precise brake pressure modulation — important for trail braking and threshold braking techniques on track
• Rotor Friendly: BP-40's compound formulation is compatible with Wilwood's iron rotors for normal street and track use without excessive rotor wear
• Direct Replacement: Shape 6812 is the correct pad shape for DPS and DLS calipers — direct drop-in replacement with no modification required

What's Included:

• Wilwood BP-40 brake pad set — shape 6812 (150-40-6812K)
• Note: Hardware and shims — verify if included with Wilwood documentation

Installation Notes:

• Clean caliper pistons and slides before installation
• Inspect rotors for wear, scoring, and minimum thickness before installing new pads
• Compress caliper pistons fully before installing new pads — use appropriate piston tool for your caliper type
• Torque caliper hardware to Wilwood specifications
• Pump brake pedal to seat pads against rotors before driving
• Perform brake pad bedding procedure after installation — critical for BP-40 compound performance and longevity

Brake Pad Bedding Procedure:

New brake pads — particularly performance compounds like BP-40 — must be properly bedded after installation to transfer an even layer of friction material onto the rotor surface and to thermally cure the pad compound. Skipping or rushing the bedding procedure results in uneven pad material transfer, glazed rotors, and reduced braking performance. For the Wilwood BP-40 compound, a typical bedding procedure involves a series of progressively harder brake applications from increasing speeds, allowing the brakes to cool between each application. Refer to Wilwood's recommended bedding procedure for the BP-40 compound for specific instructions — do not make hard stops from high speed immediately after installation before the pads are properly bedded.

Wilwood BP-40 Compound — Overview:

The Wilwood BP-40 is a semi-metallic brake compound designed to bridge the gap between street-oriented OEM-replacement compounds and aggressive race-only compounds. BP-40 is effective from cold — providing usable braking performance in street driving conditions without the warm-up requirement of race compounds — while also maintaining consistent friction at the elevated temperatures generated during track use. This makes BP-40 a popular choice for vehicles that see a mix of street driving and occasional track days, where a single compound must perform acceptably in both environments.

BP-40's friction characteristics provide strong initial bite with good modulation — the driver can feel the brakes building force progressively rather than experiencing an abrupt on/off feel. This modulation is important for performance driving techniques like trail braking, where the driver is progressively releasing brake pressure while turning into a corner, and threshold braking, where the driver is maintaining maximum brake pressure just below the lockup point. BP-40's consistent friction across its operating temperature range makes these techniques more predictable and repeatable than compounds with a narrower effective temperature window.

Wilwood DPS and DLS Calipers — Context:

The Wilwood Dynalite Pro Series (DPS) is one of Wilwood's most popular caliper families — a lightweight, high-performance 4-piston caliper used extensively in custom brake system builds for street and track applications. The DLS (Dynalite Single) is a related single-piston caliper in the Dynalite family. Both calipers use the 6812 pad shape, making the 150-40-6812K the correct replacement pad set for either caliper. The DPS and DLS are commonly used in Wilwood's complete brake kit offerings for a wide range of vehicles, as well as in custom brake system builds where the caliper is selected for its combination of performance, weight, and adaptability.

Why Wilwood?

Wilwood Engineering is one of the most respected brake system manufacturers in North American motorsport, with decades of experience developing brake components for drag racing, road racing, oval track, and off-road competition. Their brake compounds are developed with genuine knowledge of friction material science and brake system dynamics, and their pad lineup covers a wide spectrum from street to full race applications. For builders running Wilwood DPS or DLS calipers who want quality replacement pads from the original manufacturer, Wilwood's BP-40 is the proven, trusted choice.

Perfect For:

• Wilwood DPS (Dynalite Pro Series) caliper users needing shape 6812 replacement pads in BP-40 compound
• Wilwood DLS caliper users needing shape 6812 replacement pads for street and track use
• Custom brake system builds using Wilwood DPS or DLS calipers wanting a versatile street/track compound
• Track day drivers wanting a compound that works from cold on the street drive to the track and performs consistently through a track session
• Anyone needing genuine Wilwood BP-40 replacement pads in shape 6812 for their DPS or DLS caliper setup

Perfect For: Wilwood DPS and DLS caliper users needing shape 6812 replacement pads in BP-40 compound for consistent street and track braking performance.

Pro Tip: Always confirm your pad shape number by checking the existing pad's backing plate before ordering replacement pads — the shape number is stamped or printed on the metal backing. Wilwood offers multiple compounds in the same pad shape, so also consider whether BP-40 is the right compound for your use case, or whether a softer street compound or harder race compound would better suit your specific driving application.
