Brake Specifications API: Get OEM Brake Data & Parts Fitment by VIN
Get brake type, ABS configuration, and front and rear rotor specifications by VIN or year, make, model, and trim. Access brake data in a JSON response, with specifications matched to the vehicle.
How the Brake Specifications API Removes Risk
Getting brake specs wrong isn’t like getting a trim color wrong. It affects safety, liability, and whether a part actually fits.
Eliminate Manual Data Entry Errors
No more transcribing specs by hand. Data is delivered exactly as verified every time.
Ensure Fitment Accuracy
Get precise, specific specs that match the right part to the right vehicle, reducing returns and liability.
Stay Current Without the Overhead
Specifications update automatically, so outdated data never makes it into your workflow.
Reduce Liability in Safety-Critical Applications
Brakes are safety-critical. Verified data gives you a consistent, defensible source of truth.

How the Brake Specifications API Works
Get brake information for all vehicles in three simple steps.
Step 1: Identify the Vehicle
Send a 17-character VIN or use Year, Make, Model, and Trim.
Step 2: Retrieve Brake Specifications
The API returns available brake information associated with the identified vehicle configuration.
Step 3: Get the JSON Response
Receive the vehicle’s engine specifications returned in JSON.
An Example Brake Specification Response
Here’s what a response looks like for an identified vehicle. Actual fields returned depend on what’s available for that configuration.
{
"status": "success",
"data": {
"vin": "WBX57DP04NN172527",
"year": 2022,
"make": "BMW",
"model": "X3",
"trim": "xDrive30i 4dr All-Wheel Drive Sports Activity Vehicle Automatic",
"brakes": {
"type": "4-Wheel Disc",
"primary_abs_system": "4-Wheel",

"rear_brake_rotor_thickness": "N/A"
}
}
}
- NOTE: Sample response is shown for illustration. Fields return "N/A" where the manufacturer didn't publish that spec for the identified configuration. Actual data availability depends on the vehicle.
What's Actually in a Brake Data Response
The API returns the core specifications that distinguish one vehicle’s brake system from another, including configuration type, ABS setup, and rotor sizing for front and rear.
System Configuration
- Brake type (e.g., 4-Wheel Disc)
- Primary ABS system
- Secondary ABS system, if the vehicle has one
Disc & Drum Configuration
- Front disc
- Rear disc
- Rear drum
Rotor Sizing
- Front brake rotor diameter
- Front brake rotor thickness
- Rear brake rotor diameter
- Rear brake rotor thickness

Who Needs This Level of Brake-Specific Data?
Brake specifications can support businesses involved in parts, service, vehicle sales, fleet management, and automotive software. Some common use cases are:
Parts Retailers & Aftermarket Platforms
Problem: The same model can carry different rotor sizes or disc/drum configurations depending on trim and drivetrain.
Solution: Use configuration-specific rotor and brake-type data to reduce mismatched parts and returns.
Repair Shops & Service Centers
Problem: Technicians need confirmed rotor sizing and brake configuration before ordering parts or beginning service, especially on unfamiliar vehicles.
Solution: Pull verified brake type, ABS configuration, and rotor specs during intake instead of researching each vehicle manually.
Automotive Marketplaces & Classifieds
Problem: Listings rarely go beyond “disc brakes” or “ABS,” leaving buyers without real detail.
Solution: Add brake type, rotor diameter, and ABS configuration to listings for more informed comparisons.
Fleet Operators
Problem: Mixed fleets can have different brake configurations even within the same vehicle model.
Solution: Standardize brake type and ABS data across fleet maintenance and safety records.
Insurance & Claims Platforms
Problem: Brake configuration and ABS setup can be relevant to safety assessments and claims review.
Solution: Add detailed brake data to existing vehicle assessment workflows.
Salvage & Recycling Businesses
Problem: Matching used rotors to compatible vehicles requires precise sizing, not just model-level guesses.
Solution: Use rotor diameter and disc/drum configuration data to confirm compatibility before resale.
EV & Hybrid Platforms
Problem: Regenerative braking can change how a vehicle’s brake system is configured compared to conventional vehicles.
Solution: Pull brake type and ABS configuration data specific to electrified drivetrains where available.
Precision vs. Guesswork: How the API Compares
Manually confirming brake specs usually means digging through parts catalogs, OEM service manuals, or forums and hoping the vehicle in front of you matches what you found. The API changes this.
| Brake Specifications API | Manual Lookup | |
|---|---|---|
| Vehicle Identification | VIN or Year, Make, Model, Trim | Search multiple sources |
| Trim-Level Accuracy | Exact vehicle configuration | Manual trim checks |
| Front/Rear Distinction | Separate front and rear data | Cross-reference required |
| Rotor Sizing | Diameter and thickness | Check catalogs and manuals |
| Source Consistency | Consistent field format | Formats vary |
| Scaling to Volume | Supports repeated lookups | Effort increases per vehicle |
| Software Integration | JSON API response | Manual data entry |

FAQs on the Brake Specifications API
What information does the Brake Specifications API return?
The API can return brake type, primary and secondary ABS system, front and rear disc/drum configuration, and front and rear rotor diameter and thickness, depending on availability for the identified vehicle.
Can I look up brake specifications by VIN?
Yes. The API supports 17-character VIN lookups for supported vehicles.
Can I search for brake data without a VIN?
Yes. You can use Year, Make, Model, and Trim to request available brake specifications.
Does the API distinguish between front and rear brakes?
Yes. Disc/drum configuration and rotor sizing are returned separately for front and rear, since the two commonly differ on the same vehicle.
Does the API return rotor size?
Yes. Available responses can include rotor diameter for front and rear brakes, and rotor thickness where the manufacturer has published it.
Why does rotor thickness sometimes return "N/A"?
Rotor thickness isn’t published by every manufacturer for every configuration. When it isn’t available, the field returns “N/A” rather than an estimated value.
Does the API include ABS information?
Yes. The response can include a primary ABS system, and a secondary ABS system where the vehicle has one.
Does the API identify drum brakes as well as disc brakes?
Yes. The response includes front disc, rear disc, and rear drum indicators, so vehicles with a disc/drum combination are identified accordingly.
Why do brake specs vary by trim if the model is the same?
Drivetrain, curb weight, and performance packages can all affect brake sizing. A heavier or all-wheel-drive trim may use a larger rotor than a base trim of the same model.
What vehicles are supported?
The API supports 17-character VINs and vehicles from 1981 to present.
How do I integrate the Brake Specifications API?
Send an authenticated VIN or year, make, model, and trim request to the appropriate endpoint and process the returned JSON in your application. The response can then connect to your existing parts, service, or fleet workflow.
Can I use the API without building an integration?
Yes. Teams that don’t need a custom integration can sign in to their Vehicle Databases account and access available data directly.
