Pretrained computer vision classifier

Identify brake pad wear with one API call.

A pretrained brake pad wear classifier that sorts an image into one of 10 categories — the level of wear on brake pads. Use the brake pad wear API immediately, no training required, then adapt it to your own data when you need more.

Call the brake pad wear API

Once you've added this classifier to your console, you get your own copy of it behind your own endpoint. Invoke it with any HTTP client:

curl

curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
  -H "Authorization: Bearer $NYCKEL_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"data": "https://example.com/photo.jpg"}'

Python

import requests

# Get an access token: https://www.nyckel.com/docs/api/overview/authentication/
token = "YOUR_ACCESS_TOKEN"

response = requests.post(
    "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke",
    headers={"Authorization": "Bearer " + token},
    json={"data": "https://example.com/photo.jpg"},
)
print(response.json())

Example response

{
  "labelName": "Bald",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 10 brake pad wear categories, served on Nyckel's own infrastructure — your image stays on Nyckel.

Input
Image

Send an image URL or file to the invoke endpoint; the response is a label with a confidence score.

Make it yours
Adaptable

Clone it, then correct predictions and add your own samples in the console — Nyckel retrains automatically, turning this into a custom model tuned to your data.

More than a demo: this page is one of thousands of pretrained functions on Nyckel, an ML classification platform. You can invoke classifiers by API, review predictions, correct labels, collect samples from production traffic, and promote any pretrained function to a private custom model — without changing your integration.

Where teams use brake pad wear classification

Predictive Maintenance

The brake pad wear identifier can be integrated into fleet management systems to monitor the condition of vehicles in real-time. By predicting when brake pads need replacement, companies can schedule maintenance proactively, reducing downtime and expenses associated with unexpected repairs.

Safety Compliance Monitoring

Automotive service centers can use the brake pad wear identifier to ensure that vehicles meet safety regulations. This tool can quickly assess brake conditions during scheduled maintenance, providing reports that verify compliance and safeguard against liability issues.

E-commerce Quality Assurance

Online auto parts retailers can implement the brake pad wear identifier in their product listings. This feature can help customers identify the expected wear characteristics of their brake pads, ensuring they purchase quality parts suited to their specific vehicle needs.

Insurance Risk Assessment

Insurance companies can leverage the brake pad wear identifier in their vehicle evaluations. By assessing the wear level of brake pads at policy inception and renewal, insurers can adjust risk-based premiums, promoting safer driving habits among policyholders.

Driver Behavior Analysis

Fleet managers can analyze the data from the brake pad wear identifier to correlate brake wear with driver behavior. This insight can lead to targeted driver training programs that promote safer driving habits, potentially reducing wear and tear on vehicle components.

Condition-based Fleet Management

Logistics companies can implement the brake pad wear identifier for more efficient fleet management. By incorporating this technology, they can optimize replacement schedules based on actual wear, thus lowering the total cost of ownership and extending the life of vehicle components.

Aftermarket Support Services

Automotive repair shops can use the brake pad wear identifier to enhance their service offerings. This tool can help technicians provide customers with detailed assessments and actionable recommendations, improving customer satisfaction and driving repeat business.

Common questions

What's the difference between a zero-shot and a Nyckel-trained classifier?

A zero-shot classifier uses a large foundation model's general knowledge to pick between your labels — no task-specific training, so new or edited labels work immediately. A Nyckel-trained classifier has been trained on labeled examples and runs on Nyckel's own infrastructure, which typically makes it faster, cheaper per call, and more accurate on data that resembles its training set. The "Under the hood" section on this page shows which kind this classifier is, and any classifier can be adapted into a trained one by adding your own examples.

How do I know whether this will work for my application?

Honestly: we can't know in advance — it depends on your data stream and how closely it resembles what this classifier has seen. The reliable way to find out is to measure it on your own data: start invoking the classifier with real traffic, or upload and annotate a set of images in the console — make sure they look like your production data, not idealized examples. Nyckel's evaluation metrics then show you exactly how it performs on that data before you rely on it.

What happens when it makes a mistake?

No classifier is perfect, so Nyckel is built around the correction loop: invokes can be captured for review, you confirm or correct predictions in the console, and corrections become training data. Over time the model adapts to your data distribution — accuracy on your traffic improves with use rather than staying fixed.

Do I need training data to get started?

No. This brake pad wear classifier works out of the box — clone it into your console and you'll have your own API endpoint in under a minute. Training data only enters the picture when you want to adapt it: your corrected predictions and uploaded samples improve the model, and you can also edit the label set to match your needs.

What does it cost to try?

Trying the classifier on this page is free with no signup. Cloning it requires a free account, and the free tier covers your first API calls each month — see nyckel.com/pricing for current limits and paid tiers.

Ready to classify brake pad wear at scale?

Add this pretrained classifier to your Nyckel console — you'll get a live API endpoint in under a minute, and a path to a custom model when you need one.
