Brake Homologation 2026: What Vehicle Manufacturers and Importers Must Do

Key data

Manufacturers and importers of passenger vehicles, cargo vehicles and trailers operating in Europe face a new technical obligation. The United Nations Regulation No. 13, incorporated into the EU regulatory framework through its publication in the Official Journal of the European Union as DOUE 2026/746 on April 13, 2026, establishes the uniform requirements that braking systems must meet to obtain type homologation.

This is not a recommendation. It is the technical standard that national homologation bodies will apply in their evaluations. Those who do not comply will not obtain homologation. Without homologation, the vehicle cannot be sold in any of the markets adhering to the 1958 United Nations Agreement, which includes the entire European Union.

What does this regulation establish?

Regulation No. 13 sets three major blocks of requirements for braking systems of affected vehicles:

The regulation applies to three clearly defined vehicle categories:

• Category M: Motor vehicles intended for the transport of passengers
• Category N: Motor vehicles intended for the transport of goods
• Category O: Trailers

The standard is integrated into the framework of the United Nations Agreement of 1958, which means its scope of application extends beyond the EU: it affects all signatory countries of that agreement. For manufacturers with export aspirations, this is relevant: homologation in accordance with Regulation No. 13 opens markets outside Europe.

Economic and operational impact

Compliance with this regulation generates direct and indirect costs that companies must anticipate. The main operational impacts are:

• Review of technical documentation: All existing homologation documentation must be checked against the new requirements of Regulation No. 13. In fleets with broad model ranges, this can involve significant review work.
• Homologation tests: Vehicles must pass type tests in accordance with the new standards. These tests have direct costs and require coordination with accredited laboratories and technical bodies.
• Possible component redesign: In cases where current braking systems do not meet the new performance requirements, component redesign will be necessary. This is the scenario with the highest cost and impact on commercialization timelines.
• Coordination with national bodies: National technical homologation bodies will apply these criteria in their evaluations. Companies must anticipate the administrative timelines of these processes.

For importers, the impact is equally relevant: vehicles they import must have homologation in accordance with this regulation to be marketed. If the original manufacturer has not adapted its models, the importer will not be able to introduce them into the European market.

Who does it affect?

• Manufacturers of passenger vehicles (category M) that market in the EU or in countries adhering to the 1958 Agreement
• Manufacturers of goods vehicles (category N) with the same marketing scopes
• Manufacturers of trailers (category O)
• Vehicle importers of categories M, N and O in the EU
• National technical homologation bodies, which must apply the new criteria in their evaluations
• Suppliers of braking components whose systems are subject to redesign or recertification

Practical example

A Spanish importer bringing cargo vehicles (category N) manufactured outside the EU needs to verify that the original manufacturer has obtained type homologation in accordance with Regulation No. 13 for the braking system of those models.

If the manufacturer has not updated its homologation to the new standards, the importer faces two options: wait for the manufacturer to complete the homologation process—with the resulting delay in commercialization—or explore alternative models that already have current homologation.

In the case of a European trailer manufacturer (category O), the process involves reviewing whether the braking systems of its current models meet the performance requirements of Regulation No. 13, submitting the models to the corresponding type tests and updating technical documentation with the national homologation body. If any model fails the tests, it will need to redesign the affected components before it can continue to market it in the markets covered by the 1958 Agreement.

What should companies do now?

1. Identify affected models: Review the catalog of vehicles marketed or imported and classify them by category (M, N or O) to determine the scope of impact.
2. Audit current homologation technical documentation: Compare current documentation for each model against the requirements of Regulation No. 13 to identify potential gaps.
3. Contact the national homologation body: Consult the specific timelines and procedures that the national technical body will apply for evaluation in accordance with the new criteria.
4. Plan type tests: Reserve capacity in accredited laboratories for the required braking tests, anticipating typical waiting times in these processes.
5. Evaluate need for component redesign: If preliminary tests or technical review anticipate that any braking system will not meet the new performance requirements, initiate the redesign process with sufficient margin.
6. Verify supplier homologation status: For importers, confirm with original manufacturers that their models have or will have homologation in accordance with Regulation No. 13 before committing to orders.
