Maximum safety and minimal downtime: This is how you benefit from innovative braking systems for industrial applications.
Are self-adjusting brakes really completely maintenance-free?
Although referred to as ‘maintenance-free’, this primarily means the elimination of manual adjustment work. Regular inspections for wear of the brake pads and other components, as well as cleaning of the adjustment mechanism, are still necessary, to ensure optimal function and safety in continuous operation. For example, AL-KO recommends a shoe replacement every 5-6 years.
What specific advantages do self-adjusting brakes offer in industrial continuous operation?
They ensure a consistently high braking performance and shorter braking distances through automatic compensation of pad wear. This leads to less downtime (potentially up to 15% reduction), lower maintenance costs (up to 20% savings) and an increased operational safety of your systems.
Does the automatic adjustment also work in reverse?
In most systems, such as the Knott Premium ANS or AL-KO AAA, the adjustment mechanism is intentionally deactivated during reverse. This prevents unwanted tightening or blocking of the brake during reversing.
Can existing systems be retrofitted to self-adjusting braking systems?
Yes, retrofit kits are available for many common brake types (e.g., AL-KO drum brakes 2051/2361 or KNOTT types 20-2425/1), however, a compatibility check based on axle type, brake type and year of manufacture isabsolutely necessary . ATEK Drive Solutions is happy to advise you on this.. ATEK Drive Solutions berät Sie hierzu gerne.
What should be especially noted when installing self-adjusting brakes?
A proper installation is critical. This includes correct initial adjustment and tightening of fasteners with the specified torque (e.g., up to 800 Nm for AL-KO 2361). In case of uncertainty, a professional workshop should always be commissioned, to avoid safety risks.
Do I need a new TÜV certification after retrofitting to a self-adjusting brake?
Many self-adjusting braking systems from well-known manufacturers such as AL-KO or Knott have an EU type approval (e.g., ECE R13). If the installation is carried out correctly and manufacturer-compliant, often no additional TÜV test is necessary. The relevant documents (ABE) should always be carried.
Are there known problems or challenges with self-adjusting brakes?
Although they increase reliability, problems can occur. These include wear of the adjustment unit with high mileage or malfunctions due to ‘soft braking’,as some systems require strong braking to activate. Regular inspection and the use of original spare parts are therefore important..
How does the quality of the brake pads influence the function of self-adjusting systems?
The quality of the brake pads is crucial for overall performance and lifespan.It is strongly recommended to only use original parts or components approved by the manufacturer. Inferior aftermarket parts can reduce braking performance and accelerate wear on the system.
Self-adjusting brakes for continuous operation significantly reduce manual maintenance effort and can lower maintenance costs by up to 20%, but still require regular inspections..

Introduction to maintenance-free, self-adjusting brakes for continuous operation.
The importance of maintenance-free brakes in continuous operation.
Self-adjusting brakes for continuous use can reduce downtime (for example: 15% reduction), which minimizes production outages and maintenance costs. Although ‘maintenance-free’, they require regular inspections. Designed for demanding braking technology,they increase overall operational efficiency.
What are self-adjusting brakes?
They eliminate manual adjustments, automatically compensate for pad wear for consistent braking performance. Often, a strong braking action is necessary to activate them. AL-KO systems, for example, activate with sufficient gap, similar to a constant slip brake..Functionality and benefits of self-adjusting braking systems
How do self-adjusting brakes work?
A mechanism checks the pad distance during braking actions and automatically extends it if too much play occurs. The adjustment is often deactivated during reverse to prevent locking. The Knott Premium ANS brake uses this, shortens braking distances, increases safety – core technology of modern industrial brakes..

Diverse applications
Application areas range from mini loaders to conveyor systems. A maintenance-free self-adjusting brake for continuous operation is used in trailers, agricultural machinery, and industrial systems. Critical: correct design for load/use cycle. Stage technology brakes require different characteristics than logistics brakes; suitable brake design is crucial.
- These brakes are used in trailers, agricultural machinery, and industrial systems, from mini loaders to conveyor systems.
- A correct design that considers load and use cycle is crucial for function. brake designCompatibility must be carefully checked, with manufacturers such as AL-KO and Knott providing specific guidelines.
- Die Kompatibilität muss sorgfältig geprüft werden, wobei Hersteller wie AL-KO und Knott spezifische Vorgaben liefern.
- Important factors for compatibility, besides brake type, include axle type and year of manufacture of the vehicle.
- Systems such as AL-KO AAA are designed for AL-KO axles and Knott Premium ANS for KNOTT types; universal interchangeability is not given and poses risks.
- Retrofitting existing systems can extend maintenance intervals but should be done professionally and after a compatibility check, with pre-assembled shoes simplifying installation.
- In some systems, the initial inspection may be skipped after retrofit at 1,000 km, making early compatibility checks and professional installation even more important.
Check compatibility
The compatibility check is essential, especially for automatically adjusting brakes for continuous operation.Manufacturers (AL-KO, Knott) provide specifications. Besides brake type, axle type/year of manufacture is relevant. For Knott ANS retrofitting, VIN verification may be necessary.
AL-KO and Knott systems
AL-KO AAA for AL-KO axles/drum brakes (e.g., type 2051/2361). Knott Premium ANS for KNOTT types (e.g., 20-2425/1). Universal interchangeability is a misconception, posing safety risks. Information/retrofit kits available. See also electronic braking systems..
Retrofitting existing systems
Retrofitting (e.g., AL-KO Set AAA for type 2051) extends maintenance intervals. Pre-assembled shoes simplify installation. In some systems, the initial inspection may be skipped after 1,000 km. Compatibility checks/professional installation recommended.Maintenance, inspection, and potential problems
Maintenance despite self-adjustment
Even low-maintenance, self-regulating brakes for continuous operation are not entirely without care requirements. Manual adjustment efforts are eliminated, but wear parts (brake pads) require checks. Important: Cleaning the adjusting mechanism from dirt/brake dust. AL-KO recommends replacing the shoes every 5-6 years (material embrittlement).
Common problems and solutions
Brake failure (e.g. worn adjusting lever) emphasizes the need for inspection. Malfunctions due to ‘soft braking’ are possible, as some systems require strong braking for activation.
- Adjustment unit wear: Inspection/replacement.
- Blocked brakes (dirt): Cleaning/lubrication.
- Reverse automatic malfunction: Testing/repair.
Advanced monitoring: sensor-monitored brakes.
AAA brakes: Challenges and criticism
AL-KO AAA brakes are partially criticized (wear/unreliable adjustment). AL-KO: “Wobbliness” is construction-related (tolerance/dirt compensation). Correct initial installation/annual maintenance is crucial. Center brackets (since 2019) are meant to improve.
Inspection of the brake pads
Regular pad thickness check at maintenance-free self-adjusting brakes for continuous operation is essential; systems (e.g. AL-KO) provide inspection openings. Important: Quality of replacement pads – only original parts/approved components. Copies reduce braking performance.Costs, installation, and legal aspects
Cost factors
Acquisition costs for durable, self-adjusting brake systems: approximately 20-30% higher (Knott Premium ANS set approximately €300-350/axle). Long-term amortization through saved maintenance time/fewer failures. Costs for special tools (e.g. 800 Nm torque wrench for AL-KO 2361) should be considered for self-installation.
- Although acquisition costs are about 20-30% higher, they amortize in the long run through savings in maintenance time and reduced downtime.
- In the case of self-installation, potential additional costs for special tools, such as an 800 Nm torque wrench for AL-KO 2361, must be factored in.
- Installation, especially the correct tightening of the central nut (e.g. for AL-KO up to 800 Nm), requires expertise and often special tools, so consulting a professional workshop is advisable.
- All brake systems must comply with applicable regulations, such as ECE R13; many systems like the Knott Premium ANS already have type approval.
- Especially in the commercial sector, appropriate certificates should be considered, as the use of unapproved parts can jeopardize the operating permit.
- A TÜV inspection is not always mandatory if the products are type-approved (e.g. by AL-KO/Knott) and the installation is done correctly and in accordance with the manufacturer.
- Crucial for compliance and the waiver of an additional TÜV inspection are the approval for the specific vehicle model and adherence to the manufacturer’s installation instructions; ABEs should always be kept.
Installation
Some kits (AL-KO Set AAA) facilitate installation, while others require expertise. The correct tightening torque of the central nut (AL-KO up to 800 Nm) is critical, requiring special tools. Improper installation poses risks. Consult a professional workshop.
Legal aspects
Brake systems must comply with regulations (e.g. ECE R13). Many systems (e.g. Knott Premium ANS) have type approval. Important for commercial use. Pay attention to certificates; unapproved parts jeopardize operating permission.
