The AAA automatic brake adjuster - AL-KO Automatic Adjustment can be retrofitted to most wheel brakes from model year 1999 onwards, with bolted-on brake back plates.
The AAA Brake system is always optimally adjusted by the automatic adjustment in the wheel brake, so you save valuable braking distance in a dangerous situation. Whenever the brake has excess play, the AAA automatically readjusts.
The reliability of the wheel brake remains the same, since the robust system is unchanged apart from the adjustment function.
The premium brake which adjusts itself
- The proven wheel brake with its superior braking values is supplemented by the automatic adjustment function
- Adjustment is disabled when reversing
- Suitable for wheel brake types 2051 and 2361 (from 1999 model year) and therefore for most trailers with AL-KO axles
- Quick and easy conversion by pre-mounted AL-KO screw system suitable for AL-KO axles
Your Advantage
- Greater driving safety with a braking distance that is up to 5 m shorter
- Greater ride comfort thanks to smooth braking without a jolting motion
- Lower maintenance costs due to extended service intervals and dispensing with the first workshop visit after 1000 km
- No requirement to present to the inspection authorities once again following installation
- Tip: Change over to the AAA Premium Brake the next time you change your brake linings, if not before
