Couplemate manufacturers and tests all square mechanical disc brake override axles.

Trailer Parts include

Mechanical Override Disc Brakes are simple brakes to understand and maintain. Ensure brake caliper adjustments are made on the caliper bolt and not the cable adjuster.

Couplemate installs the latest Al-ko calipers on all of our mechanical braking systems.

The force exerted during braking from the tow vehicle engages the override brake, which in turn activates the mechanical calipers causing braking.

Please note: We ask you for your face to face measurement of your axle.

The latest news on small axles causing trailer and caravan axle fatigue.


Did you know that the bolts holding in your caliper can unwind themselves on rough, corrugated roads?

Couplemate uses a medium-strength locktite on all mechanical caliper bolts.
