Brakes – Mechanical
Mechanical Drum Brakes
Mechanical drum brakes are used for applications where simplicity and robust components are required. The most popular method of operation is using cables. Reference to mechanical centre pull requires steel brake rods to be supplied and when fitted to an axle a load equalizer mechanism must be used.

Mechanical Disc Brakes & Hubs
Mechanical Disc Brakes
Disc brakes are used for applications where resistance to corrosion is paramount. The open nature of disc brakes makes washing after salt water immersion a simple task. Disc brakes also allow quicker cooling during brake applications and therefore the disc brake system is less prone to brake fade.
AL-KO mechanical disc brake calipers are hot dip galvanised for maximum salt water corrosion resistance. The bushes, springs and bolts etc are made from stainless steel adding to the excellent capacity of this product to continue to function after exposure to corrosive environments.
The mechanical caliper comes in two configurations, forward pull and centre pull as shown in the photos below.
Forward pull is used on beam axles whilst centre pull is used when the AL-KO Independent Rubber Suspension (I.R.S.) is used. The simple cable actuation of these calipers and their uncomplicated design makes servicing a task that can be carried out by the “handyman”, saving on servicing cost. AL-KO mechanical calipers are suitable for disc hubs and rotors of thicknesses from 12mm to 15mm
Mechanical Disc Hubs
Mechanical Disc Hubs and RotorsDisc hubs or rotors are available in untreated plain finish (”as cast”). Some disc hubs are also available in hot dip galvanised finish. With the hot dip galvanised finish, wheel bearings and zinc plated wheel studs are fitted and all appropriate surfaces are hot dip galvanised. On AL-KO disc hubs/rotors the friction surfaces are machined after the galvanising process to provide superior brake performance. Galvanise surface treatment left on the friction surface would dramatically reduce brake performance.
Disc hubs are cast to include the hub, which houses the wheel bearings, whilst rotors are fitted to a separate hub. AL-KO can provide disc hubs and rotors drilled to suit the majority of popular wheel drilling patterns ex stock and can manufacture to suit most other drilling patterns on request, depending on compatibility. The table below lists popular disc hubs and rotors.
Disc hubs are available in many formats, including undrilled, drilled, studded (with studs & nuts) and with full bearing kits.
It is important to select the appropriate brake capacity and to seek advice from AL-KO on the appropriate axle machining profile and bearing configuration to carry and stop the required load given the wheel size that is to be fitted.
Where the type of disc is referred to as “disc hub”, this is a one piece hub and disc combination and it is usually fitted with LM or slimline bearing types.
Reference to “disc rotor” indicates the rotor is fitted to the back of a large capacity hub and bearing combination such as 1.5 tonne or 2 tonne or larger.
Note: the braking capacity should be matched to the planned maximum trailer mass.
