Pressing brake discs from the hub

Pressing brake discs from the hub

(Tool deployed : Truck brake disc press)

In order to press a brake disc from the brake lining, BAS Groep Nijmegen uses a special truck brake disc press fitted with a 100 ton double acting cylinder.


Volvo trucks are fitted with brake discs instead of brake lining. Replacing brake discs is an intensive job and involves an enormous physical demand on mechanics. In order to remove brake discs quicker, safer and more ergonomically from the hub, Holmatro developed a special brake disc press in collaboration with BAS Groep.

Up until now, mechanics lifted the hub from the axle by hand. The hub was moved to a press to press the brake disc from the hub using a pump truck. Because this workshop press had insufficient capacity, the brake disc often stayed fixed to the hub. If this happened, the mechanic would hit the disc with a hammer, until it sprang from the hub. This was an undesirable situation, so BAS Groep Nijmegen began looking for a solution.

Mobile and height adjustable lifting table with a rotatable construction

Pressing brake discs from the hub

The truck brake disc press consists of 2 components: a lifting table and a press. The lifting table is mobile, height adjustable and includes a rotatable construction which can be easily positioned on the axle over the wheel hub. Once the hub is secured, it can be moved on the lifting table to the press with no effort at all. No lifting activities needed!

Pressing brake discs with different outside diameters

The press has a capacity of 70 tons and four clamping blocks. The clamping blocks can be mounted at three positions, so that 3 different brake disc outside diameters can be pressed. The brake disc remains fixed in the clamps, while the hub is pressed out of the brake disc by the cylinder. With the brake disc remaining in the clamps, the hub hangs onto the rotatable construction on the lifting table for cleaning. After chipping clean, the new brake disc can be placed and the entire unit can be simply driven back to the truck's axle.
