Brake calipers

Importance of Brake Calipers in the Brake and Braking System

In this category you will find a specialized range of brake calipers intended for the maintenance and repair of heavy-duty and industrial transport vehicles. These components are critical parts within the active safety system, responsible for applying the necessary pressure to the brake pads in order to stop the rotation of the disc and, consequently, the vehicle.

Our range is aimed at professional workshops and fleet managers seeking reliable spare parts for trucks, trailers and buses. Proper caliper operation ensures balanced braking, prevents uneven wear of other components and guarantees the vehicle’s appropriate response under demanding road conditions.

Key aspects for selecting the appropriate replacement

• Original reference (OEM): Verify the part number engraved on the old caliper to ensure full compatibility.
• Axle position: Confirm whether the required component is for the front axle, drive axle or trailer axle.
• Installation side: Calipers are not interchangeable from side to side; make sure to select left or right according to the direction of travel.
• System type: Identify the manufacturer of the braking system installed on the vehicle (for example, Knorr, Meritor, Wabco or Haldex systems).
• Repair kit vs. complete unit: Assess whether the damage allows repair using guides and seals or if replacing the entire caliper is necessary for safety.

Frequently Asked Questions

When should brake calipers be replaced on a heavy-duty vehicle?

Replacement or repair is recommended when fluid or air leaks are detected, if the pistons seize and prevent proper return, or if significant uneven wear of the brake pads is observed. They must also be replaced if the housing shows cracks or visible structural damage.

Do calipers include brake pads?

As a general rule, brake calipers are supplied as an independent unit. Brake pads, wear sensors and other installation accessories are usually sold separately or in specific kits, unless the product description explicitly states that it is a pre-assembled set.

What is the difference between a pneumatic and a hydraulic caliper?

In heavy-duty vehicles, pneumatic actuation (air brakes) is the most common system, where the caliper operates using compressed air pressure. Hydraulic systems are more frequent in light vehicles or vans. You must ensure that you select the technology corresponding to your truck’s braking system.

Is it necessary to replace both calipers on the same axle at the same time?

Although not strictly mandatory, it is highly recommended to maintain braking balance. If one caliper is new and the other old, they may have different response times and efficiency levels, which could cause the vehicle to pull to one side during braking.
