The brake caliper is an important component of disc brakes and one that is subjected to high loads. In the car industry today, it is made of cast iron (GGG50) or aluminium. The brake caliper is an essential safety component that must withstand high thermal and mechanical loads. A key objective of machining processes is to achieve the highest levels of process reliability and dimensional stability. In the face of ever-increasing pressure from the competition, another indispensable ingredient of success is the ability to minimise per-part costs while maintaining superior quality in mass production. Our tools are up to the task.
1. Walter Prototyp Paradur® ECO-CI: Threading hydraulic connections and ventilation bores
The new Paradur® ECO-CI with innovative Xtra·treat™ surface treatment is the ideal tool for high cutting speeds and a wide range of applications. It is highly productive, wear-resistant, and reliable, making it the obvious choice for cost-effective cast-iron machining on a mass-production scale.
2. Walter Titex step drill: Boring, chamfering and reverse chamfering
With this solid carbide step drill with chamfer and reverse chamfer functionality, several machining steps can be performed without retooling. Cycle times are reduced as a result.
3. Walter disk set mill: Retaining flange milling
This tangential gang milling cutter is equipped with strong Tiger·tec® indexable inserts. Its fixed insert seat provides optimum stability and enables high feed rates. This results in short machining times and low per-part costs.
4. Walter B2084 combination tool: Brake piston bore roughing
The best way to achieve desirable per-part costs is to use a tool that can perform several machining steps in one operation. The Walter combination tool equipped with Tiger·tec® inserts provides maximum productivity and a high level of process reliability.
A moveable brake calliper can slide axially in relation to the brake disc, that is to say, it is float-mounted. As a result, the brake only has to be operated on one side. This saves weight and reduces costs. When pressure is applied to the brake, the brake holder ensures linear guidance, which allows the brake calliper to align itself in such a way that both brake pads are pressed onto the brake disc with equal contact pressure.

The anti-lock braking system (ABS) prevents the wheels from locking under heavy braking. It drastically improves driving stability, shortens the braking distance and the vehicle remains steerable, which allows obstacles to be avoided. More than two thirds of automotive manufacturers worldwide now equip their new vehicles with ABS.
