Differentiation
Caliper material
Designed to be stiff and lightweight, the STOLZ system uses forged aluminumalloy for set components and the STOLZ caliper is a double-acting (both side) cylinder type.
MCT machining that uses forged billet
It is formed through MCT Machining Center.  Differentiates with casting production which is an advantage of low production cost (makes the molten material pour into the die).
It is 100% compatible with all electronic devices including genuine ABS (OEM)
Braking performance
It provides a complete braking control
before the antilock brake system (ABS) is activated.
It also provides a braking force that depends on the
depth of the pedal and delays reaching the critical point.

SFZ Exclusive case
When you choose the Stolz brake SFZ Series, which aims for nothing but the best, you will receive it in an exclusive case.

CALIPER

  • The Stolz brake is designed for the maximum extreme conditions of the caliper, and is optimized to distribute and transmit forces based on research data that was accumulated for many years through structural analysis depending on the caliper’s specifications. It is also made lightweight by reducing or minimizing parts that do
    not receive forces.
  • It prevents thermal storage in the brake system, and maximizes safety and heat dissipation through thermal and flow analysis that considers all types of heat including heat that is released from a disc, heat that is transmitted from the pad to the caliper, and heat that is transmitted from the caliper to the brake fluid.
  • It is scientifically and delicately machined to lower frictional heat conduction, anduses forged aluminum alloy pistons for the maximum pedal effort.
  • The machining process of the MCT that uses a forged billet,Stolz’s unique identity, and a stepped air radiation fin that considers heat dissipationare used to increase the cooling efficiency.The triple groove dust seal is usedto prevent the entry of foreign substances.
TECHNICAL SKILLS
The caliper body is made of aluminum alloys, and it is optimally designed to keep a balance of force based on maximum stiffness. Forged aluminum alloys go through an ultraprecision machining and forming through the Machining Center Tooling System (MCT).

A stepped air radiation fin that considers heat dissipation

Most genuine calipers (OEM) are single-acting cylinder systems that transmit power only to one direction. They have an advantage of low production cost but they are heavy, limited in size for each cylinder, and have difficulty in delivering power evenly to the pads, resulting in reduced braking performance.

The STOLZ system resolved these drawbacks by adopting double-acting (both sides) cylinder type. It uses forged aluminum alloy and it can satisfy the requirements for lightweight, hardness, and performance.

BRAKE PAD

Stolz launches a new brake pad for the safety and convenience of customers

The Stolz brake pad is manufactured based on confidence on highperformance brakes, and shows a powerful braking force and possesses continuous technical development and the best quality.

  • Brake :
    It maintains the constant friction coefficient for repetitive braking at high temperature and has an excellent safety
  • Noise :
    Minimize noise by installing a vibrational absorption plate
  • Cleanliness :
    Non-Asbestos Organic (NAO) compound technology, which minimizes the contents of steel (the causes of brake noise and dust), is applied to the pad.
  • Disc rotor :
    Minimize disc damages that are caused by brake friction materials.

BRAKET

It is optimally designed for each model using the same forged aluminum alloys that were used in the caliper
It is also designed to withstand about 1.5 times of fatigue failure and the maximum stiffness.
The curved surfaces of the 3-D design are formed by the MCT
with an excellent machining accuracy to minimize the interference of the car’s body structure
SPRING :
It absorbs vibrations that were caused by the operation of the caliper, and the special spring washer is mounted to prevent the loosening of the bolt.
Stolz’s products, which have a laser-engraved logo, are distinct from other products.

CARBON CERAMIC DISC

About
It is an innovative disc rotor that specializes in a plate rib (a structure between the front and the back of the disc) to satisfy durability, stiffness, and heat dissipation
The disc rotor is designed as a two-piece type in consideration of the rotation of the disc rotor (disc plate and bell housing) that is to be controlled with the force applied to the caliper during braking. The aerodynamic system (curved lines are selected instead of straight lines) is applied during the design of the disc rotor rib, and the inner disc pin is also designed for a smooth fluid flow.
Stainless steel pins and oval pins are used to tighten the bell housing and the disc plate. These pins not only balance the stress that is applied to the disc and the bell housing with different materials but also prevent the transfer of frictional heat to the bell housing to reduce deformation and increase durability.
Differentiation

The ceramic carbon disc is manufactured by mixing carbon fiber with a specially treated silicon and ceramic at a high temperature and a high-degree vacuum state. It is lighter than cast iron, and has less thermal deformation and a low friction coefficient because of its high stiffness and thermal resistance. It has an excellent performance to maintain a braking force and is mainly mounted on racing cars or supercars.

The drilled disc rotor with an excellent heat dissipation lowers frictional heat, which is delivered to the pad and the caliper, and maintains the best performance (proportional to the number of holes).
