Defined Bite Point | Trickstuff

A clearly defined, constant and firm bite point supports the precise modulation of the brake and ensures reliable and predictable braking performance to maintain control even in critical situations and builds uncompromising confidence in your brakes.

In order to achieve a constant bite point, various factors must interact. In addition to the viscosity of the brake fluid, the rebound behavior of the caliper pistons plays a key role.

Ideally, all the pressure generated in the pump is transmitted via the brake hose to the pistons and the brake pads with minimal deformation. In particular the stiffness of the individual components contribute to the characteristics of the bite point. The higher the pressure within a brake system, the greater the mechanical demands on the stiffness of the overall system. As pressure builds, the components undergo minimal elastic deformation. All else being equal, the higher the transmission ratio of a brake, the more elastic the brake feels. The challenge is to efficiently transfer the hydraulic pressure in the brake pumps to the caliper pistons with minimal deformation of the components, such as the brake hose, brake caliper and even the pads. The less the individual components deform, the more defined and firmer the bite point will be.

Trickstuff brake systems are optimized for their intended use. The higher the required braking force, the higher the demands on the stiffness of the system to ensure a defined and firm bite point.

Brake hoses

The pressure stiffness of a brake hose has a significant influence on the bite point of a brake. Most Trickstuff brakes are equipped with high-pressure-resistant Kevlar hoses, which are not only extremely light at 17g/m, but can also withstand a maximum pressure of 630 bar.

Our MAXIMA is built with a Goodridge steel flex hose which can withstand a maximum pressure of 1350 bar and ensures immense stiffness due to its steel braiding.

Stiffness and construction of calipers

STIFFNESS & CONSTRUCTION OF BRAKE CALIPERS

A brake caliper with high stiffness enables a more direct and precise transmission of braking force, resulting in a clear and firm bite point. The two-piece Trickstuff brake calipers differ in terms of their design and are adjusted to their intended use and requirements.

In addition, the rollback behaviour of the caliper pistons has a decisive influence on the consistency of the bite point. Trickstuff brake calipers are designed with a short piston rollback, while tight manufacturing tolerances ensure that the pistons return evenly. This means that the brake pistons return to their original position within a very short time. This has the advantage of preventing the brake from being pumped up in quick braking succession and the free travel remains unchanged.

HOLLOW STAINLESS STEEL PISTONS

The light and hollow stainless steel pistons in the brake caliper make a considerable contribution to the heat management of the brakes. The hollow cylinder design reduces the contact surface between the brake pads and pistons to a minimum, while the stainless steel itself has low thermal conductivity, significantly reducing heat transfer into the brake caliper. In addition to stainless steel, air also has low thermal conductivity. The air cushion created in the hollow cylinder therefore also makes a positive contribution to heat management.

BIONOL AS BRAKE FLUID

The brake fluid used in Trickstuff brakes is Bionol, which is made from vegetable oil and is environmentally friendly.

The low viscosity of Bionol enables an easier flow through the brake system and therefore a constant pressure point and smooth running. Due to its high viscosity index, it is less susceptible to changes in performance at low temperatures.

A high boiling point of the brake fluid is crucial for consistent and safe braking performance, even under heavy use. If the boiling point is exceeded, this can lead to the formation of vapor bubbles and thus to a compression of the brake fluid, resulting in a loss of braking power. The boiling range of the low-viscosity Bionol is between 360°C and 420°C at atmospheric pressure and is therefore considerably higher than that of conventional mineral oils or DOT brake fluids.
