Positive news at last for the automotive industry and the environment

The ultimate disk brake retraction system

Cut CO2 emissions

Minimise dust pollution 

Reduce rolling resistance 

Prevent brake fluid boil-off

 

Works in conjunction with the existing braking system.

 

Fits all types of disc brake:

      fixed, slotted, cross drilled, ceramic...

Description

There are two variations of the system:

 

Electronically controlled for highly efficient road vehicle use.

Accelerator linked for MotorSport use.

 

In both systems, during accelerator use, brake drag is removed via negative pressure within the master cylinder. Upon release of the accelerator, normal brake function resumes.

 

The systems act independent of other 'on-board' systems and may be used in conjunction with any type of disc or calliper design, with equal effect. It is fail-safe and cannot compromise normal brake usage.

 

Numerous tests have been conducted by a major brake manufacturer with results at elevated temperatures far exceeding expectations.

The image shows prototypes of both systems mounted on the master cylinder reservoir, along side each other for comparative purposes. Each use the same design principles of varying the air pressure within the master cylinder reservoir compared to that of atmosphere. 

 

Both systems sit comfortably in the palm of your hand.

Electronically Controlled AirBack® Brake Retraction System

During accelerator use, the system's miniature compressor switches on for a few seconds to reduce the air pressure within the master cylinder (M/C) reservoir whilst adding pressure to a separate miniature reservoir.  With continued accelerator depression, the M/C negative pressure will continually act to retract each set of the calliper pistons, the affect of which removes brake associated drag with no further compressor use or further power drain.

 

Upon release of the accelerator and before brake pedal application, the reservoir is arranged to release a positive supply of pressure to the M/C reservoir for a few tenths of a second (adjustably), after which it vents the M/C to atmosphere. The effect of the momentary addition of the higher air pressure is to pre-fill the M/C fluid system and remove any associated, brake pedal sink.

 

With adjustable M/C pressure and timer-on settings all brake drag may be removed with minimal power drain. Whilst this reduces CO2 emissions and brake dust pollution, it can further reduce brake pedal travel dependent upon it’s set-up. This effect will no-doubt improve motorist safety.

 

A flexible diaphragm is arranged to separate the M/C brake fluid and air supply to avoid cross contamination. The reservoir is arranged to be at atmospheric pressure upon brake application to avoid any effect on other on-board safety systems i.e. ABS etc. The system is fail-safe in operation, even with vehicle power supply interrupted or removed, mid cycle!

This design has no electronic controls and as such is believed to have potential for MotorSport application, rules allowing.

 

Activation/deactivation of the accelerator causes the change of pre-set pressures within the master cylinder (M/C) reservoir, with the compressor switched off during brake actuation. Both drag and M/C pre-fill effect can be observed and is preset/changeable, at will.
