Benefits of technology

[0006]The invention also includes a self-winding supply reel system for an elongate member, said supply reel system comprising first and second reels mounted in spaced apart relation such that a distance between them reduces as said elongate member is drawn from said supply reel system and a resilient biasing device for increasing said distance to a place said reels in a rest condition in which said elongate member is substantially wound onto said supply reel system.

Problems solved by technology

Unfortunately the presence of water in a brake fluid lowers the boiling point (vapour lock point) of the brake fluid, which can result in a slightly “spongy” brake pedal feel.
The presence of moisture in brake fluid may even result in total brake failure.
The heat generated by brake use can elevate the temperature of the brake fluid to a point at which vapour (steam) bubbles form, which will cause instant and total brake failure.
Moisture in a brake fluid may also lead to component corrosion to the extent the component may fail.
This is both dangerous and potentially very expensive.
Having a new ABS unit fitted can easily cost US$1,000.

Embodiment Construction

[0021]Referring to FIGS. 1 to 3, a brake bleeding apparatus 10 comprises a wheeled cabinet 12. The cabinet 12 has two wheels 14 provided on an axle 16 (FIG. 2). The axle 16 is fitted to respective rearward protrusions defined at the bottom rear of opposed side panels 18, 20 of the cabinet 12. The cabinet 12 has feet 22 provided generally opposite the wheels 14 at the bottom front of the side panels 18, 20. The feet 22 may be parts fitted to the side panels 18, 20. In the illustrated embodiment, the feet 22 are defined by forward protruding portions of the side panels 18, 20. A push handle 24 is provided at the top rear of the cabinet 12 generally above the wheels 14. The push handle 24 is a generally circular section rod that is fitted between respective rearwardly projecting ears defined by the side panels 18, 20. A user can readily move the brake bleeding apparatus 10 from place to place by standing to the rear of the cabinet 12, grabbing the push handle 24 and pivoting the cabine...

Abstract

A brake bleeding apparatus comprises a supply receptacle for brake fluid for supply to a braking system, ducting for connecting the supply receptacle with the braking system and a vacuum source connected with the supply receptacle for de-gassing brake fluid stored in the supply receptacle.

Description

FIELD OF THE INVENTION[0001]The invention relates to brake bleeding apparatus.[0002]Brake fluid acts like a magnet to water to the extent it can actually draw moisture through flexible rubber brake hose. Unfortunately the presence of water in a brake fluid lowers the boiling point (vapour lock point) of the brake fluid, which can result in a slightly “spongy” brake pedal feel. The presence of moisture in brake fluid may even result in total brake failure. The heat generated by brake use can elevate the temperature of the brake fluid to a point at which vapour (steam) bubbles form, which will cause instant and total brake failure.[0003]Moisture in a brake fluid may also lead to component corrosion to the extent the component may fail. This is both dangerous and potentially very expensive. Having a new ABS unit fitted can easily cost US$1,000.[0004]It is desirable to be able to introduce new brake fluid into a brake system with minimum moisture ingress and to be able to replace the br...
