Claims34
Brake bleeding apparatus comprising:
- a supply receptacle for brake fluid for supply to a braking system;
- ducting for connecting said supply receptacle with said braking system;
- and
- a vacuum source connected with said supply receptacle for de-gassing brake fluid stored in said supply receptacle.
Brake bleeding apparatus comprising;
- a first receptacle for replacement brake fluid;
- a second receptacle for used brake fluid;
- first ducting for connecting said first receptacle with an inlet of a braking system and
- second ducting for connecting said second receptacle with at least one outlet of the braking system,
- wherein at least one of said first and second ducting is supplied from a self-winding supply system comprising two reels mounted such that a distance between them reduces as said ducting is drawn from said supply system and a restoring device for restoring said distance to a distance corresponding to a fully rewound condition of said ducting,
Brake bleeding apparatus comprising:
- a supply receptacle for brake fluid to be supplied to a brake system;
- a receiving receptacle for receiving brake fluid from said brake system;
- a vacuum source communicable with said supply receptacle;
- a pump communicable with said supply receptacle;
- and
- means for retaining a vacuum in said supply receptacle,
- wherein said brake bleeding apparatus is operable such that when said pump is operating to pump brake fluid from said supply receptacle to said brake system vacuum in said receiving receptacle draws brake fluid from said brake system.
(canceled)
A method of bleeding a braking system, said method comprising:
- connecting a supply receptacle containing brake fluid to an inlet of a braking system and a receiving receptacle for receiving brake fluid to an outlet of said braking system;
- and
- applying a positive pressure to brake fluid in said supply receptacle to drive said brake fluid into said braking system and a lower pressure to said supply receptacle such that brake as brake fluid from said supply receptacle is driven into said braking system brake fluid from said braking system is drawn into said receiving receptacle.
A method of operating a brake bleeding system that comprises a supply receptacle for brake fluid to be supplied to a braking system and a vacuum source for applying a vacuum to brake fluid in said supply receptacle, said method comprising:
- operating said vacuum source to apply a vacuum to brake fluid in said supply receptacle to degas said brake fluid;
- and
- selectively isolating said supply receptacle for storing said degassed brake fluid in said supply receptacle under said vacuum.
