CLUTCH

Land Rover Monthly - - Lrm Technical -

1 This clutch mas­ter cylin­der reser­voir is empty be­cause the fluid was all drained off prior to chang­ing the old clutch slave cylin­der for a new one. 2 As the slave cylin­der is tricky to reach, a lit­tle fun­nel helps get the clutch fluid filled with­out caus­ing spillage and mess around the bulk­head. 3 The brake mas­ter cylin­der is empty be­cause the fluid had been drained in or­der to fit new brake pipes and flexi hoses, as well as brake calipers. 4 The brake and clutch fluid reser­voirs must be filled with fluid, be­fore any of the bleed­ing meth­ods are used – pres­sure, vac­uum or tra­di­tional. 5 Pres­sure brake bleed­ing tool has re­place­ment reser­voir cap and fits mod­ern brake and clutch fluid reser­voirs, with quick-re­lease hose at­tach­ment. 6 The reser­voir adapter cap is fit­ted in place of the orig­i­nal cap and tight­ened so that a good seal is cre­ated to en­sure fluid will not leak. 7 The pres­sure brake bleed­ing tool is filled with suf­fi­cient fresh brake fluid to com­plete the job. It can hold up to 2.5 litres of fluid. 8 The feed hose from the brake bleed­ing tool has a quick re­lease con­nec­tor which at­taches to the reser­voir adapter cap, al­low­ing the fresh fluid to flow. 9 The brake bleed­ing tool in­cor­po­rates a hand pump, which is op­er­ated to pres­surise the sys­tem – fluid will then flow when a bleed nip­ple is loos­ened.

10 For a con­ven­tional clutch sys­tem, as found in most De­fend­ers, a low pres­sure of around 12 psi is suf­fi­cient to bleed the sys­tem. 11 Clutch slave cylin­ders are usu­ally placed in a re­stricted lo­ca­tion and most are best ac­cessed from be­low the ve­hi­cle, par­tic­u­larly in De­fend­ers. 12 A tube is placed over the bleed nip­ple to di­rect emerg­ing fluid into a brake bleed­ing bot­tle with non-re­turn valve, as the air is ex­pelled from the lines. 13 The brake bleed­ing bot­tle costs around £25 and is quick and clean in op­er­a­tion. The clear tube al­lows for easy ob­ser­va­tion of air bub­bles and fluid. 14 This non-re­turn valve in the brake bleed­ing bot­tle is par­tic­u­larly use­ful when con­ven­tional two-per­son brake or clutch bleed­ing is be­ing car­ried out. 15 As soon as all of the air is ex­pelled and the sys­tem is filled with brake fluid, the pres­sure is re­leased from the tool by press­ing this valve.
