Slacken the other two nuts orremove them, as necessary.6 Remove the four nuts securing the servounit to its mounting bracket assembly, thenpull the servo forward to remove the innerservo support bracket (see illustration).7 Remove the spring clip and clevis pinsecuring the servo pushrod to the cross link,then lift out the servo unit (see illustration).8 Note that the servo unit cannot bedismantled for repair or overhaul and, if faulty,must be renewed.Refitting9 Refitting is a reversal of removal. Refer toSection 9 for details of refitting the mastercylinder.16 Vacuum servo unit vacuumhose and non-return valve -removal, testing and refitting1Removal1 Depress the brake pedal three or four timesto exhaust any remaining vacuum from theservo unit.2 Carefully pull free and detach the servovacuum hose from the servo unit. If the hoseis reluctant to move, prise it free with the aidof a screwdriver, inserting its blade under theflange of the elbow.3 Detach the vacuum hose from its inletmanifold connection. Depending on the fixing,undo the union nut and withdraw the hose, orpress the hose and its retaining collarinwards, then holding the collar in, withdrawthe hose.4 If the hose or the fixings are damaged or inpoor condition, they must be renewed.Non-return valve testing5 Examine the non-return valve for damageand signs of deterioration, and renew it ifnecessary. The valve may be tested byblowing through its connecting hoses inboth directions. It should only be possibleto blow from the servo end to the manifoldend.15.7 Spring clip (A) and clevis pin (B)securing servo pushrod to the cross linkRefitting6 Refitting is a reversal of removal. If fitting anew non-return valve, ensure that it is fittedthe correct way round.17 Handbrake lever -removal and refitting 1Removal1 Disconnect the battery negative (earth) lead(refer to Chapter 5A, Section 1), then chockthe wheels to secure the vehicle.2 Undo the bolts securing the front seats tothe floorpan, and remove both seats from thevehicle (see Chapter 11).
