13. Bend back the tabs of the locking plates ( 16)
and remove the four bolts (IS) securing the
vacuum shell (18) and abutment plate (17) to
the slave cylinder (26). Note the gasket (27).
14. Extract the guide piece (39) and secondary
cup (38) from the slave cylinder using a suitable
hooked tool; also the cup spreader (37) and
spring (36).
IS. Depress the hydraulic piston (32) against the
spring pressure by using the push rod ( 13) or a
suitable piece of -h in. (7.9 mm.) diameter brass
rod, and release the circlip (35). Removal of
the circlip will then release the washer (34),
distance piece (33), hydraulic piston (32), main
cup (31) and spring (29) complete with spring
guide (30) and spring retainer (28).
To inspect
If the air-valve, air-valve cover, pipe, or filter are
faulty a new air-valve cover assembly must be
fitted.
Examine all metal parts· for damage or wear, par
ticularly those listed below, and renew as necessary.
(o) valve piston (11)
(b) valve piston bore
(c) slave cylinder main bore
(d) push rod (13)
(e) distance piece (33).
To reassemble
Discard those parts for which replacements are
supplied in the repair kit. The remaining original
parts, apart from the air valve cover assembly•,
should be washed in industrial methylated spirit
and allowed to dry.
Just before assembling, the rubber cups and seals
should be dipped in Lockheed brake fluid of the
specified grade (see Section "P").
In order to fit the main cup (31) It will be necessary
to make up a fitting sleeve, the ideal dimensions
for which are as follows:
Inside diameter
Outside diameter
Length
Page 4S
0·688-0·690 in.
(17·-48--17·53 mm.)
0·9735-0·9745 in.
(23·73-23·75 mm.)
1 ·37-1 ·38 in.
(34·8-35· 1 mm.)
I . Position the slave cylinder (26) in the vice with
the hydraulic outlet facing downwards, taking
care not to overtighten the clamp.
2. Fit the spring retainer (28) into one end of the
spring (29) and the spring guide (30) into the
other end. ln�ert the spring assembly into the
slave cylinder bore, retainer end first.
3. Fit the main cup (31) by positioning the fitting
sleeve, previously made up, at the mouth of the
slave cylinder bore and passing the main cup
through it (lip foremost). Take particular care
not to turn back or buckle the lip.
4. Fit the hydraulic piston (32), flat face leading,
into the bore and holding the piston against
the spring pressure, fit the distance piece (33),
washer (34) and circllp (35). Use the push rod
(13), or a -h in. (7·9 mm.) diameter brass rod
to depress the piston when fitting the circlip.
Take care not to score the slave cylinder bore
with the circllp and after fitting check that it
is properly seated in its groove.
5. Insert sprln·g (36) into the slave cylinder bor,f
followed by the cup spreader (37), dished sid�
facing inwards. Next, insert the secondary
cup (38), hollow side facing inwards, ensuring
that it locates properly on the cup spreader
(see Fig. 23).
6. Fit the guide piece (39) in the end of the bore
with the flat side facing inwards.
7. Place the gasket (27) in position.
8. Offer up the vacuum shell (18) to the slave
cylinder (26), locating its base on the projecting
portion of the guide piece (39).
