in fig. 174).
12 On floater assemble stop washer .. 8», scraper

on floater.
13 Fi t the enti re assembly in the master cylin d er
hole,
fit
scraper ring rel ainer .. 10 .. in its housing
using a mallet to tap on tool 14926700 (10 fig. 174)
unti l the retainer is heard to click home.
14 Refit the complete master cylinder on the frame.
15 Refit con t rol lever on master cylinder body , se-
curing it

screw .<18», washer «16 .. , and nut .. 17 .. ,
16 Connect the fuel delivery pipe from master cylin-
der to con nector (tor model 1000 SP from master
cylinder to the connector with pressure control
valve).
17
Ae-check clearance between floater and lever
end on the master cylinder. To adjust, operate on
screws
"
15», after und oing nut
,, 17,.,
till the correct
distance is reached.
18 Fill up the reservoir wi th fluid up to its maximum
level.
19 Fully screw in plug and washer «14 .. on the
pump body.
NB Before mounting lightly moisten the rubber and
metal parts with brake fluid : under no circumstances
use mineral oils or grea ses.
23.13 BRAKE CALIPERS (FRONT LEFT AND REAR
FOR MOD El V 1000 G 5 - REAR FOR 1000 SP
(fig.
175)
1 The calipers consist of two light alloy bodies "2,,
and ,,3 .. joined up by two screws .. 8 ...

2 A round housing is machined in each caliper half
which acts as a piston guide (<<5»).
3 Sealing is ensu red by a gasket (,,4») lodged in a
groove inside the cylinder.
4 The sealing is automatically adjusted as with the
wearing of pads
«9»,
the piston exit out o f the cylin-
der housings increases.
5 Dust cap «6 .. prevents the entrance of moistness
and foreign matier.
6 The 2 pistons act directly on the 2 pads which are
secured by 2 pins ..
10 ...
Taper pin .. 12" pressed
by spring
«11 ..
prevents pad flapping and makes disc
setting easier after braking.
7 Cover .. 13 .. , elastically mounted on top of the
caliper prevents the pads from getting too much weI.

Brake fluid is delivered to caliper through the ho-
le in the half body. Hydraulic connection between
caliper bodies is through two inner holes. Sealing is
assured by gasket .. 7 ... Each caliper body is provided
with a drain plug .. 14 .. for air draining.
23.14 FRONT BRAKE CALIPER - 1000 SP
(fig .
176)
It is the same as for model V 1000 G 5 except that
the drain plug is litted on the caliper without any
ear.
A Inspections and c ontrols (fig. 177)
Every 5000 km (3000 miles) check pad wear as fol -
lows:
• Remove cap ..
A .. .
• Remove taper pin band .. D .. , spring " I .. , and pin
.C·
• Extract the pads. Thickness should be :
• new pad 9 mm
(.354"):
• wear li mit 6 mm (.236") .
If
under the wear limit, replace the pads. The fri c-
tion material should never be used to the point whe-
re the metal plate comes to the surface as if this
contacts the disc irreparable damage would ensue
and there would be no friction for thermal insulation
between fluid and pad .
Replace pads as follows :
• Push the pistons into the caliper bodies with
care so as not to damage the dust caps.
• Fit new pads ..
E".
• Fit pad retaining pins, spring. and center pin.
pin " B ...
After these pad replacing operations it is not neces-
sary to bleed the air from the braking circuits.
Al l that needs to be done is to actuate the handlebar
control lever or pedal several times unt il the plun-
gers re turn to their normal position (pads about
0.2 mm (.0078") away from the disc) .
Important Do not brake vigorously on new pads but
alto:ov them to settle down completely.
NB When replacing the pads it is welt to drain so-
me fluid from the reservoir as the return of the plun-
gers into the cylinder may cause overflowing in the
reservoir.
