Note:
If only the pad is being replaced, allow the pedal
to cool.
Note:
The bonding area must be clean, and free from
finger mar ks and fabric deposits.
Note:
It is essential to activate the surface and to wipe
in the same direction: there is a risk of contami-
nating the bonding surface when wiping.
Note:
Do not use the same paper to activate the sur-
face and to wipe the surface.
Throw the paper away after each use.

A poorly adjusted parking brake:
-prevents correct operation of the automatic compen-
sation system for the brake shoes,
-causes premature wear of brake shoes.
ADJUSTMENT
I - ADJUSTMENT PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) .
aApply the parking brake five times to condition the
cables for normal use.
aPut the parking brake lever into the released posi-
tion.
aCheck that the rear wheels turn freely. If they do not,
check the following components and if necessary re-
pair:
-the parking brake cables,
-the calliper piston,
-the automatic compensation system,
-calliper
aRemove the rear wheels (see 35A, Wheels and ty-
res, Wheel: Removal - Refitting, page 35A-1) .
aRemove:
-the heat shield clips (1) ,
-the heat shield (2) .II - OPERATION FOR ADJUSTMENT OF PART
CONCERNED
aLoosen the nut (2) to release the cables.
aPosition the parking brake lever at the 2nd notch.
aMove the adjustment nut until the disc or drum can
no longer be turned by hand.
aPull the brake lever several times.
aPut the parking brake lever into the released posi-
tion.
aThe disc or the drum must be able to turn freely. If
not, move the nut gradually until the disc or drum
can turn freely.
aRefit the rear wheels (see 35A, Wheels and tyres,
