BRAKES

Measure lining and metal pad together with a vernier

and if the thickness is found less than 6 mm anywhere

in the pad, it is time to replace them. Fig. 8

Caution:

When removing the friction pads, mark them to

ensure that the inboard and outboard pads will

be reassembled in their respective places, if the

pads have to be reused.

Do not polish the pads with sand or emery paper

as hard particles of sand or emery paper will

deposit in pad & may damage disc.

Note :

If you find any difficulty in swinging the caliper

up, after removing the sliding pin retaining bolt,

it may be necessary to push the caliper piston,

back along with the pad, using a screw driver,

after loosening the bleed screw. But make sure

to bleed the system if pedal is found spongy after

replacing the pads.

Always use genuine recommended pads for

replacement.

Do not contaminate the pad surface with grease

or oil.

INSPECTION :

Thoroughly clean the disc. If it is scored bad enough,

replacement of new pads alone do not give optimum

performance and service life. Hence follow

instructions as given to recondition the disc.

Check for the condition of the rubber dust boots (7)

of caliper pistons (6) & (4) of sliding pins (3). If

there is no visible deterioration in piston rubber boots

(7) and sliding pin rubber boot (4), new pads can be

fitted.

Check for the condition of the antirattle clips & if

found ok the same clips can be reused after

cleaning.

INSTALLATION OF PADS :

Insert both the pads in between the carrier and disc

such that the friction material faces towards the

disc.

After inserting push both the pads (8) against the

disc with both hands and swing down the caliper (1)

and fit bottom retaining bolt. (2)

Tighten retaining bolt (2) to a torque of 3.00 to 3.5

mkg. by holding the sliding pin. (3) Fig.9

Rotate the disc and make sure it is free to rotate. If

it is not free to rotate, inspect and make sure that

the pads are sitting square with the disc without

any tilt.

Follow same procedure for the other front wheel also.

Fit wheels, jack down the vehicle & release the

parking brake.

Tighten wheel mounting big bolt to specified torque.

CAUTION:

Apply brake pedal couple of times with the engine

started before taking the vehicle for a road test.

Before applying an emergency brake, it is

advisable to apply the brake gently several times

at 50 km (30 miles) per hour to allow the brake

pads to align. Heavy braking or prolonged braking

should be avoided in the initial 100-150 km

(60-90 miles) of run until the new pads are bedded.
