7.3.2 BRAKE CALIPER ADJUSTMENT

Adjust the calipers when:
•
the brake adjustment nuts are tightened all the way but
the steering lever travel still exceeds 7" or
•
the total clearance between the brake pads and the brake
disc exceeds .010".
To adjust the brake calipers:
1. Tighten the lock nut with a 1/2" open end wrench, no
wider than the thickness of the lock nut (Figure 7-21).
As the lock nut is tightened, measure the clearance be-
tween the brake disc and pad as shown in Figure 7-22,
using a .010" feeler gauge. .010" is the correct clearance
between the left brake pad and the brake disc when the
right pad is pressed against the disc.
2. Use another 1/2" open wrench to tighten the outer lock
nut to the inner one.
3. Tighten the adjustment lock nut with a 1/2" wrench so it
is snug but the bolt can still be turned freely with fingers.
4. Adjust the other brake caliper assembly by repeating steps
1 to 3.

• worn to 3 mm (1/8") thickness as shown in Figure 7-22;
• glazed and brake efficiency is affected; or
• contaminated with lubricant and brake performance is
affected;
• they are no longer serviceable and must be replaced.

To replace the brake pads:
Use an electric drill and 1/4" drill bit to remove the heads of
the rivets holding the old pads to the calipers. Clear the
remainder of the rivets from the calipers and install each
100-56 brake pad set (2 pads) using 8 of 120-09 rivets and a
pop riveting tool to fasten the pad in place. An ARGO dealer
will replace brake pads for you.
