INSPECTION

I See Figure 64

The brake pads may be inspected without removal. With the front or rear
end elevated and supported, remove the wheel(s). On front wheels, unlock
the steering column lock and turn the wheel so that the brake caiiper is out
from under the fender.
View the pads, inner and outer, through the cut-out in the center of the
caiiper. Remember to look at the thickness of the pad friction material (the
part that actually presses on the disc) rather than the thickness of the back-
ing plate which does not change with wear.
Keep in mind that you are looking at the profile of the pad, not the whole
thing. Brake pads can wear on a taper which may not be visible through the

window. It is also not possible to check the contact surface for cracking or

scoring from this position. This quick check can be helpful only as a refer-

ence; detailed inspection requires pad removal.
