Brake Service
Eventually the brake pads will wear out. Checking
and replacing these is a simple procedure that
can be done in the shop, with the exception of
having the rotor resurfaced on a lathe.
pads are located underneath the rotor as shown in
Figure 48, which is attached to the motor arbor.

shop if it has gouges in it. If visible cracks are
present in the brake rotor, replace it with a
new one. Remove oil and dirt from the rotor
with automotive brake cleaner. Once clean,
only handle the rotor with a dry rag and
install exactly the reverse of removal. Use a
C-clamp to compress the piston back into the
caliper.

Install new brake pads, mount the caliper
assembly by reversing
nect the air line.
