7. Remove the outboard piston from the caliper.
Label the piston so it can be reinstalled in its origi-
nal location.
CAUTION
In the following step, do not use a
sharp tool to remove the dust and pis
ton seals from the caliper cylinder.
Sharp tools could damage the cylin
der surface. The caliper will have to
be replaced if the cylinder surface is
damaged.
NOTE
Yamaha recommends servicing the
rear caliper without removing the cal
iper bolts (B, Figure 57). The caliper
halves have been separated for photo
graphic clarity. This caliper can be
serviced without separating the cali
per halves.
8. Use a piece of plastic or wood to carefully re-
move the dust seal (A, Figure 58) and the piston
seal (B) from their grooves in each caliper cylinder.
Discard all seals.
9. Clean all caliper parts and inspect them as de-
scribed in this chapter.
10. Inspect the caliper as described in Inspection
under Front Caliper in this chapter.
Assembly
NOTE
Never reuse the old dust seals or pis
ton seals. Very minor damage or age
deterioration can make the seals use
less.
1. Coat the new dust seal and piston seal with fresh
DOT 4 brake fluid.
2. Carefully install the new piston seal (B, Figure
58) and dust seal (A) into the grooves in each cali-
per cylinder. Make sure the seals are properly seated
in their respective grooves.
3. Coat the pistons with DOT 4 brake fluid.
CAUTION
Install each piston into its original
cylinder. The outboard piston must be
installed in the outboard side of the
caliper and vice versa.
4. Install the outboard piston as follows:
