Carefully pull the primary piston assembly and pin out of the bore and discard (Figure 6). The Primary Spring is not part of the piston assembly,
but may be pulled out with it. If this occurs, gently push the spring back into the bore while removing the piston assembly. Ensure that the pin is
removed with the primary piston assembly, and is not left in the cylinder bore.
Caution:
Be careful not to scratch or contaminate the new primary piston. DO NOT remove the blue installation tool from the new piston assembly.
Note:
The blue piston installation tool protects the piston surface during the assembly procedure, helps retain the pin in the piston assembly, and serves as
an inspection device to ensure proper assembly.
14.
With clean hands, rinse the inside of the master cylinder and lubricate the piston pumping cup and guide O-ring seal on the new primary piston
assembly with clean brake fluid conforming to DOT 3 specifications (Figure 7).
15.
The primary piston assembly has a pin installed into a hole in the piston. If the pin was dislodged from the assembly during shipping and handling,
re-insert the pin into the hole in the primary piston (Figure 7). Orientation of the slot at the end of the pin is not important. If necessary, pull the
piston guide back slightly to insert the pin.
16.
Push on the end of the blue installation tool to slide the guide tight against the pin. This will retain the pin in the piston assembly. Make sure the
pin is centered in the piston as shown in Figure 7 and does not extend beyond the piston flange on either side.
