Tip:
Hydraulic fluid flows from one caliper to the other caliper. Fluid flows through the connection O-
rings (
Figure 2 , item 7) and the hole in the spacer ( Figure 2 , item 10). When you disconnect the
calipers, hydraulic fluid can flow from the hole at the connection O-rings. Air can get in the line.
After you connect the calipers, you must bleed the system.
