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