(c) Using a union nut wrench, connect the 4 brake lines to the hydraulic brake booster assembly.
Torque:
15 N·m {155 kgf·cm, 11 ft·lbf}
NOTICE:
Use the formula to calculate special torque values for situations where a union
nut wrench is combined with a torque wrench (See page
).
(d) Connect the 3 connectors to the hydraulic brake booster assembly. |
