B: INSTALLATION
1. FRONT BRAKE HOSE
1) Route end of brake hose (on caliper side) through hole
in brake hose bracket at strut location.
2) Tighten end of brake hose at caliper using a union bolt.
Tightening torque (Union bolt):
18±3 N⋅m (1.8±0.3 kg-m, 13.0±2.2 ft-lb)
3) Secure middle fitting of brake hose to bracket at strut
location using a clamp.
4) Position disc in straight-forward direction and route
brake hose through hole in bracket on wheel apron side.
CAUTION:
Be sure brake hose is not twisted.
5) Temporarily tighten flare nut to connect brake pipe and
hose.
6) Fix brake hose with clamp at wheel apron bracket.
7) While holding hexagonal part of brake hose fitting with
a wrench, tighten flare nut to the specified torque.
