Rear Brake Hose/Pipe
REMOVAL
1) Raise, suitably support vehicle. Remove wheel if necessary.
2) Clean dirt and foreign material from both hose end or pipe end fittings. Remove brake hose and pipe.
INSTALLATION
1) Install brake hose and pipe by reversing removal procedure, noting the following points.
Fill and maintain brake fluid level in reservoir. Bleed brake system.
2) Perform brake test and check each installed part for fluid leakage.
CAUTION:
Position clamps to white marks on two brake pipes.
Be sure to obtain more than 3 mm (0.118 in.) clearance between axle housing and brake pipe.
Install clamps properly referring to figure below and tighten bolts.
When installing hose, make sure that it has no twist or kink.
