Brake Flexible Hose and Pipe Check
The brake hose assembly should be checked for road
hazard damage, for cracks and chafing of the flexible
hose, for leaks and blisters. A light and mirror may be
needed for an adequate inspection. If any of the above
conditions are observed on the brake flexible hose, it is
necessary to replace it.
Inspect the pipe for damage, cracks, dents and
corrosion. If any defect is found, replace it.

Brake Control System and Diagnosis:
Master Cylinder Check
Check for a cracked master cylinder casting or brake
fluid around the master cylinder. Leaks are indicated
only if there is at least a drop of fluid. A damp condition is
not abnormal.
Flushing Brake Hydraulic System
It is recommended that entire hydraulic system be
thoroughly flushed with clean brake fluid whenever new
parts are installed in hydraulic system.
Periodical change of brake fluid is also recommended.
Booster Operation Check
There are two ways to perform this inspection, with and
without a tester. Ordinarily, it is possible to roughly
determine its condition without using a tester.
NOTE
For this check, make sure that no air is in
hydraulic line.
Inspection without Tester
Check air tightness
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
