Brake Line

Check for scratches, swelling, corrosion, traces of fluid leakage on the brake hoses or pipe joints.
Make sure that brake pipes/hoses do not interfere with adjacent parts and there is no loose connector/clamp during driving.
Check any trace of fluid leakage, scratches, etc. on master cylinder, wheel cylinder and hydraulic unit.

NOTE:

When the brake fluid level in the reservoir tank is lower than specified limit, the brake warning light on the combination meter will illuminate.
Visually check the brake hose for damage. (Use a mirror where it is difficult to see)
