Idea 18

This is NOT a proper tool to pinch off a flexible brake hose. This type of tool should never be used and even if you put padding such as a piece of hose over the tools jaw area this tool may easily damage a hose.

If a hose is pinched off as shown so no fluid and flow through its small internal passage area with a tool as shown damage usually occurs.

Idea 20

Note the internal damage from using clamping pliers such as that shown in Pic. 19. This hose will no longer allow the same volume of fluid to flow as the hose on the opposite side of the vehicle. This may give a pull upon initial brake application among other problems.

Idea 21

This hose has an internal “flapper valve” type of issue. Brake fluid will flow through the “flapper” but will not easily flow back the other way. This may prevent fluid application or hold fluid onto the caliper depending on the direction of flow in relationship to the “flapper” direction. Was this problem initiated by someone once improperly clamping a flexible brake hose? You don’t really know but it could easily be the cause of the problem.

Idea 21

Brake hoses are really not complicated items but a large dose of common sense and understanding must be applied to brake service situations and problems when the brake hose may be the cause of the problem. It is also commonly recommended to replace brake hoses is pairs as if one hose has a service problem the other, unless it was changed individually, may soon follow as its service life has been the same. Pay attention to the tips and recommendations in the previous images and be successful in your brake hose service.
