Manuals; Human Factors
April 2013; while performing a routine preflight inspection of a CRJ-700 aircraft; I noticed that the brake hydraulic lines were connected to the bottom two connection points on the Main [Landing] Gear (MLG). They should be connected to the upper two connection points instead. I notified the Captain of the problem and he contacted Maintenance and Dispatch. Maintenance confirmed that the hydraulic lines were installed incorrectly and needed to be corrected before departure; which they did. This action delayed our departure. This item/issue can be easily overlooked; and the flight may have departed in this condition; flight delay. [Recommend] check all Aircraft for this issue and correct.
