There is provided a walker apparatus having a frame, a wheel pivotally connected to the frame, and a brake pad assembly. The assembly has a brake housing configured to partially cover the wheel. The assembly has a brake pad mechanism including a brake pad lever pivotally mounted to the housing. The brake pad lever is actuated via a first end and has a second end spaced-apart therefrom. The brake pad mechanism has a brake pad connected to the brake pad lever adjacent to the second end of the brake pad lever. The brake pad lever is spring-biased to position the brake pad spaced-apart from and adjacent to the wheel. The brake pad lever is configured to cause the brake pad to abut the wheel when the lever is actuated. The brake housing extends about the brake pad mechanism for fully protecting the brake pad mechanism.
