Abstract
A hidden braking assembly provides a connecting unit disposed inside a main frame. The connecting unit comprises an upper stem connected to a brake handle, a lower stem connected to a brake unit, and an adjusting set fixed to the lower stem and penetrated by the upper stem. A locking part of the adjusting set is operated to quickly adjust a telescoping length of an upper and a lower frame of the main frame. The connecting unit is synchronically adjusted during the adjustment of the upper frame and the lower frame. After the adjustment, the locking part is fixed to a body part of the adjusting set so that the two frames and the two stems can be firmly positioned, thereby facilitating a rapid adjustment of the telescoping length of the main frame and the connecting unit, increasing a using convenience, and attaining a stable braking effect.
