84. to each brake lever until the wheel locks When you apply one or both brakes the bike begins to slow but your body wants to continue at the speed at which it was going This causes a transfer of weight to the front wheel or under heavy braking around the front wheel hub which could send you flying over the handlebars A wheel with more weight on it will accept greater brake pressure before lockup a wheel with less weight will lock up with less brake pressure So as you apply brakes and your weight is transferred forward you need to shift your body toward the rear of the bike to transfer weight back on to the rear wheel and at the same time you need to both decrease rear braking and increase front braking force This is even more important on descents because descents shift weight forward Two keys to effective speed control and safe stopping are controlling wheel lockup and weight transfer This weight transfer is even more pronounced if your bike has a front suspension fork Front suspension dips under braking increasing the weight transfer see also Section 4 F Practice braking and weight transfer techniques where there is no traffic or other hazards and distractions Everything changes when you ride on loose surfaces or in wet weather It will take longer to stop on loose surfaces or in wet weather Tire adhesion is reduced so the wheels have less cornering and braking traction and can lock up with less brake force
