The cushion position will require changing in the wake of changing a brake cable, in the wake of putting in new cushions or as the cushions become worn. In a perfect world, the cushion position should be set with the goal that you can secure the wheel by pulling the brake switch most of the way to the handlebar. This gives you enough switch development for precise speed control, without the risk of catching fingers among switch and bar during crisis stops.
Mechanical disk brakes can be fiddly to change. The leeway among cushions and edge must be little, without permitting the cushions to rub on the rotor. A typical wellspring of disarray is that solitary the external brake cushion gets moved by the activity of the cable, pushing the rotor against a fixed internal cushion. This implies that the two cushions must be changed in various manners. You will genuinely profit by a work stand for this assignment. If that is impractical, persuade a companion to lift the wheel off the ground at ideal minutes.
Before you begin changing, turn the wheel, investigate the caliper space and check how much leeway there is among rotor and cushions. If the brake ties as you ride, one of the two cushions are scouring on the rotor and should be moved away. In case you’re finding that you can pull the rotor right back before the wheel locks, either of the cushions should be advanced toward the rotor.
The caliper opening is very restricted, and it tends to be precarious to perceive what’s happening. Clean the caliper before you begin attempting to make changes. At that point, hold something white on the most distant side of the space to make it simpler to see the hole. Turn the wheel while watching the opening. Except if they’re fresh out of the plastic new, rotors will frequently have a slight wobble. Ensure you change for an expected focal position.
Changing cushion position
Before you begin changing the cushion position, guarantee that the rotors are not delaying the side of the rotor opening — this will harm the rotors and moderate you down. Change the caliper position, with the goal that the rotor runs midway before you change the cushion position.
Watch that the wheel is appropriately and safely situated in the dropout as well — the rotor position will be influenced if the wheel’s not straight in the edge or forks. It merits keeping a different arrangement of brake cushions. There is no standard size and shape (dissimilar to V-brake blocks), so it tends to be dubious to locate the correct one.
Extras are light and straightforward to convey for crisis substitution. However, it’s far simpler to change cushions at home than out in the open because the occupation includes such a large number of little fiddly bits yearning to begin an existence of opportunity in the long grass adjacent to your trail.
