This system allows easy alignment of the brake caliper to the rotor. This fixing system is similar to many brake pads on linear pull caliper rim brakes. Avid® disc caliper brakes use a ball-and-socket system for the caliper mounting bolts. Pad adjusting knob moves pad position relative to rotor. The Avid® mechanical disc brake for MTB bikes uses a brake lever designed for linear pull brakes. Prepare housing and wires as with rim caliper brakes.

The brake housing and brake wire are the same as with rim caliper brakes. The lever should be set for a comfortable reach and secured to the bar. With this design, the rotor will flex to push against the fixed pad when the brake is used.įlat handlebar brake levers used with mechanical disc calipers are compatible with the linear pull caliper rim brakes. However, alternative designs have one pad being fixed, with only one pad moving to contact the rotor. Depending upon the design of the caliper, both pads may move to contact the rotor. Mechanical disc calipers use two brake pads, one on each side of the rotor. Mechanical disc brake systems use calipers that are cable actuated, similar to rim caliper brakes, with an inner brake wire and housing pulled by a brake lever. Allow rotor and caliper to cool before touching or servicing.

The system can generate significant heat from slowing the wheel and bike. Disc brakes can be effective in wet weather where mud, dirt and water are a concern in braking.

Disc caliper brakes slow the bike by converting the speed and energy of the bicycle into heat. The brake pads are housed in the caliper and are forced into the rotor. Disc brake systems use a caliper mounted near the dropouts of the frame or fork ends, and a rotor (disc) mounted to the hub.
