This will allow adequate clearance for pad removal and re-installation. Using the Torx wrench, back the inboard pad adjustment out all the way. Using the adjustment knob, back the outboard pad all the way out (turn the knob to left as far as it goes). Okay, now that you have a bit of background information, let us begin.įirst, remove your wheel from your bike. The inboard pad is adjustable during setup, but then remains fixed during operation. The second pad, the outboard, is the moving pad. This pad is attached to an arm on the caliper. This arm contains the cable clamping and rotates when the brake lever is depressed. This action moves the outboard pad inward toward the inboard pad, thus clamping the disc rotor. The caliper, the actual brake bolted to the bike, is made up of two brake pads-inboard and outboard-between which the rotor will be clamped to provide the braking. Gloves are an excellent option, too.īefore we begin, here’s a basic overview of mechanical disc brake parts.Ī mechanical disc brake is made up a brake lever, a caliper, a cable connecting the two and a rotor. Supplies Needed: Standard and needle-nose pliers, T20 Torx wrench, 5mm allen wrench, cotton swabs, rubbing or denatured alcohol, and replacement pads. The exceptions are that most other brands of brakes require an allen wrench for the pad adjustment and may have set-screws that lock pad placement in. Much of the information below is relevant to other mechanical brake models. Since the Avid BB7 model is increasingly common as stock equipment for commuting bikes, I chose to focus on this particular model for this month’s tip. This month’s shop tip covers pad replacement and adjustment for mechanical disc brakes.
