Front Brake: Avid BB5 Disc Brake Fine Tuning
Before each ride
Check cables for signs of wear or fraying. Squeeze the brake lever firmly and check for proper brake function. Adjust for pad
wear if necessary. Check pads for wear and replace if necessary. Ensure rotors are free of foreign substances and oils.
Cable Slack Adjustment
Use the barrel adjuster on the brake lever to remove any cable slack from the system. Turn the adjuster out until there is no
free play in the lever but not so far that the torque arm on the caliper is advanced. The torque arm should return completely
when the brake lever is released. If necessary, repeat pad adjustments. Note: new cables will stretch and require adjustment.
Pad Break In and Noise
It may take anywhere from 20 to 40 complete stops to break in Avid pads. You may begin to notice an increase in
braking power after the first ride. Brake noise can occur not only during the break-in period but off and on throughout the
life of the brake pads. Noise is dependent upon factors such as brake setup, rider weight, riding style, braking style, and
riding conditions (i.e. dust, soil, and contamination of friction surfaces).
Care and Cleaning
Extreme care must be taken when cleaning both the bicycle and its new disc brakes. Under normal use, it is not
necessary to clean the caliper, rotor or pads. If necessary, use only water and dish detergent to wash the caliper and
rotor being sure to thoroughly rinse all soap residues from the rotor. Dry with a clean paper towel.
Spring Tension Adjustment
If necessary, spring tension can be adjusted by turning the spring tension adjustment screw with a 2.0mm hex wrench.
Turning the screw clockwise increases spring tension, which equals harder lever pull.
Pad Wear Adjustment
Over time, you will need to compensate for brake pad wear. You can do so with two very simple adjustments: 1) Unscrew the
barrel adjuster on the caliper. 2) Turn the inboard red adjusting knob clockwise one or two clicks as needed to restore your brake
to optimum settings. Both of these adjustments move the pads closer to the rotors. Try different settings until the brake feels just
the way you like. IMPORTANT: Make sure you tighten the locknut on the barrel adjuster after you adjust. NOTE: While you can
perform a similar adjustment on the barrel of your brake lever, Avid suggests that you adjust for pad wear at the caliper. That way
you leave the brake lever for ON-THE-FLY adjustments.
Rear Brake: V-Brake Adjusting

The rear V-Brake system needs to be adjusted properly to offer
ultimate stopping power. There are two adjusting cable points. The
first is the proper adjustment and performed at the cable anchor bolt
attached to the top of the right side brake arm. The second is at the
brake lever adjusting barrel, which is a quick fix and should be
remedied with a proper cable adjustment. The arms can also be
adjusted for centering via the spring adjuster. The brake pads
should also be checked for rim alignment and wear.

To adjust, inspect the brake pads first. If the brake pad wear ridge
lines are gone and the pads are smooth, they need to be replaced,
refer to section d ―Brake pad replacement‖ of this chapter.

Next, check for centering of the pads. If the pads are not centered
to the rim, adjust the angle of the brake arm by either tightening or
loosening the spring adjust bolt with the Philips screw driver
included with the multi-use tool kit that came with your bicycle. The
bolt is located at the pivot point.

Pad alignment should also be adjusted if the pads are out of
alignment. Check to confirm the pad is properly aligned with the
curving of the rim and parallel to the rim surface. If needing to be
adjusted, use the 5mm hex key in the multi-piece tool kit that came
with your bicycle and loosen the pad fixing nut and align pads
properly with the rim surface and then re-tighten the shoe fixing bolt.

To adjust the brake arms for proper braking, first confirm the
adjusting barrel is screwed completely into the brake lever
assembly.

Loosen the cable anchor bolt at the top of right brake arm. Squeeze
the brake arms until the pads are less than 1mm from the rim's
surface. Re-tighten the cable anchor bolt. Cable anchor bolt
should be tightened to 55 lb*in.

The V Brake should now be properly adjusted. Test for braking, the
brake pads should lock the wheel at full pressure applied. If wheel
does not lock, check for oil or grease on the rim surface or pads and
clean. If brakes continue not to perform, bring your bicycle to an
Authorized Prodeco Technologies dealer.
CAUTION:
Be sure not to adjust the adjusting barrel on the brake lever assembly for a standard cable
adjustment. It will not allow for full brake lever modulation and have a bad influence on the brake performance.
CAUTION:
Brake pad replacement – check the brake pads for wear. If the pad's wear ridge lines are gone
and the pads are smooth, they need to be replaced for continued safe braking.
