Brake Pad Replacement - Prodeco Technologies Mariner User Manual

d) Disc brake pad replacement
A pad should be replaced when its total thickness (backing plate and friction material) is less than 3mm. 1. REMOVE
THE OLD PADS – Back the inner adjustment knob all the way out (counterclockwise). Pull the spreader clip from
between the pads, and then pull the pads out of the caliper one at a time. 2. INSTALL THE NEW PADS AND
SPREADER – Insert the new pads one at a time into the caliper. IMPORTANT: Once the pads are in the caliper, you can
slide the spreader clip back into position between the pads.
Installing the Cable
Pass the brake wire through the anchor bolt on the actuating arm. Cable slack may be removed with a fourth hand tool. Be
careful not to advance the torque arm as you pull the cable. Tighten cable anchor bolt to the specified torque. Use the barrel
adjuster at the caliper to remove any remaining cable slack (if there is any). Important: After the cable is anchored, check to
ensure there is no more than 20 mm (3/4 in) of excess cable beyond the anchor bolt and trim as necessary. NOTE: Make sure
the caliper barrel adjuster is screwed all the way in before installing the cable.
Align the Caliper
A. Use your fingers or a Torx® wrench to turn the inboard pad adjustment know clockwise until the rotor is centered in the
caliper. This positions the pads for the next step in the installation. B. Make sure the CPS bolts are loose enough for the
caliper to move freely. C. Squeeze the brake lever to compress the brake pads firmly on the rotor. D. While still holding the
brake lever, tighten the CPS bolts. Once they are tight, you can let go of the lever.
Rear Brake: V-Brake Pad Replacement

The replacement of the pads is fairly easy. You should first release the V-Brake to access the pads. To accomplish
this, the V-Brake needs to be released and open. To release the V-Brake, you will need to squeeze the Brake Caliper
Arms together and slide out the Inner Cable Lead (cable guide/noodle) out of the Cable Lead Hook unit. To explain in
further detail, the cable flows through a metal cable guide at the end of the housing which is called the Inner Cable
Lead with some bike shops naming it a V-Brake cable guide or noodle. This guide has a small tapered end which
slides into the keyhole shaped slot in the Cable Lead hook Unity which most bike shops naming it as the arm link. By
holding the arms together, this allows the V-Brake cable guide to slide out the keyhole and up and release the cable
pressure on the brake arms. The brake arms are now released and will open.

Remove the fixing shoe nut. This is the bolt that holds the brake pad onto the caliper. Slide the pad assembly out
and insert a new pad assembly.

Pad alignment should also be adjusted with the pads possibly being out of alignment. Check to confirm the pad is
properly aligned with the curving of the rim and parallel to the rim surface. Use a 5mm hex key to slightly tighten the
shoe fixing nut, align pads properly with the rim surface and then fully tighten the shoe fixing bolt.

The new pads will create for a tighter fit due to new pads having increased depth. You will need to adjust the cable
for the right fit. Loosen the cable fixing bolt at the top of right brake arm and slide the cable out 1 inch from the cable
fixing bolt and lock plate. It is now time to close the brake arms back up. Squeeze the brake arms together and slide
the cable guide back into the keyhole slot called the arm link / inner cable lead. You are ready to tighten the cable
for tension. Squeeze the arms until the pads are less than 1mm from the rim's surface. Tighten the cable fixing bolt.
Cable fixing bolt should be tightened to 55 lb*in.

Your bicycle now has new brake pads installed and your brakes should perform as new. If your brakes are not
performing as new, re-read section c ―Brake adjustments‖ of this chapter and re-adjust your brakes. If your brakes
still do not perform properly, bring your bicycle in to an Authorized Prodeco Technologies dealer.
