Brake Pad Replacement Guide

Follow the steps below to replace the brake pads on your Ariel Rider e-bike.

Step 1: Remove the Old Brake Pads

1. Remove the wheel from the fork or frame.
2. Remove the pad retaining hardware:
   • Threaded bolt setup:Carefully pull the cotter pin from the pad retaining bolt. Then, use a 3mm Allen wrench to loosen and remove the retaining bolt from the caliper sleeve.

     

   • Split fixing pin setup: If your caliper uses a split fixing pin instead of a bolt, use needle-nose pliers to straighten the bent end and pull the pin straight out.
3. Using a plastic disc brake piston spreader (or a non-marring tool), push the pistons on both sides evenly back into the caliper housing to create space for the new, thicker pads.

   

When to replace your pads: Brake pads should be replaced once the friction material wears down to a total thickness of 2.2 mm (applies to both 4 mm and 5 mm base plate types).

Step 2: Install the New Brake Pads

1. Insert the new brake pads and metal spring clip assembly together into the caliper slot.
2. Secure the pads in place:
   • If using a retaining bolt: Slide the bolt back through the sleeve, torque it to 0.8–1.2 Nm, and reattach the cotter pin through the end of the bolt.
   • If using a fixing pin: Insert the pin through the caliper and pad hole, then bend the split end with pliers to lock it into place.
3. Reinstall the wheel, ensure the rotor is centered between the new pads, and pump the brake lever a few times to set the pistons.
