SwissStop recommends having Disc Brake Pads changed by a professional mechanic at your local authorized SwissStop retailer.

When changing disc pads please clean rotor of any particles and check function of the whole brake system.

Attention: pads must be bedded in to achieve optimal performance

Step 1. On a gradual downhill slope, drag each brake for 20-30 seconds, alternating between front and rear. Repeat 2-3 times.

Step 2. On a steeper slope, engage and drag the brakes for 10-15 seconds then increase lever pressure until the bike slows almost to a complete stop. Repeat 2-3 times.

Pro Tip: The front pads will have been heated more than the rear. To achieve optimal performance, exchange the front and rear pads then repeat Step 2.

CAUTION before replacing or exchanging brake pads it is essential to let all parts cool.
