1. Pad/Rotor bed in procedures : Before you start, please note that TRP/Tektro
rotors use a harder steel that may require a slightly more extensive bed in
process than other makes, but they offer longer life. Please also note the pad
type used as metallic pads require a longer bed in process before being ready
to ride. Proper pad/rotor bedding is key to brake performance over the life of
the pads and rotors. Failure to follow these procedures will result in poor brake
performance for the life of the pads.
2. The following procedures are for new rotors and metallic pads. If using
semi-metallic pads or used rotors, the bed in process may be quicker. For
optimal brake performance, it is best to follow the complete instructions.
3. Begin by installing rotor and pads. Be careful not to touch the braking surface
of the rotor or pad to avoid contamination. Also the rotor may heat up during
the bedding process. Do not touch the rotor as it could be hot resulting in a
burn or bodily harm. If a used rotor in being matched with new pads be sure to
clean the rotor with isopropyl alcohol and a clean shop towel before
installing pads.
4. Once pads and rotors are installed, take your bike to a flat area clear of
obstacles. Pedal your bike up to 15 mph (24 km/h). Brake using the front brake
only until you decelerate to 5 mph (8 km/h) and release the brake. Be careful
not to engage the brake hard enough to stop the front wheel or lift the rear
wheel off the ground. Stopping the wheel with the brake engaged will hold a hot
pad to a hot rotor and can cause pad glazing which reduces brake performance.
Repeat this process up to 20-25 times or until full brake power is achieved.
5. Once you have successfully bedded in the font brake repeat the process with
the rear brake. When decelerating with the rear brake be careful not to stop
the wheel from spinning or skidding.

22.3. Brake Beding Procedure
To ensure optimal performance and rider safety please follow
these instructions.
Pad types
Semi-Metallic (Red Backed) :
The semi metallic compound will bed in quickly and operate with minimal noise but may
wear quickly in wet conditions compared to a full metallic compound. These pads are
best for riders looking for minimal noise, riding in dry conditions, or looking for
optimal modulation.
Full Metallic or Sintered (Copper Backed) :
These pads may generate more noise when cold. Once heated up during use they
should be relatively quiet. These pads will offer more bite, higher optimal operating
temperatures, and longer pad life over semi-metallic pads. Metallic pads are optimal
for riders looking for maximum braking performance, riding in wet conditions, looking
for maximum pad life, or looking for more bite/power.
