INSTALLATION INSTRUCTION
T731F DIRECT MOUNT BRAKE
General Safety Information
• Improper use of your bicycle’s brake system may result in
loss of control or an accident which could lead to severe
injury. Because each bicycle may handle differently, be sure
to learn the proper braking technique (including brake lever
force and bicycle control characteristics) for your bicycle.
Consult your bicycle dealer and/or the bicycle owner’s
manual and practice your riding and braking technique.
• Securely tighten the caliper brake mounting hardware to
the specified torque.
When re-installing, apply blue thread retaining compound to
the brake mounting bolts threads and tighten to specified
torque using a calibrated torque wrench.
A - TOOLS
T15 Torx – For mounting bolts
5 mm Allen wrench – For cable clamp screw
3 mm Allen wrench – For spring adjustment screws
4 mm Allen wrench – For brake pad adjusting bolts
2.5mm Allen wrench - For brake pad retainer screws
C - BRAKE SHOE SETTING POSITION
Adjust the brake pad position so that the shoe surface aligns
with the rim surface as shown in the illustration, tighten the
shoe fixing bolt.
Direction of
rim rotation
B - BRAKE INSTALLATION
Temporarily fasten the plastic retainer clip if not already
installed. Insert bolts into frame mounting holes and thread in
2 full turns. Remove the plastic retainer clip and thread the
bolts in fully, alternating between turns to prevent binding.
Mounting Bolt torque : 6-8 Nm
Squeeze the brake lever about 10 times to stretch the
cable and seat the housing. Check that the brake is
operating correctly and that friction is minimal. Brake pad
clearance will probably need to be corrected by
re-tightening the brake cable.

rim rotation
Toe-in
0.5mm
NOTE- TRP road brakes allow the angle of contact between
the shoe and the rim (Toe-in) to be adjusted. Adjusting the
Toe-in makes it possible to obtain smoother braking
operation.
• If the mounting bolt(s) become loose, this could cause the
brake to work improperly and cause an accident. This is a
particular danger with the front wheel as the rider may be
thrown forward resulting in serious injury.
E - CHECK
Squeeze the brake lever 10 times.
F- BRAKE PAD REPLACEMENT
Remove the fixing bolt. Remove the pad by sliding it along
the groove of the pad holder.

• Brakes designed for use as rear brakes should not be used
as front brakes and vice versa.
• Read the service instructions carefully prior to installing the
brakes. Loose, worn or damaged parts may cause serious
injury.
1. Plastic retainer clip
installed.
2. Line up bolts with mounting
holes in frame or fork.
4mm Allen key
• Be careful not to allow any oil or grease to get onto the
brake pads. If the pads become contaminated, they should
be replaced and the braking surface of the rims cleaned
carefully, otherwise the brakes may not work properly.
Final tightening
torque: 5-7 Nm
D - CABLE CONNECTION
NOTE:
• If using standard Tektro brake pads in combination with
ceramic-coated or carbon fiber rims, the pads will wear more
quickly than normal. Pads specifically designed for carbon
fiber rim surfaces are available from Tektro/TRP Brakes.
3. Leaving the clip installed,
start the threads of each
bolt 2 full turns.
FOR THE RIGHT
Same at front and rear
4. Remove the plastic
retainer clip.

Fixing bolt
Tighten the fixing bolt. Tightening torque: 1-1.5 Nm.

• Pads should be replaced if they have worn to the point that
the grooves are no longer visible.
Final tightening
torque: 2.5-3 Nm
• Parts are not guaranteed against natural wear or
deterioration resulting from normal use or crash damage.
• If you are unfamiliar with any element of assembly or
maintenance of this brake system, consult a qualified
mechanic or contact Tektro / TRP Brakes Customer Service.
FOR THE LEFT
Same at front and rear
1. Ensure that the cable barrel adjuster is seated in place.
2. Using the centering adjustment bolt for minor adjustment.
Turn the cable barrel adjuster to readjust the pad
clearance.
• Always make sure the front and rear brakes are working
correctly before you ride the bicycle.
• The required stopping distance will be longer in wet
conditions. Tires will also skid more easily, which can result
in loss of control. Reduce your speed by applying the brakes
early and gently.
There are two different types of pads and pad holders to
be used in the left and right positions. Slide the new pad
into the grooves of the pad holder making sure of the
direction and fixing bolt hole position relative to the recess
in the brake pad.

5. Tighten the bolts about 1
turn at time, alternating to
prevent binding.
Final tightening
torque: 6-8 Nm
6. Mounting bolt torque:
6-8 Nm, (53-73 in-lb)
