TEKTRO HDC300 Installation Instruction

General Warning & Cautions
- Disc brake calipers, rotors and pads get extremely hot when used. Serious injury could result from contact with a hot brake. Care should be taken not to touch the caliper, rotor
or disc brake while it is hot. Be sure to allow the brake to cool before attempting to service it in any way.
- Stop riding the bike immediately if the oil is leaking. Please carry on the proper repair, if you continue to ride with the oil spilling, the brake system may suddenly lose braking
power.
- Read instructions thoroughly before attempting any work on the Tektro hydraulic disc brake. If you are in any doubt, you should seek the advice of a Tektro Service Center or
other qualified mechanic.
- Be sure to confirm before riding the pads thickness must be more than 0.8 mm. Pads also must be kept clean and free from oil or hydraulic fluid.
- If the pads become contaminated you must discard them and replace them with a new set.
- The brake pads are specifically formulated to achieve optimum use with the Tektro hydraulic disc brake system.
Precautions
Methods for using mineral oil
1. Always use safety glasses when handing and be careful to avoid contact with eyes. Contact with eyes may result in irritation.
2. Use gloves when handing. Contact with skin may cause skin irritation, rash and discomfort.
3. Make sure you are working in a well ventilated area and cover nose and mouth with a respirator type mask. Inhalation of oil mist or vapors may cause nausea.
4. Do not drink. May cause vomiting or diarrhea.
5. Always keep out of reach of children.
6. Do not cut, heat, weld, or pressurize the oil container as this may cause explosion or fire.
Emergency care
1. In the event of eye contact, flush with fresh water and seek medical assistance immediately.
2. In the event of skin contact, wash well with soap and water.
3. If you inhale mist or vapor, go immediately to an area with fresh air, stay warm and stable and seek professional medical advice.
Disposal of used oil
1. Always follow local county and/or state codes for disposal.
2. Use care when preparing oil for disposal.
Directions for storage
After use, keep the container closed. Store in a cool, dark area, away from direct heat or sunlight.
Installation
A). Tools And Equipment Required
The following tools are necessary to install the Tektro hydraulic disc brake:
· 5mm Allen wrench
· T25 Torx® wrench
B). Mounting The Rotor
(1) Remove the wheel from the bike. Attach the rotor to the hub with the supplied Torx® bolts and tighten it with a T25 Torx® wrench. Final
tightening torque: 4-6Nm. [see photo b-1]
(2) Replace the wheel on the bike according to the manufacturer's instructions.
NOTE - The rotor must be installed with the "rotation" arrows pointing in the same direction as the forward rotation of the wheel.
C). Mounting The Brake Levers
Tighten the brake lever clamp in the desired position by tightening it with the 6mm Allen bolt. Final tightening torque should be 6-8 Nm.
[see photo c-1]
D). Mounting The Adapter
(1) Before installing the calipers, ensure each wheel axle is correctly seated in the dropouts (the brake rotor should be on the caliper
mounting side.)
(2) Select the correct adapter (front or rear) for the disc brake position on the bike.
(3) Holding the correct adapter, with the engraved 'F' or 'R' facing toward you (away from the rotor and wheel), position it behind the
frame/fork mounting holes. Bolt the adapter in this position to the frame/fork mounts. Now the engraved 'F' or 'R' should not be visible behind
the mounts. Tighten the bolts to a final tightening torque of 6-8Nm. [see photo d-1]
(4) Make sure the pads are correctly positioned in the caliper (see section on installing & removing pads), then place the caliper over the
rotor with the bleed screw facing away from the wheel. Attach the caliper to the adapter using the supplied Allen bolts. Do not tighten the
bolts at this stage. [see photo d-2]
(5) With the caliper mounting bolts still loose, depress the brake lever. The caliper will correctly center itself to the rotor. Keeping the brake
lever depressed, tighten the caliper mounting bolts. Final tightening torque should be 6-8 Nm.
