Bleed Tektro CD Brakes
Original alp bikes handle assorted braking systems, including CD brakes. Trustworthy CD brakes employ a hydraulic cable to interface the brake lever with the brake caliper. Bleeding the brake is a action whereby elderly fluid is forced from the brake limit and replaced with advanced fluid. Tektro hydraulic brakes are bled whenever air has gotten into the brake path. Air bubbles engender the brake to impression "spongy", and in consummation lessens the brake's effectiveness.
Instructions
1. Lay the bike in a bicycle repair stand. Position it so the Tektro brake reservoir cistern comprehend on the brake lever is analogue with the ground. Whether de rigueur, loosen the brake lever bracket mounting bolt with a 4 mm hex wrench, and position the brake lever so that the reservoir tank cover is still with the ground.
2. Custom a T15 Torx wrench and remove the two Torx screws atop the reservoir cistern include. Remove the vehicle subsume from the reservoir.
3. Check that no bubbles emerge from the bleed nipple into the tube. Only fluid should be emerging from the bleed nipple.7. Close the bleed nipple with the 7 mm box end wrench.
Fit a 7 mm box extent wrench on all sides of the pattern of the bleed nipple. Ante up the nipple a 1/8 turn to the left to ajar the bleed valve.
5. Squeeze the Tektro brake lever gently a couple times to impact the old brake fluid into the receptacle. Add fresh brake fluid into the reservoir as the old fluid leaves the system. Keep the reservoir topped off with fluid to prevent bubbles from entering the system.
6. Attach a bleed tube to the bleed nipple atop the Tektro brake caliper. Country the other boundary of the bleed tube in a receptacle, such as an empty bottle, to hire the brake fluid.4.
Check that the reservoir tank is filled to the top. Add further brake fluid if necessary.
8. Replace the reservoir cover and Torx screws. Tighten the screws, using the T15 Torx wrench
9. Remove the bleed hose from the bleed nipple. If the Tektro brake lever mounting bracket was loosened to reposition the tank reservoir, move the brake lever to its original position and tighten the mounting bracket bolt.
