Deze handleiding is het resultaat van het harde werk van onze geweldige studenten, en de iFixit-werknemers vonden de gids uitzonderlijk cool.

Inleiding

Brakes slow your bike down when you pull on the brake lever on the handlebar. The brake calipers are connected to the brake levers by a cable that squeezes the brake-pads that are attached to the brake calipers. When the brake pads contact the rims they slow down the rim of the wheel, slowing down the bike.

  5. Clean and lubricate the parts as necessary before reattaching the caliper arms. Bolt the caliper arms back on while making sure the the pin on the back side of the caliper arm lines back up with the one of the holes in the frame. Each side should be in the same hole.

  10. Tighten/loosen the tension adjustment screws on each the caliper arm to adjust the resting distance of each brake pad, so that each pad is equally distant from the rim. Tightening the screw will shift the caliper outward from the bike, loosening it will shift it inward. Tighten/loosen the brake adjuster on the handle bars such that when you clamp down on the brakes, the brake lever stops before hitting the handle bar. This will set the distance between the brake pads and the rim. Tighten the lock nut on the brake adjuster to permanently set its position.

“what does it mean if the point is red???? “

I believe that is indicating that this step corresponds to an image which highlights a specific step. I saw this two times, in step 4 and step 9. For step 4, it shows the highlight in the second image and for step 9, the highlight is in the first image. It seems that the red bullet point is just to make it easier to map the step to the image.

Hope this helps
