Abstract

  1. This project is an attempt to create a simple bicycle brake for the open source community. This brake relies on minimal hardware and uses scarp rubber for the brake pad material. If the users budget allows, conventional bike brake pads could be utilized. These brakes are adjustable to fit a multitude of bikes as long as they have a provision for brakes on the forks of the frame. These brakes are also lighter than conventional materials. Further improvement to this project could be made by making the parts parametric to be easily customized for any bike.

Bill of Materials

  1. 2 7mmx40mm bolts
  2. 2 7mm nuts
  3. 1 3mmX20mm bolt
  4. 1 3mm nut
  5. Scrap rubber for pad material
  6. Part Files [1]

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Pliers or tool to remove supports
  3. Basic Bike Maintenance tools

Skills and Knowledge Necessary to Make the OSAT

Technical Specifications and Assembly Instructions

  1. After Printing, remove supports from parts.

  3. Run the scrap rubber across the front through the slots
  4. (Optional Step) Secure rubber to the back of the brake pad with screws
  5. Attach the brake pads to each of the sides with nuts
  6. Mount the brakes on a bike with the center bolt

  7. Run the brake cable through the top and attach it to the
Print Time - Approximately 3 hours
Assembly time - 20 minutes



Common Problems and Solutions

Supports can be tricky to remove. Try reducing the amount of supports to make it easier to break them free.

Cost savings

Print cost $1
Hardware cost $3
Total $4
Commercial equivalent $18 - [2]
Cost Saving
$14 cheaper
77% cheaper
Potential for more savings by reusing parts from old brakes or fasteners on hand.

Benefited Internet Communities

Bike Forums [3] Cycle Chat [4] Bike Radar [5]
