Bicycle Brake Caliper
Project developed by Albert Cowsky

Abstract
Brake Calipers are an important component required to build a bicycle. In order to build a cheaper, open source, bicycle, the calipers can be printed and fitted with brake pads. Open source bicycles could reduce the cost of transportation for people that cannot afford to buy a commercial bicycle. This project can be combined with others to make a largely cheaper and printable bicycle.
Bill of Materials
(Makes Two Calipers)
Files
Commercial Parts
- 2x Commercial Brake Pads Cost = $4.98
- 8x M6x1 Torx Bolts Cost = $0.63
- 8x M6 Nuts Cost = $0.04
- 1x Brake Line Guide Cost = $1.59 (For two)
Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
- If you used special skill – link to relevant wikipedia or wikiversity articles/courses
Technical Specifications and Assembly Instructions
- Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
- Include print time estimate
- Include assembly time estimate
- Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
- Consider video if appropriate

References
- The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did.

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
