Description

3 pin tool for rewinding rear BMW brakes. I designed the tool to work with a G30, but I think it will work with other BMWs models. The tool is reversable and allows you to either use the triangular pattern for best fit, or the head of the screws. Note: Do not attempt to use without screws installed, it will just shear off the triangular pieces. The design uses #8 x 32 x 1/2" allen head cap screws. For printer settings, beef up the perimeter to 8 and use 50% triangle infill for added strength. Basic PLA did the job. I used the tool successfully to complete a brake job, and redesigned it to improve strength and fit. Simply use a 3/8 ratchet and short extension, then turn clockwise and apply downward pressure. Depending on how tight your calipers are you may only get one use from these, but for a DIY job it works without buying any special tools to compress the caliper.
