So when it came time for SRAM to develop a new braking system, senior mountain bike brake engineer, Braden Snead put the brakes on Taperbore and started from scratch. The result is this brake right here, the Guide. He knew he wanted a more robust brake, so he designed the Guide around a timing port mechanism, a system common to many other mountain bike and motorcycle brakes. If air enters a timing port-type system, the bubbles are directed through the port into the reservoir, effectively self-bleeding the brake.
