Weve been receiving calls from both shop and home mechanics looking for a thin wrench to fit the centring flats, pivot nuts and lock nuts on many popular brake callipers
The new OBW-4 wrench is the answer. It has 10, 11, 12 and 13 mm openings and is specifically designed to fit the narrow flats found on some of these brakes that can make using standard wrenches difficult
This tool is particularly useful when working on dual pivot and side pull brake callipers seen on both current and older models from Campagnolo, Shimano, Sram and Tektro amongst others
Made from heat treated, nickel plated steel for long life and with a hole for hanging on your tool board
Made in the USA and covered by Park's legendary limited lifetime warranty
