Park Tool OBW-4 Offset Brake Wrench Info
The Park Tool OBW-4 Offset Brake Wrench is built for precise adjustments on side-pull and dual-pivot rim brakes, especially where access is tight. Its slim offset shape lets you reach around brake calipers to center them easily without interfering with other components.
Featuring four common wrench openings (10 mm, 11 mm, 12 mm, 13 mm), this tool covers most nut sizes used on brake caliper pivot bolts. Its hardened construction ensures durability, while the offset design increases leverage and accessibility for home mechanics or pro shops alike.
