Hi, This pivot shoe measures same as your 15-178. 2 1/8" high; 1 1/4" wide and 17/32"thick across main body but is 9/16" deep at the brake. However, this brake is white while your 15/178 is brown. Is the 15-178 the correct pivot shoe? Thanks, John

Hi John,
The manufacturer changed the white brake to blue on this 15-188 pivot shoe, but the housing thickness is 1/2". If you are sure yours it is 17/32" thick, use the 15-178. Thank you!
