I have obtained a 7" TLS hub and wheel complete, without shoes. Bought new 7" TLS brake shoes and fitted them but alas the re-build will nnot fit into the hub, by a long way. When putting just the shoes into the hub they fit perfectly, nice and circular and a 17mm gapeither side. When fitted to the plate the gap goes to 32mm ? Yes the arms are let off and the right direction... Are there 2 types of shoes used on these brakes ? Oh yes the face on the shoes do not fit flush to the 'blind side'.. It seems to taper off... Just a bit miffed now as tried a second set of shoes and just the same... Help !!!!!!!!!!! .... Griff
