So I decided to get my new WLA front brake linings bonded onto the old shoes because the old drum is so rough it will soon tear into the rivet heads. (Out of work, so on a real tight budget here)
But on reassembly, the shoes appear to be at least a quarter inch too short where they mate up to the cam. And they are about a quarter inch off matching the curve of the drum too.
I did not notice this problem on disassembly, so am pretty sure it fitted together in the normal way before.
Do you suppose the shoes contracted during the bonding process due to heat releasing stresses of a million duty cycles since 1942 and pulled the ends of the "C" in closer together?
Even with the offset cam lobes reversed, there is no way those shoes are close to mating up right.
Anyone ever come across this before?
And does anyone have a good set of WLA front shoes out there they could measure up for me?
Mine measure 6-1/4" across the outside of the "C" as shown in pic, outside edge to outside edge.
I want to make sure my problem is actually undersized shoes before I get new ones shipped from the US to Oz and not something else like mismatched other components etc.
Would be much appreciated if someone could give me a meausurement for new or newish shoes that fight right.
