Shimano 500 Brake Arm Alignment
I need some more eyes on these brakes. The first photo is of the front brake on my latest boomer project, the second is the rear and the third is a picture I found online. It is hard to see in my first picture, but the toe in is not bad. However the rear brake is toed out so bad I'm not even going to try to bend anything to get them toed in. Even though my head is not in the game lately, there is no way I got them put together incorrectly and all the bushings and washers are present. While the quick release cam/cable guide line up well on the front and rear, the arms just don't look as parallel as I think they should be.
I'm going to take them back apart as I possibly got the arms swapped between the front and rears which may help the toe issue. But I thought I would get some thoughts from the forum as everything on what should have been simple on this bike has been a lot of rework. I need to readjust the cones on the rear axel, I think I forgot to grease the threads on the bottom bracket cups, and I have made two orders and forgot both times to add a chain to the orders.

You may have a bolt or two that could tighten.
I never have had positive results reassembling center pull. For me either the bushings fail or I couldn't get the pivot bolts right. To loose and backs out or to tight to pivot.

This was indeed the case. When I put them back together, it seemed easier to hook the springs and then tighten the pivot bolts. It turns out that with the springs hooked, it was not possible to correctly judge the tightness of the pivots. Unhooking the springs and tightening the pivot bolts got everything lined up nicely.
