I'm assembling my 9-inch Girling rear drum brakes after cleaning, painting
and replacing most components. I could use help on a few questions:
1. I painted both sides of the brake backplate with POR-15. I had planned
to just replace the original shims between the hub/backplate and rear axle,
but with new paint on both sides of the brake backplate, I'm wondering if it
will affect the required shim thickness. The backplate was painted black in
this area when I removed it, but the POR-15 is decidedly thicker stuff than
what
I found and removed. Any worries here, or is the paint a non-issue?
2. I understand the wheel cylinder is supposed to slide in the slot in the
brake backplate, but in my judgement it's a pretty snug fit when the spring
clips are attached. Again, I'm wondering if the POR-15 paint's thickness is
affecting the sliding action. How easily should the wheel cylinder slide in
the
slot?
3. Lastly, I replaced the return springs on the brake shoes. My manual
shows both springs fitting under the brake shoes, but when I disassembled my
brakes, the spring on the adjuster side was on top of the shoes. Which is
correct?
Many thanks for help on this. It's great to finally be reassembling things!
