Rear brake on CB550F question about design

<< < (3/4) > >>

Seabeowner:
Brake pedal adjuster bolt hole is inboard of the main frame tubes. Short bent bit of meatal for 6mm bolt that bears on the back of the arm that the pulls the brake rod. The other arm on the this shaft with the hook is for the spring of the rear brake switch.

Ok, so something weird here.

When I took the bike apart, this screw was placed in that screw hole:

But when I try to refit it now, it seems the screw is too big, and is ruining the thread. See this picture. Don't know if it is just because of the powder coating, but it definitely seems as if the screw is way to big for the hole.

But I have a before picture of that screw in that exact hole! What do you guys think?

McCabe-Thiele (Ted):
If you are certain you  took that bolt out of the thread and it seemed normal then a tap down the thread should  remove any powder coating layer.

Oddjob:
TBH it looks like the bracket is bent out of shape, it should be flat and it should be threaded M6 x 1.00, that bolt could be UNF as it appears a bit coarser than standard.

Sesman:
Second oddjob comments. The plate should be flat eg perpendicular to the brake arm.
