Double pump brakes
I have been having brake issues since swapping out to an 8 3/4.
I reused the old drums (over the cut limit) and new shoes. the arcs are very different. It will take a lot on miles till the pads ware into the drums.
I changed the cyls at the same time.
I thought I had bleed the brakes enough, not by a long shot!
I ended up putting a pint of fluid through the lines and now have a firm pedal, but the braking effort is slightly greater due to the arcs of the drum / shoes
Bleed baby bleed
