Two brake caliper dust seals and two piston seals to replace 45109-MA7-006 and 45209-MA7-006 for the rear brake caliper of 83 GL1100, GL1200, GL1500 and other Honda models. These seals are about 37mm in diameter.
NOTE: According to Honda, the two front brake calipers of the 83 GL1100 should be the same size. But some owners discover that one front caliper is the same size as the rear. In that case, these dust and piston seals could fit the front brake caliper of 83 GL1100.
