The brake on my G was full of oil and grease so I took the brake off and brought it to the dealer who cleaned everything disassembled and reassembled it. Now, to get the drum on you have to back the adjusting bolt way off. When you try to adjust the brake it?s impossible to turn the adjusting bolt in anywhere close to where it should be. The petal then will push all the the way down without expanding the shoes. The top of the front shoe seems to be to high and won?t move down which seems to be the reason it can?t be adjusted. Did they assemble something wrong? Are the shoes reversed?
