    I just received a new rear brake drum shoe kit for my 1982 XJ750RJ. I removed the old brake drum kit, cleaned up the inside of the wheel assembly, camshaft, etc. I got the yamaha brake drum shoe kit number from the yamaha website for my bike. When I tried to install it, the brake shoes would not fit inside the drum. I checked the part number on the container the shoes came in. It was correct. They look just like the shoes I removed but more brake material. Do you have to take some of the brake material off the shoe before you install them? I have never had to to this for car shoes. The Yamaha brake shoe kit part number was 3DR-W253E-00-00. Any suggestions would be appreciated.

    There should be no reason for having to remove any of the material from the new shoes.

    Check the following items.

    Correct Parts: Check the new brake shoes against the old. Make sure that the new shoes have the correct curvature, and mounting boses.

    Mounting Points: Check to make sure that the new shoes are seated properly on both the pivot pin, and the camshaft. Check to make sure that the shoes are not hanging up on the brake backer plate

    Operation: Check the camshaft lever to make sure that it moves freely, and is in the fully retracted position. You should feel the pressure of the springs as you try to move the camshaft lever. Tension bar mounting boss at the bottom. Camshaft lever point downward.

    The new shoes should be a snug fit inside the drum, but you should be able to turn the brake assembly inside the drum.

    Hope this helps

    I had a similiar problem with my rear drum. The rear drum apparently comes in two different sizes. I have the larger 200mm size ,which is probablywhat the shoes you got are (not that common) and the more normal ( ithink roughly 185mm size ) I believe the larger drum went to Oceaner, not Europe and the US.

    Sounds like someone swapped in a Maxim rear wheel what size tire are you running

    I checked the curvature, and mounting boses. They matched up to the old shoe except the pressed metal piece on the shoe that presses against the camshaft looked a little thicker than the original. I could not find any hangeup on the pivot pin, and the camshaft. The shoes are not hanging up on the brake backer plate, The shoes expand when the camshaft lever is moved. I looked at the marking on the shoe castings. They did not match. Old shoe had 5A8-00 and AK b120 GG. New shoes had 3DR-00 and AK L601 GG. The tire I have installed is a 120/90-18. The wheel has MT 2.16x18 stamped on it. I think they sent me the wrong part even though the part number on the bag matched what I had ordered. No way it will fit inside the drum without removing brake material. thanks for your help.

    Did not see that you had posted I no longer get email updates of posts have to fix that somehow Sounds like they sent you the wrong parts that is the right size wheel for your bike sometimes you will find where someone uses a maxim 16'' wheel it uses a smaller brake Good luck

    I know drum brakes have leading/trailing shoes, that are typically different sizes. Are both shoes the same size?

    I was wondering about that as well, is there a leading/trailing brake shoe on these bikes?

    I just changed my rear brake and it wouldnt fit as well at first. On mine there was a ridge left over along the rim of the drum from old brake dust. doesnt look like it would make a difference but when i was done they slid right in with no adjust ment to the shoes them selves.It needs to be ground off for the new brake shoes to fit. doesnt take too long I just took a dremel tool to it with sandpaper

    Nope; both rear shoes are identical. That's pretty much an automotive thing.

    I received a new shoe kit. Dropped it right in. Fits like a glove. Helps when they send you the correct parts. Thanks for all your answers.
