Fishfiles 20,145 Posted October 17, 2022 Sent you the tracking number as a PM --------- he said you would get it in Wednesday ------ the one with the brake arm in the pic has a broken screw in the cover and the brake pivot cam was frozen , so I sent you the other one , much better condition , cam free and smooth , all the threads for cover in good shape , o-ring groove in good shape , sent you the cover also 2 2 Share this post Link to post Share on other sites

450S 15 Posted October 24, 2022 (edited) Well my rear brake backing plate problems persist. I finally got around to trying to replace the backing plate today but when I disassembled everything, I found that mine is quite different that the replacement one. On mine the brake shoes mount to two posts and the replacement backing plate does not have these posts, so the new brake shoes will not fit. Thinking I might just be able to find different brake shoes and still make the replacement backing plate work I continued trying to mount it to the axle housing, but I found that the bolt pattern is quite different between the two backing plates. I didn't waste time measuring the bearing sizes to see if they were the same. So it looks like this backing plate is off of some other year or more likely size than the 450. I am thinking I might just have to try and get the old backing plate welded up around the o-ring groove and see how well I can shape it with a dremel or a small cut-off wheel in a grinder. Anyone else ever have to do this? Any other ideas? Edited October 24, 2022 by 450S Share this post Link to post Share on other sites
jeepwm69 7,581 Posted October 24, 2022 Post a few pics of your rear end. The one without posts is, I believe, maybe a 300 backing plate. Share this post Link to post Share on other sites

Anyone else ever have to do this? Any other ideas? in the past, i have used jb weld on the backing plate to build up the area where the large o-ring sits in. then smoothed it down with my dremel tool. pretty easy to do. DO NOT TRY TO WELD ANYTHING TO THE BACKING PLATE !!..its not something that takes to welding. Share this post Link to post Share on other sites

Fishfiles 20,145 Posted October 24, 2022 Found one. Brake shoes and cam are froze up. Working on it. 3 Share this post Link to post Share on other sites
jeepwm69 7,581 Posted October 24, 2022 Good info here. I thought pretty much all the backing plates had the same bolt pattern where they attach, but in this thread we learn the 300 is different. If Fishfiles can't get you a good one, I can dig and see what I have in the stash. We won't leave you hanging. 3 Share this post Link to post Share on other sites

I am afraid it looks like water has been inside the housing, look at the last picture and see the rust on the shaft inside. Share this post Link to post Share on other sites

The bottom one is the original 2000 TRX450S, there is also a slight difference in the clocking angle of the cable mount. Share this post Link to post Share on other sites
