So I’m back putting some time into my R. Just installed my axle & going to mock up(needs a clean up before install) my brake caliper carrier. On my lonestar swing arm the brake caliper carrier goes over the bearing carrier & over a post on the swing arm but “rocks” up & down because of the space between the post @ caliper carrier. Is this normal or do I need to get the lonestar caliper mount bracket?

Brake stay bushing. 7.25 on ebay. Bdt has everything for the 250R🍻
Just bought new brake stay & bushing from BDT 👍🏼 I was going to “refresh” my brake stay but once I saw the price of new from BDT I wasn’t going to waste my time!

BDT to the rescue, Arrived in 2 days! And they sent me a cool carb tool with my order, Thank you BDT👍🏼👍🏼.

Now my only question is where this damn o-ring goes? Fits loosely where snap ring goes. Would it go between brake stay and carrier, between the snap ring & brake stay, not for my application? Wasn’t one on bike when I took apart....was missing a lot of little things when I bought it😁!

Answered my own question by looking at BDT website pics, o-ring goes inside the brake stay, there is a channel machined out for its placement.

Biggest pain in the butt that o-ring! I applied a little bit of red tacky grease to “hold” o-ring & seal for install.... super tough to get on, tried to “rock” on, tap on with rubber mallet....no dice! o-ring stuck on snap ring groove & it’s a wrap. No wonder the one I took off didn’t have one. Filled with grease & installed for now. Any tricks of the trade for this? I’d like to have the o-ring in there but it wasn’t happening for me tonight🤦‍♂️

I also just got this part, and was unable to use the O-ring either... I tried for about an hour, and finally the O-ring tore when it got hung up in the carrier groove.. Damnit!

If you can't install the o-ring on the bdt brake stay that means the o-ring gland isn't machined deep enough for the oem o-ring, also there's supposed to be 2 o-rings there. One that goes in the groove in the brake stay & one that goes on the carrier behind the brake stay. Without those o-rings in place if you ride in the sand than sand will get in there & make it hard to turn the carrier to make chain adjustments... Just out of curiosity what material is the bdt brake stay bushing made out of?

It's interesting isn't it, that some jump to blame BDT, without really knowing a thing about what they are talking about. I guess you can't change 'stupid'...!

The reason the o-ring can be hard to install for some is the variance in aftermarket carriers at the 70MM diameter....I have found some of these vary more than +.30MM in diameter and can make the o-ring difficult to install.

Also note we are not the only manufacture that sells Billet Aluminum Stays, however; we are the ONLY manucture that sells the stays with the o-ring gland machined in place, we are also the ONLY manufacture to include the Honda OEM o-ring....I guess if we take the analogy presented; they are ALL JUNK except the BDT Stay.

As an FYI; the BDT Rear Brake Stay, for ATC250R 86 & TRX250R 86-89 are made identical to the OEM Stay, O-ring Gland included. Both the Stay & Stay Bushing are made from 7075-T6 (go ahead scrappy and try to attack the choice of material if you dare)....will last a life time, guaranteed.

The additional o-ring mentioned, as well as the two o-rings that go on the OEM bearing carrier (note the aftermarket bearing carriers do not have the o-ring glands for these two o-rings) are also sold by BDT separately. I guess using the analogy mentioned by scrappy; all aftermarket carrier are than 'junk' since dirt & sand can get into the system...LOL

For any BDT customers that purchased the BDT stays, and are or had difficulty installing with o-ring in place; send me an email to: [email protected] and I will send you Two Honda o-rings and instructions on how to get these on without damage.
