one thing my bro found out was that a newer yz front caliper will bolt on the rear of a 250r with some slight dremel work.
plus you can use the yz rear master cly too and it is rock solid!
here is how i made the mount for the master cly

Ok I bought a YZ400 front caliper I believe, and when I went to put it on, the disc is too large to fit between the pads? How do I fix this? I don't know if you went through this or not..

Got the holeshot
Edit... First off...what YZ caliper are you talkign about. Can you give a more specific model and years of that model which will work? Im not too up to date with quads so that would really help me... Also, what is this slight dremel work needed to get the rear caliper on? Stock 250r Mounting bracket? Is it a dual or single piston caliper?
Nouse, use c claps to completely compress the pistons and give it another shot. If not, you may have to grind a little of the brake pad away to get it to fit.

Ok you were right. I didn't even look, but the pistons were out almost the whole way. I pushed them back in and it fit fine, but now the mounting plate for the caliper is too thick to allow it to fit between the disc and swingarm mount or whatever it is called. I can't get the mounting plate off of the caliper.. how do I do it?

the Mounting plate probably has apin that slides into the caliper. Maybe heat that pin up a little bit. What is the overall condition of the caliper? Looks kind of beat/rusty? If so, its probably frozen. Just heat it up or soak that pin with PB Blaster or your Favorite penetrating oil/aersol and give it a shot. Dont be afraid to give it a good tug to get that pin/bracket out. Just be really careful when using the heat ors.

i'm the brother of swigin.
i have a 98 yzf 400 front caliper on the back of my 86 trx 250r and you have to dremil out the holes more with this one. the caliper was spaced perfect i did not have to modify the yz bracket so you must have a stuck slider. i just egged out the hole and it bolted rite on.
the 2002 yz front calipers like we used on the 350rx you do not have to do it as much. any model yz will work 125 250 2 stroke or 250 450 4 stroke they are all the same.

Its a very nice caliper.. no rust at all and it looks almost new (with the exception of a tiny bit of dirt from use that will wash right off).. the mounting plate is just a little too thick. I'll get pics later.

since you have a 85 250r that mite be the problem since they have the different mounting system from 86-89 atc/trx250r'sOriginally Posted by nouseforaname90

heres some caliper pics
as you can see you dont need to slot the mounting holes much since no hole is showing under the allen bolts
and on some you need to grind a small amount off the mount under the rubber piece thats under the word nissin

There and by the mount hole in the front. Yours seems to be flat right there, and mine is not. I guess I'll just have to grind it down.

just a note, if you have an 85 r, you need an 86 r rear caliper mount to make this work.

The rear stainless line, is that for a 86 r or for the Yamaha application?
OPPPS-I see you used the whole set-up sorry, can you just use the caliper without the master by chance?
