shadetree 5,977 Posted May 16, 2021 Ok outlaws, most of ya'll know that i am well into old school trx350's. sooo, after fighting all the time with my front brakes on my '89 trx350D foreman, i decided to do some trial and error with her. i only buy highlifter front brake kits for my personal toys. as too which i already have on my '03 trx450fm. we all know ( or you should know ! ) that the old trx350's call for 11 inch rims, and front disk brake kits require 12 inch rims. on top of this, i know i had to see if the mounting plate for the brake caliper would bolt to my 350 knuckle ?, sooo..i pulled my 350 into my shop, pulled my 450 out to jack it up, got both front left wheels and hubs all the way off. first, what does the 25x8x12 tires look like on the 350, will i have enough room to clear my front fender, and not hit when turning ?, as you can see in the pic's below, 25x8x12 tires WILL clear without a lift !. next: does the mounting plate line up with the 350 knuckles to bolt on ?, again, as you can see..the plate DOES line up 100% !. last but not least, i took my 450 hub, disk set-up, and it fits right onto the 350 front axle !!, bearing, seals, splines..all go hand in hand !. my mail man is going to give me the brand new steel 12 inch rims off his 500 i sold him, i will have to buy new itp mudlite tires, and a highlifter front brake kit for a trx450fm foreman, but..I KNOW IT WILL WORK !.i will keep this thread updated when as i make progress !. i may have to '' tweak '' the bend in the mounting plate to center the brake caliper ?, i wont know this yet until i get the brake kit. folks, THIS IS GROUND BRAKING !!..NO ONE ..NOT EVEN ME !, HAS EVER TRIED TO PUT DISK BRAKES ON AN OLD 350 FOURTRX THAT I KNOW OF ?...THIS WILL BE A FIRST , ONE OF A KIND THAT I KNOW OF !?!. 7 2 Share this post Link to post Share on other sites

CamKnouff 148 Posted May 17, 2021 (edited) Any idea of the cost of this, without a great mail man? I just ordered 2 Mudlites 25-8-12, $219 delivered Royal Distributing . Up here used parts are a little hard to find at a decent price. I know it will sound cheap in US dollars. lol. I think my 2 350's will out last my 2019 Rubicon, All 3 should outlast me.

shadetree 5,977 Posted May 17, 2021 just a small tad of info for all that keep wondering how to mount a winch plate to these models. 3/16 steel plate, pre-drilled winch holes, cut out the plastic grill and the side inner guards, presto, plate welded to tube frame. i have a better front fender that i will swap over onto this girl, took the rest of the night off, i'm beat. 4 Share this post Link to post Share on other sites
Wheeler 2,530 Posted May 17, 2021 Sweet! One thing I noticed... you like myself ha e installed the disc backwards! Not that it really matters, as it will work the same. Congrats. 1 Share this post Link to post Share on other sites

Congrats. there is no RIGHT WAY OR WRONG WAY to install the rotors. it makes no difference which way you face the rotors, they will do the same job no matter which way you have the slots facing. i did not read anywhere in the instructions where it said the disk had to face a certain way ?. and even if i missed it ?, oh well, not gonna reverse them, they still stop on a dime !..lol. 2 Share this post Link to post Share on other sites

jeepwm69 7,751 Posted May 17, 2021 @Mac102004 has done this I believe. Required shimming the caliper bracket but it does work. Do a write up @shadetree! Lots of pics! While I've seen people say they've done it, nobody has done a write up on it. Would be another great sticky here! 3 Share this post Link to post Share on other sites

While I've seen people say they've done it, nobody has done a write up on it. Would be another great sticky here! never seen mac post about it ?. what is the reason for shimming the bracket ?. like i told fish on the phone, no reason to shim ( washers on bracket ) caliper , as the plate has two bends to it, both can be bent on my press to center caliper to rotor disk. waiting on my mail man to drop off the steel rims, I WANT TO BE SURE THEY CLEAR ALL AROUND !, before i start buying tires and brake kit. i deff will post progress pic's as this mod moves along. 2 Share this post Link to post Share on other sites
jeepwm69 7,751 Posted May 17, 2021 I'm guessing whoever did the project before used shims instead of bending the brackets. WIthout shims would be better, so post pics as you go! 2 Share this post Link to post Share on other sites

Fishfiles 20,147 Posted May 18, 2021 De'Ja'Vue , check this thread out : the pic links to the SuperATV kit on the 350D have since expired , that was back in 2012 , maybe Lancer77 has some pics saved , I remember him Reading the end of this thread I realized one of my unfinished brake projects , rear brakes on the rear of a TRX250 Fourtrax/Big Red rear end , I got all the stuff in a gang box , all I needed to do to finish was weld the new flange onto the axle tube --- https://www.hondaatvforums.net/threads/87-foreman-350-brake-and-shock-swap.19600/ 3 Share this post Link to post Share on other sites
Fishfiles 20,147 Posted May 18, 2021 Looks like he stuck 4 maybe 5 washers between the caliper and the plate , I think you would have a hard time bending that bracket that much and keeping it in line cause as you bend it over it is going to drop down ----on part of the situation was very similar when I did the 300 2wd , I had to make a new mounting plate as the mounting hole pattern was different , but at the same time I made a new mounting plate that was straight with no offset to eliminate any need for spacers and that looks much like where you would need to be , imagine no spacers and it looks like it would line up nicely ---as I mentioned , I used shims behind my hubs to fine tune the disc in the caliper , I needed 1/16 of an inch , if I could have got 5/16 plate , I would not have needed any shims according to the automotive world , those disc are on backwards as @Wheeler mentioned--- those slots or holes for cooling purposes , doubt that 350D is going to go fast enough to have that problem 2 Share this post Link to post Share on other sites
Fishfiles 20,147 Posted May 18, 2021 Looking at that pic , the caliper is cocked as the pads are hitting top heavy , also see that the inside edge of the mount bracket would be in pretty close alignment with the caliper's mounting surface , then no spacers would be needed and it might take that cock out of it Share this post Link to post Share on other sites
shadetree 5,977 Posted May 18, 2021 update: ok, after talking to fish, and telling him my game plan after his plan, i came up with a much better idea. instead of spacing the caliper out with washers ( i did not like that idea at all ! ) i decided it would be much better to put some 1/4 steel flat bar behind the mounting plate. as you can see in the pics, it came out great so far !. i only got one spacer made for now to fit behind the mounting plate. the pic's show ( and from what i see in person ) that this will work out great !. i will have to get longer bolts to attach the mounting plate and spacer to the knuckle ?, but that should be easy to do. anyway, still waiting on my mail man to bring me the 12 inch rims. got to get all my spacers made before i put the kit back on my 450. i will keep posting updates as this mod moves along, stay tuned outlaws !!. 5 Share this post Link to post Share on other sites
