    1984 ATC250R FULL KX85 brake Mod Part 1

    Ok so after reading every rear brake mod i could find i decided to document what i did for my restore. I apologize a head of time for the quality of this post. It's really my first one.


    1. I found out that any KX85 rear caliper from 2004 -2014 is a direct bolt on replacement for both your front and back caliper 83 or 84 atc250r!
    2. Also found out that I could simply just make my own bracket and use the front master cylinder from the same years as well!
    3. That makes it a Nissin brake system from the master to the caliper! Plus for around $85 you can get one as new as say 2010! That is what I did
    4. I then purchased a +2 Gafler stainless brake line for $33 on eBay brand new.
    5. The bracket in the pictures below is a prototype that is fully functioning. I intend to make a duplicate that looks nicer.



    FRONT MASTER MOUNTING BRACKET

    Step one:
    • Grind, cut, trace, drill & scratch head until i had the basic correct shape and mount points.
    • Buy two bushings to use as spacers
    • Buy two 1.5" M6 screws with washers and self locking nuts
