### ⭐⭐⭐ 







  
  
    Not a direct replacement
  

*by K***D on Reviewed in the United States 🇺🇸 on June 26, 2020*

It's not a "direct" replacement because the original master cylinder (#5130772) was a straight connect and this is a hollow bolt/ring connector. You will have to buy a new brake line with the right connector because the threads are different. Sooo... does "direct replacement" mean something different to this company?  Other than that feels good but I wish the brake lever was dipped in rubber.

### ⭐ 







  
  
    Didn't work for me
  

*by A***S on Reviewed in the United States 🇺🇸 on May 2, 2021*

Kind of worked the day it was installed. Brakes never got as hard as expected but it stopped.Went to use ATV 2 weeks later and had no brakes. No signs of fluid seepage and reservoir was still full.
