    Fixed my issue
  

*by J***7 on Reviewed in the United States on May 6, 2024*

Brakes were locking up due to a clog inside the master cylinder, this fixed it and now the brakes work perfectly. Installed on a 2001 silverado 3500 cab and chassis

    Installed easy and working great
  

*by K***S on Reviewed in the United States on April 9, 2021*

Literally took longer to bleed the brake system than to install the master cylinder.  It also has the monitor plug at the bottom just like the OEM, so everything lined up perfectly.  I assume the plug is to monitor the fluid level in the reservoir.I pre-bled using the Dorman 14151 Bleed Kit; this is the kit you want because it has TWO of each size plug.  I also needed a 15mm flare wrench to remove and reinstall the two bleed lines.  The 2 bolts that hold the master cylinder to the firewall were 15mm as well, so I used the wrench for both areas.
