Review on 🔧 Dorman M390337 Brake Master Cylinder - Brand New for Optimal Performance by Jere Mosley

This Dorman unit was easy to install on my 1999 Ford F150. However, since I decided to flush the lines, it took some time to fully bleed the system. If you need to bleed a single person, I recommend Holt Industries #57057 Pneumatic Air Brake Bleed with Auto Fill Kit. This kit was very helpful and made it easy to bleed this master cylinder.
