Review on 🔧 Dorman M390337 Brake Master Cylinder - Brand New for Optimal Performance by Roshan Schram

I replaced my 1 1/16" master cylinder with this 1 1/4" everything fit perfectly and these were the best brakes I have ever had. Be sure to buy and use a bleed kit, it will take a long time to fully bleed the air. Great upgrade for my 1999 f150. liters of liquid and less than 2 hours of operation. If my 2003 F150 ever needs a new cylinder, I will choose it. Very little foot pressure is required, be very careful at first as this will increase your stopping power xxx. If you're pulling weight or hauling loads, I would look for a replacement. One kit manages pumping for all three ports. Use anti-seize compound or tape around the threads of the fitting when pumping. Hassle-free exchange.
