• Q: How to service and repair the brake master cylinder on 2001 Ford E-250 Econoline?

  A: The brake master cylinder servicing process starts with taking it out of the vehicle before cleaning the exterior. Open the filler cap before draining all brake fluid from the system. Remove roll pins as a next step. Start the brake master cylinder reservoir service by gently lifting it up and taking out the attached rubber grommets. Service begins with unfastening the brake master cylinder fluid control valve along with its speed control deactivator switch and the accompanying snap ring before proceeding to the primary and secondary piston assembly. The brake master cylinder requires a new bore if it suffers damage so inspection and cleaning with isopropyl alcohol becomes necessary. Please lubricate the new piston assembly seals using High-Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or an equivalent fluid that matches Ford specification ESA-M6C25-A before installing the secondary piston assembly followed by the primary piston assembly and securing them with the snap ring. In addition to brake master cylinder fluid control valve installation you should add the speed control deactivator switch. Master brake master cylinder reservoir installation requires the use of new grommets which should be lubricated with the same brake fluid before being inserted into the master cylinder while connecting the fluid level warning switch. Pressurize the reservoir while inserting it into grommets until it locks into position after that install necessary roll pins. Tap the High-Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB along with equivalent fluid into the reservoir before placing back the brake master cylinder with its cap. To guarantee proper brake master cylinder function it needs bleeding as a final step.
