2001 Ford Excursion Brake Master Cylinder Parts Questions & Experts Answers

• Q: How to service and repair the brake master cylinder on 2001 Ford Excursion?

  A: The first step when repairing the brake master cylinder includes extracting it from the vehicle. Drain the brake fluid from the filler cap after performing exterior cleaning of the component. Before proceeding detach any brake pressure switch that applies. The first step is to depress the primary piston assembly which enables removal of its snap ring thus discarding this assembly. The service of the secondary piston assembly begins with plugging the rear outlet port and potentially the brake pressure switch port before inserting compressed air into the front outlet port for assembly disposal. The brake master cylinder bore requires inspection because damage requires replacement of the entire component. The bore must receive a cleaning treatment with isopropyl alcohol solution. Prepare the new piston assembly seals for installation through lubrication with High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ- t9542-AB or an equivalent fluid that matches Ford specification ESA-M6C25-A. Insert the secondary piston assembly first and then carefully add the primary piston assembly while executing the snap ring installation by depressing the primary piston first. At the end of the procedure replace both the pressure switch if present and install the brake master cylinder into its original place.
