Mercury Grand Marquis Brake Master Cylinder

The Brake Master Cylinder in Mercury Grand Marquis vehicles as a vital part of the brake system is in charge of translating the foot pressure applied by the driver into hydraulic pressure. This hydraulic pressure is then transmitted to the slave cylinder which results in movement of the brakes, so as to enable the vehicle come to a standstill. Conventional characteristics of the master cylinder include pistons, seals, and springs constructed in cast iron or aluminum while the container of the fluid can also be constructed within the master cylinder or can be external. Mercury Grand Marquis models for many years incorporated dual circuit master cylinders, so that even if a single circuit had to fail the other one would offer braking capabilities. This is proves to increase safety since the machine can continue to run in case of failure of the hydraulics. Some problems that might be encountered in the Brake Master Cylinder are leakage of the fluid and internal problems of the said component which would reduce the effectiveness of the brake system. Periodical check for signs of leakage and dampness is required since these could affect the functionality of the braking systems.

Q: How to overhaul the master cylinder on Mercury Grand Marquis?
A: In order to overhaul the brake master cylinder, consider whether you can get a new one at a reasonable price. Put some rags underneath the Brake Line fittings and cover up the line ends when you disconnect them. Use a flare-nut wrench to unscrew the tube nuts, plug up their ends and also disconnect the brake warning light connector. Take off the mounting nuts and separate the brake master cylinder from it. Remove the reservoir cap and use a brake system cleaner to clean both it and the cylinder. Replace if necessary by examining for damage in bore. Then grease new reservoir grommets and push them into cylinder body. Grease bore and piston assemblies, and press body onto the reservoir. Insert piston assemblies, then snap ring should be installed before capping is attached on top of the diaphragm that may need changing if damaged. To do bench bleed, fill both reservoirs with fluid as well as place plugs to expel air from those fittings.
