85 Mercury Grand Marquis, Brake Fluid Loss
Q: I have an Ď85 Mercury Grand Marquis, great car but Iím losing brake fluid. The area around the master cylinder looks stained. Does it sound like the master cylinder needs replacing? If so what would it cost?....Ray

A: I would not recommend replacing the master cylinder without a thorough brake inspection. Why? Your vehicle is old enough to easily have problems with the hydraulic wheel cylinders for the rear brakes. The bottom line is, that when there is a braking system problem all 4 brakes should be inspected. Rarely is there danger in a vehicle that wonít start, but things can sure get interesting if a vehicle doesnít stop. Have your tech inspect the condition of the brakes at all 4 wheels then perform the needed repairs.
