Dynamic Friction Company Brake Master Cylinder P/N:355-01008
Dynamic Friction 355-54141 brake master cylinder for the 1977-1979 Ford F-250 and other vehicles turns pedal force into hydraulic pressure for the brakes.
A pedal that sinks slowly, brake fluid around the cylinder or a brake warning light can mean a master cylinder is wearing out. These signs alone do not prove it is the problem, since a leaking brake hose can also let the pedal sink. If the master cylinder is the cause, this one replaces it.
It fits the 1977-1979 Ford F-250, the 1977-1985 Ford E-250 Econoline and the 1979 Ford F-350. A 1977-1979 Ford F-250 takes one.
Is this a Ford F-250 brake master cylinder for the 1977-1979 model years?
Yes. Dynamic Friction 355-54141 fits the 1977-1979 Ford F-250, and the 1977-1985 Ford E-250 Econoline is listed too.
Does this Dynamic Friction brake master cylinder come with a reservoir?
Yes. The Dynamic Friction 355-54141 master cylinder includes its reservoir.
What bore size does this master cylinder have?
The bore is 1 1/16 inch. That is the measurement to compare when matching it against another master cylinder.
Could a brake pedal that slowly sinks be a master cylinder problem?
It can be. Worn internal seals in a master cylinder can let the pedal sink, so have the brakes checked promptly, since this is a safety system.
Will this master cylinder work on the 1979 Ford F-350?
Yes. Dynamic Friction 355-54141 is listed for the 1979 Ford F-350, and that truck takes one.
