Dorman M73323 Brake Master Cylinder Compatible with Select Ford / Mercury Models

and other Ford models. The single Bowl Master Cylinder will cause you to lose your brakes if any wheel loses brakes. Line or Wheel Cylinder goes and you lose brakes on all four wheels... the double Bowl introduced in 1967 will give you at least brakes on front or the back, which ever system that does not fail as it has it's own section of the master cylinder "it's own Bowl".

Worked great no fit issues and used change kit

High quality, very nice casting, good fit and finish. I used this a custom retrofit on my 64 f100 and it works perfect.

Has Residual Pressure Valve. Contacted factory, but had to pull out the tube seat (with a #6 self tapping screw and a fat washer.) to find out, and to get it out. If you have Disk brakes on either circuit, you might want to pull the RPV (unless factory folks care to chime in) to keep brakes from dragging.

Was what I expected

The part fit perfectly, bleed easily, and provides great brake pedal feel. I used this in a four wheel drum 1960 Edsel along with a proper proportioning valve to replace a single master cylinder for safety purposes. Car stops as it should, and has a good original style appearance. Extremely happy with the quality.

Bought this for my 1970 Mustang with four drums. It was a direct replacement, had no leaks at all and was easy to bleed. I’d recommend it

Works great on my 68 Mustang.
