Replacing Master Cylinder
I have a 1979 bronco which needs a new master cylinder.
Someone told me that the ones off a 350 on a certain year i believe will bolt onto the 79 bronco as well.
Does anyone know if this is true or not or which 350 it is so i can get the specs and pick one up.
What would the advantage be of getting one from a 350.
Thankyou.

Replacing Master Cylinder
[updated:LAST EDITED ON 23-Nov-02 AT 10:11 AM (EST)]There's a tech article on this..... it's on the FTE web site. This may be an upgrade for the '78 and '79's (yes, the F350 m/c should bolt up). I was a fan of this and was ready to make the swap on my '85 until I did some extensive research on it (by digging through the Raybestos catalog for a half-hour!). I found that many of the '80 thru '86 F150's and Bronco's actually used the same m/c as the F250 and F350's of the same years, though some had a different booster. Where there was a difference, the F350 m/c's were spec'd with larger bore diameters, as would be expected in the heaviest duty models. While these would bolt up, the effect of having the larger bore diameter (with nothing else changed.... calipers, lines, etc.) would have made your pedal effort easier, but would have reduced the line pressure and, thus, the effective clamping force, or force pushing the brake pads and shoes against the rotors and drums. This is explained in the article. It's worth reading, and may change your mind. Here's the site: https://www.ford-trucks.com/articles/oct2001/brakeupgrade.php
