I purchased a replacement kit for brake lines.
It is 3/16 inch metal brake line replacement kit, 3/16" with 3/8" fittings. But the truck currently has larger diameter brake lines and fittings.


What should be used? My F6 doesn't have a booster. One line running to the rear, two lines running to the front off the master cylinder (which I also have purchase a new one).


I'm doing this because my master cylinder is leaking out of the front.


Thanx.

 

It appears you bought a kit for F-1's. F-6's use 1/4" lines. Did you buy a Parts CD? It would have saved you the trouble of ordering the wrong parts.

 

Parts CD, no. I have the shop manual and a typically search google.
Tried to get something cheap and should have know better

Thanx.

 

Ross is correct, they are 1/4" lines. Also when you change the brake hoses, make sure to save the adapters on the the end of the existing hoses.

 

Pic of 1948/52 F5 (T); F5 COE (W) & F6 (TH); F6 COE (WH) brake system from the 1948/56 Ford Truck Parts Catalog, available on a C/D from hipoparts.com

This is the catalog that Ross mentioned, but it does not include body parts for 1948/52. You would need a 1944/52 Ford Passenger Car & Truck Body Parts Catalog, that is not available on a C/D

It's reprinted (bound paper) by faxonautolit.com .. but it's half the size of the original and 75 bucks. Originals can be very hard to find.

 

Be sure to have the drums mic'd
The overbore on the front is .020" / rear .060

If they are over the above, thicker linings and radius grinding of the linings is recommended
