Dear all,

I'd like to ask you some info concerning the Brake master cylinder: is there a master cylinder interchangeable with the original one (F/91A-2140) that could be bought in the after market / internet?

If yes, could you please provide me the brand and / or the part number?

thanks a lot for the help and kindness.

Kindest Regards

Luigi

In both SB-8 and SB-8A the body description has the fender brackets being riveted to the fender and bolted to the body.

The pictures in the manual show rivets whereas my trailer has bolts.

Another difference is a change of master cylinder. SB-8 in the parts listing has a part # of 91A-2140. This is a master cylinder with a 1-1/6" bore for a Ford 1/2 ton pickup. Whereas my trailer has the larger cylinder with a 1-1/4" bore for a Ford 1-2 ton truck. Looking over the picturs in the manual you can make out a difference in the reservoir height between the 1/2 ton and 1-2 ton master cylinder. So obviously both were used but only the small is listed.

Lastly a bit of a mystery item that doesn't show up in the parts listing or the wiring diagram. An extra side mounted tail/stop light. This was in the SB-8A manual only.
