[FC] pulling to the left when braking 3....

[James Davis]

Having had a wheel cylinder leak on the right rear, I can tell you 
the Rampside would  violently turn right when the right rear 
grabbed.  A pair of Clark's wheel cylinders and #226 rear Porterfield 
RS-4 shoes cured the problem.  I used Praisedynobrake 33 lb spring 
set to make sure the shoes retract.
