[Vintage-race] Check valves in brake lines

[Craig Wright]

The check valve should go in the rear brake line. The front brake piston 
barely move, but the rears move quite a bit contributing to larger pedal 
travel. I think the valve for drum brakes is a 10 psi check valve. But 
check with someone more certain than I before buying it. Also ensure 
that the rear brakes are adjusted properly. The self adjustment never 
seem to get them tight enough for racing and they require manual 
adjustment before and sometime during each race weekend. Also check for 
warped rotors. If they are warped or have a runout issue they will knock 
back the pistons into the calipers as the wheel rotates.
