Matador Brake Questions

[Todd Tomason <jayscore@xxxxxxxxxxxxx>]

When the local tire shop fixed a flat yesterday they said the brake caliper 
seemed to be grabbing.  My first thought was to just replace the caliper, but 
now I'm not so sure.  We checked both front wheels when got home and both 
seem very stiff.  You had to grab the tire with both hand to get it to move 
at all.  Could this be a bad master cylinder instead?  Is there anything else 
I should be checking?  BTW, this is a 78 with front discs and rear drums.  

Thanks,


Todd
