So bought a 88 Lancer Shelby for a winter beater. Pedal goes all the way to the stop, left rear and right front wheels can still be spun by hand. Put new wheel cylinders and shoes on the rear yesterday, brake fluid is nice and clean with no bubbles. Do I have to replace the Prop valve? MC? All brakes seem to be bleeding fine but those 2 just don't work. Pedal goes to the stop no matter what. Need some guidance/advice/help. This was supposed to save my Shelby Lancer from winter driving and the snow is gone for the rest of the year now, it all went back east. If I can't get the brakes to work on this rusty canadian car I'll part it and scrap the body.
