thanks that helps alot.the underhood sticker appears to have been missing way before i got the truck.i was happy yesterday to have finally gotten a brake pedal on the truck.after a new master cylinder,3 brake hoses,2 wheel cylinders and all new lines to the rear from the master cylinder to find out that the rear load valve was bad.i bypassed it and have decent brakes now.i dd resurface the drums and rotors and replaced the 2 rear brake cables so at least the brakes are in good shape.
