NO ,JUST NORMAL COLD STARTS . THE PEDAL IS HARD TO PUSH DOWN UNTIL IT WARMS UP THEN THE PEDAL WORKS LIKE POWER DRUMS SHOULD ,

OK, sorry Catmando, you did say power brakes.
:eek: To me it sounds like you are not geting the power
to the system. The brake booster is vacuum suspended and uses manifold vaccuum for its power. The only adjustment is the push-rod, so why the brakes dont work when cold I am not sure.
If you think the booster is working try the following conditions,
brake pedel linkage sticking, collapsed or leaking vacuum hose,leaking vaccuum chamber, or a leaking automatic transmission throttle vavle vaccuum line connection or fitting. If none of those prove to be the trouble maybe the power unit should be replaced.:cry:
