You could be at the point where your brake pads are degassing enough to require slotted rotors, or better pads.

Worn out master cylinder can lose pressure that comes back if you release and re-engage (pump it).

If it ONLY happens when the brakes have been given some serious heat, try better pads and/or slotted rotors.

You don't need new rotors but I won't say you shouldn't try to convince your wife lol. Try bleeding the brake system and replacing the fluid.

WHOA WHOA WHOA.....


NEED slotted rotors to repair a car? NO you do not. You might need new rotors, but you can re-install factory designed parts from your local parts store and that will be just fine. Slotted and/or cross drilled rotors are a performance part designed from racing. The slots provide more bite when braking, and the cross drilling provides more air flow to cool the pads. I can understand why an 00-04 owner might need those to improve the weak brakes Ford installed on those, but in 05 the brakes were upgraded. It was the same design as the SVT, except about 1" less in diameter on the front.

For factory parts, I prefer O'Reilleys if you have one. They sell lifetime warranty rotors and pads from Wagner. Change them once only. Ford stuff is well worth the money also. I have gone close to 90k miles on my last Motorcraft rotor and pads. I have a friend who runs a courier service, he swears by Motorcraft brakes.

Now back to your problem- it sounds like you have contaminated fluid- most likely contaminated with air, but it could be moisture. You should first check your brake fluid reservoir cap to make sure it is tight, if it is, then loosen it and look at the rubber seal under the cap. If it's deformed beyond recognition, then you need a new cap, and you should probably have the fluid drained and replaced. If all is good there, the seal is not horribly deformed, then I would simply bleed the brakes first. Try not to add fluid- fluid level is affected by how much pad is left. When you change the pads and rotors, you'll fill it back up to max, when those wear out, the fluid will be low.

You got air in the system buddy. Bleed the break system and you should be fine. Don't buy new performance rotors, in this case you don't need them, the bleeding will cost you maybe $15 for two bottles of DOT3-4 and 1.5 hours of work, and you'll save the money to buy some for the wife lol!!!
