94 F250 XLT 4X4 7.3L Turbo Diesel. 5 speed Stick.<O
</O
Having brake issues.<O</O
<O</O
Vacuum pump was bad, replaced it.<O</O
Fluid was bad so replaced Master cylinder, Rear wheel cylinders, Front caliper seals and Boots. Clean system.<O</O
<O</O
Peddle is not holding. Peddle bleeds down, pump it up gets great peddle, but then when it sits for a few minutes I have to pump it back up. <O</O
Peddle feels better when engine is off than when on.
¾” free play in peddle.
Where do I look now or do now.
PS<O</O
Just how does a proportioning valve work?<O</O
And what are the symptoms of a bad one?
