Re: Brake Problems: What Could It Be?
Hi James,
You want the smallest master cylinder piston you can find, and the
largest front slave cylinders you can find, to multiply your pedal
leverage.
Hi James,
Double check someone didn't put your brake shoes on backwards, the
short shoe should face the front.
The proportioning valve should be centered if the brake light isn't
lit. To test have someone push the brake pedal while you bleed an axle,
quickly, the light should light, then slowly bleed the other axle until
your helper tells you the light went out, very touchy.
Know that especially with power brakes, tires above 34" will not
lock up on pavement, but will stop you as fast as feathering stock
tires.

The proportioning valve acts as an emergency cut-off should the
front or rear brake lines spring a leak. Taking the guts out is
dangerous.

The booster replaces standing on the brake and adds significantly
to the available hydraulic pressure.

That is why when adding a booster to a standard system you have to
upgrade the flex lines and double check all hard lines. I installed
one on a friends pickup and the first time he tested it, it blew a
bubble in the flex lines.

Re: Brake Problems: What Could It Be?
Okay Doug, you're right. I knew better than that when I started typing.
What the hell am I thinkin', "gut a brake part"?! Anyway, I knew about the
axle-loss safety feature (just brain-farted), but doesn't the PV bias
pressure so the rear doesn't lock as easily?

Re: Brake Problems: What Could It Be?
You're driving on front drum brakes with a foot that is used to disks.
Drums were always weak, and worse when wet. You should consider
converting the front to disks -- find a donor axle and it should be a
bolt-up job.
