Marv's Wagon 91 240+t Megasquirt

if you changed the proportioning valves... you might want to try bleeding it with the rear end jackup as high as possible...

Yeah that's what I am going to do next after I redid the bench bleed of my master cylinder last night. Was going to rebleed the brakes last night but ended up doing pizza and beer with my wife instead.
 
In my experience, once you get the get the bubbles out through the front calipers the official order [for a dual diagonal 240] to use the least amount of fluid is as follows,

1. Drivers side rear nipple
2. Drivers side front upper nipple
3. Passenger side front upper nipple
4. Passenger side rear nipple
5. Passenger side front outer lower nipple
6. Passenger side front inner nipple
7. Drivers side outer lower nipple
8. Drivers side front inner nipple

The cadillac brakes only have 1 bleed port on them and the new ATE rear calipers only have 1 bleed port on them also so I've been following a bleed procedure as if the car had ABS. Bleed the caliper that's farthest from the junction block first and work my way around until I'm bleeding the closest caliper.
 
I'm an idiot.

So yeah, as I was saying...

Turns out all I needed was a small rod coupling on the brake booster rod. The stock rod is too short to actuate the mustang master cylinder. Id probably bled a gallons worth of brake fluid through the brake system thinking i had the process wrong or that there was somehow still air in the brake system.

The stock rod on the booster is sae thread so I was able to find a sae to npt stud at my local ace hardware. So purchased a new stud and then a 3/4" length rod coupling gave me the needed length to actuate the master cylinder when I pressed on the pedal. Finally, a stiff brake pedal.

I spent yesterday evening playing with the rod length. It was too long at first so the brakes were dragging. That's one way to bed in the new pads i guess. But I was able to get it really dialed in.

Still dont have the parking brake hooked up. I'll **** with that another time when I have a day to waste.

Overall I'm extremely happy with how the brakes turned out. I nearly put myself through the windshield the first time I really stood on them. I've never used the red stuff pads before but so far they're great. No noise from them.

Looks great! Although this was a golden opportunity to ditch the proportioning valves altogether, especially in light of the now even more pronounced imbalance between front and rear braking power.
