On my 66 mustang, I did a CSRP power disc brake conversion.
I'm ready to road test my new motor and trans (331 stroker and 4r70w trans) install. But I've got a concern.
When I installed the csrp disc brake conversion, I power bleed the system (and I prebled the master cylinder) The pedal felt odd. Sometimes okay, a bit spongy but never "stiff".
When I first started the car, the pedal went to the floor, but you could pump it up. I figured I needed to bleed the system. Had a buddy come over and bled. It got better, but not great. Never stiff/solid. I thought maybe i had the bias too far when I bled it. So I backed off the proportioning valve to see if the bias was set wrong and rebled.
I have the car on Jack stands, so I wanted to give the brakes a test before setting it down. When I put the car in reverse, with the brake pedal applied the rear tires will spin. I can pump it up and try to press harder, but can't get them to stop spinning. Obviously, this isn't desirable for an auto trans so shifting from reverse to park while the wheels are spinning isnt good for the tranny.
I thought, maybe I don't have them adjusted properly, so I tried spinning the adjusters out a few. Im turning and turning and not really getting much difference in the pad bite. (Mind you, I'm a disc brake guy and have always dreaded drum brakes with an unrealistic fear)
Tried again, wheels will still spin when in gear and brakes applied. (But with the car off I could physically feel the pedal difference after adjusting the out). I tried turning the bias to rear even more knowing its not fully counter clockwise per csrp instructions. That didnt help.
So, I thought I might need to rebleed the rears, so I did that. Again, still the wheels would spin while in gear on Jack stands. I had the tires off at this point, and when I tried to use the brakes this time, the drum shot off the passenger side bouncing off the ground.
Can come one give this knucklehead some advice? What am I doing wrong here? What am i missing? I can't test drive without brake confidence. Am I just not adjusted out enough? I can slide the passenger drum on, but it takes a wiggle to get it off. Same on drivers.
