Re: CPP Rear Disc Brakes not bleeding!!
Seriously... did you replace the rubber line from frame to axel yet? I speak from experience....

What do you mean 'no brakes'?
|
Re: CPP Rear Disc Brakes not bleeding!!
I put Cadillac disc brakes on the rear of my 55 Chevy.
I had to move the pushrod up 1" on the pedal to get brakes. |

I bled the entire system again with my wifes help. The old 2 person pump method. She said the pedal didnt go to the floor when bleeding the back. So its not building pressure |

So it makes me think the pedal location is correct. |

Re: CPP Rear Disc Brakes not bleeding!!
Moving that rod is just going to increase or decrease pedal pressure required to stop.
Are you sure the valve is adjusted so that you are getting pressure to the rear? Maybe it's dialed all the way to the front? |
Re: CPP Rear Disc Brakes not bleeding!!
At this point I am inclined to think it is the proportion valve as well. Do you have a way of measuring the pressure? Line pressures can get pretty high. Well over 500lbs when you press with authority. It may be worth buying a brake pressure gauge. I have 1 on each circuit for the race car. It was very helpful with adjusting the bias initially but didn't use them much once I got the feel of the car and sorted what pads to use. Just get a cheepo brake gauge and set it up at the caliper. Then fiddle with the proportioning valve. I recall you having a manual type. If you are using the factory type button reset valve, I assume you have reset it.

None of which worked. |
Re: CPP Rear Disc Brakes not bleeding!!
"She said the pedal didnt go to the floor when bleeding the back."
So, she pumped up the pedal a couple times and held it. You then loosened the bleeder. Right? Did you get fluid out? Lots? little? Did you then tighten the bleeder, without the pedal going down? I'm pretty sure from your pictures, you have this right and with the parking brake I think it would be hard to mess up. Do you have the bleed screws UP on the caliper? They are not facing down? It would be calipers swapped side to side on the truck. |

Bubbles came out out first, but then a steady fluid stream, just like its suppose to. The bleeders are facing towards the front. |
Re: CPP Rear Disc Brakes not bleeding!!
Any ideas on how to attach a power bleeder to a willwood master cylinder?
|
Re: CPP Rear Disc Brakes not bleeding!!
If you are getting fluid at some decent pressure, is the pad contacting the rotor? With your foot off the brake, the pad should still be hitting the rotor a very small amount. Not actual drag on the rotor, but if you spin it, you can hear it hit.

Any ideas??? |
Re: CPP Rear Disc Brakes not bleeding!!
All the heart ache you have gone through, man I feel for you! I would figure out how to adapt a 2000 psi gauge to a rear caliper line and see what kind of pressures you are getting. This would at minimum tell you if you are getting any pressure to the rear. Then you can see if it’s a caliper problem or upstream.

I purchased a Motive power bleeder and was hoping that I could attach it to the wildwood master. The people that have felt the pedal and have seen it tell me it feels like I have air in the line. So I want to power bleed to help process of elimination. |

At this stage, you might want to consider taking it to a shop. |

I was just rereading this thread . Yours are positioned just like mine on my Chevelle . And just realized that when I bleed my rears I had to remove the front bolt and spin the caliper up I put a piece of plate steel in between the pads . As the bleeder is below the top of caliper . The bleeder needs to point straight up .
I copied your picture . If you look at it it’s pretty clear the bleeder is about midline in relation to the piston . After I did the one I rotated the bracket so the bleeders point straight up so in the future I didn’t have a problem |
