I re bled the brakes last night

with same result of low pedal.  I have a 2000 V6 disc brake master cylinder.  Waiting for my sons project in the attic...LOL  Debating on using it or not?  I currently had a ford ranger master cylinder disc/ drum.   I have a Granada distribution block with a rear adjustable proportioning valve . I had thought I seen a previous post about gutting the Granada distribution block so it will flow to all 4 wheels instead of 80/20 split that is used for Disc/Drum brakes.  Trying to avoid  changing all my brake lines under the hood.     I also pumped the emergency brake pedal at least 50 times.  Thanks for the help!

Re: I re bled the brakes last night

 Are you sure the M/C has been properly bench bled? It's worth a try......

Re: I re bled the brakes last night

Ok, I see at least part of your problem.

You have TWO proportioning valves in the system. 

You have a Granada combination valve that has a proportioning valve built into it.  Then you added an adjustable proportioning valve.  No way will you get enough pressure to actuate the rear brakes.  If you gutted the Granada proportioning valve, did you remove ONLY the proportioning valve function or also remove the differential pressure valve as well?

Remove the adjustable valve if you have disc/drum system.  Leave the Granada combi valve in place.  Be sure rear brakes are adjusted properly.

Remove the Granada block if you have disc/disc system.  Leave the adjustable valve in the rear line.  Be sure the rear brakes have the parking brake operational and exercise it sufficiently to remove any slack in the rear caliper pistons.

Do that, re-bleed the system, and it should work fine.

I never removed anything from the Granada block.  I had 4 wheel drums originally and when I added Granada disc to the front only 18 years ago . I added the Granada Block along with adjustable valve in the rear line.  

I do have the 2014 Mustang GT calipers on the front and 2019 GT calipers on the rear.  If I take all the guts out of the Granada block and keep the adjustable valve will that accomplish what I need?  I think it will since the block would be free flowing. 

Thanks Steve69

Re: I re bled the brakes last night

For what it's worth - I have disc/disc and a 2004 V-6 master cylinder. I used the distribution block out of a 95 GT and it works fine.

  Does the 95 GT have disc brakes on all 4 wheels?   Thanks for the info!

    Ill try taking the guts out of the Granada Block and see what happens.

Then maybe onto Disc/Disc MC.   I remember having issues with clearance with the ranger MC hitting the shock tower.  So I want to try to avoid that.  I don't want to get under the dash and loosen up the booster to make room to remove it.  Thanks for the Help!
