The stock junction-block will not affect the front brakes any differently than the disc proportioning-valve. The purpose of the valve is to control or reduce REAR wheel lock-up. I am using the stock junction-block on my '73 with front discs with no problems. If you ARE having a problem with the rear brakes locking-up, then a prop.-valve of some type will be necessary. Ford DID use a smaller outlet for the rear brake line on disc equipped cars...
: I can't give you all the answers, but I installed front manual discs on my 1970 from a 1980 Granada. I changed only the Master Cylinder. You must do this. The rear lines weren't bigger but the master cylinder had a larger reservoir. I didn't change the proportioning valve, and it stopped well. However, the front rotors were blue after about 2000 miles. They never warped, but I didn't change anything because at that time I changed to rear discs as well, solving the problem. Tell the board more information so we can help more.
: What year car?
: What disc setup? (Granada or Maverick)
: Was your car power brake before the swap?
: What Master cylinder?
: : Hi , I recently converted to manual front discs.I am not sure what I should do now because I have a hand adjustment propertional valve and it doesn't mate with the rear lines, and I have tried adapters but they all have a bigger inner pressure hole.Did Ford use a different dist. block for manual disc cars? What would happen if I just left this manual adjustment valve out and stuck with the drum dist. block?Oh , one more question, did disc brake cars come with a bigger rear brake line so it will have less pressure?
