I was just going to swap my 71 over to everything 76-77, and then add the rear Crown Vic brakes. What you are saying about the proportioning block makes sense, but if you had the disc block with disc lines, running to a disc master, like you have, at least the plumbing would all fit without having to change fittings--that's all I was getting at. RightStuffDetailing's website isn't overly user-friendly, and I still have a few questions with regards to some of their products. If Micah said they worked with him to make lines with custom fittings, then I would certainly consider pursuing that. Is the block downstream of your factory block an adjustable proportioning valve, or is it a residual pressure valve (most likely 2psi)? This thread is full of lots of good info! And BTW, I agree with Tom (Krazy Comet) that your lines are the nicest looking rat's nest I've ever seen!
Yeah I thought mine looked pretty good till I saw those, but I'm not going for full blown show car... Somewhat related... On the copper washer, I had a leak at left caliper that loosening and re-tightening a couple times didn't fix(didn't want to remove, replace then re-bleed brakes)... Finally I smacked the banjo bolt with a hammer and iron bar, re-tightened and hasn't leaked since... No probably can't do same on the dist block...
SCS, I went with the disk/drum master and a disk/drum propotioning. With the lines Right Stuff made, you would not know it did not originally come that way. Nice, clean, correct. I was assuming you switched over also. I personally would avoid trying to adapt the old parts and install what should be there. Micah
To answer your question, I have an adjustable proportioning valve on the rear line that was supplied with my CSRP disk conversion. I have yet to deal with that, but I think it will be easy to adjust and get where I want.
OK, I'm summing up what I learned from everyone: Below is a summary of standard brake line fittings today Tube Size
Try that again, a Tab submits the thread! Below is what I have learned about US brake line sizes: Tube Size......Hex Size......Standard Nut Threads.......Nonstandard Nut Threads 3/16"----------3/8" -------- 3/8-24 ----------------------None 1/4"----------- 7/16"-------- 7/16-24 ---------------------7/16-20 5/16"----------1/2"----------1/2-20-----------------------None None----------9/16"---------9/16-18------------------9/16-20 3/8"-----------5/8" ----------5/8-18-----------------------None I have the Maverick bastard size marked (9/16-18). You can see why adaptor fittings are hard to find because it is not typically used on any standard tube sizes. Paul Masson has a good post above relating to what all the stock Master Cylinder outlet sizes are (and I'm sure there are exceptions!) Thanks for all the info.
I want to add that I did find the bastard fitting at a Brakequip dealer for my new master cylinder lines. A 9/16-18 female to 3/8-24 male (P/N BQ261). They also make a few 9/16-18 adapters in the "other direction". Thanks to whoever pointed me to Brakequip.
It isn't just Maverick, ALL Fords have some weird fitting size that are generally different by brake type, vehicle etc, I suppose it's to prevent installing the incorrect M/C... I'm sure more than one aftermarket vendor cussed Ford a new one over their fittings...
