Re: Brakes - Wives Tales & Misconceptions
The below from a website discussing the GRANADA SWAP (FRT) -
Quote:
I think the writer is describing the PDV (PRESSURE DIFFERENTIAL VALVE) as FORD did not actually release a COMBINATION VALVE (an assembly consisting of two or more individual braking valves) until 1972. PDV, PPV and METERING were separate. As for the PDV, if one does not want or need the WARNING LAMP FEATURE, actual DISTRIBUTION BLOCKS are available for a neater appearance. While this particular tech write-up has a 2001 date, it is still online and should have been corrected (IMO of course).

Re: Brakes - Wives Tales & Misconceptions
- BRAKE PROPORTIONING VALVES - 1. If you have the deeply-rooted need to install your own adjustable proportioning valve, be advised that they should NEVER be installed if the factory unit is still in place. Proportioning valves in series with one another can do nasty, unpredictable things! 2. If you have the deeply-rooted need to install your own adjustable proportioning valve, be advised that they should NEVER be installed in-line to the front brakes. The effect would be to make your vehicle rear-biased before you could say “terminal over-steer.” Front brake line pressure should always be left alone – only the rear pressures should be considered for proportioning. 3. In all cases, the basic brake system balance needs to be close to optimized to start with. This is the only way that a proportioning valve can be effectively utilized. You should never assume that simply adding a proportioning valve will address all rear-bias conditions, as even the best proportioning valves must be well-matched to the target vehicle.

Re: Brakes - Wives Tales & Misconceptions
You're correct there.
BUT, after scarring the hell out of the piston, won't he be surprised when the other one pops out ...

Re: Brakes - Wives Tales & Misconceptions
I worked with a really good construction superintendent for years. The tool/caliper reminds me of his old line.

Re: Brakes - Wives Tales & Misconceptions
And what are the odds he didn't open the caliper bleed screws and allowed the old fluid to go back into the ABS PUMP?

Re: Brakes - Wives Tales & Misconceptions
If you think that was salty, watch this procedure. He begins @ 5 seconds on the video -
https://www.youtube.com/watch?v=wSqDP-pwj2s Now I don't know but this seems a little gnarly for me. On my personal ESCAPE, the pistons had to be rotated LH so a SPECIAL SERVICE TOOL was needed. I finally found the required adapter @ FORD of EUROPE and yes, it came from JOLLY 'OL ... That piston is on a ratchet. You mess that ratchet up (don't even mind gnarling the piston or cutting the dust boot) and there is no self-adj feature. You then have to buy a new caliper or have in your tool box specialty tools to rebuild the caliper and also purchase service parts ($$$). I used to see things like this on a daily basis. This is why I am so CDO (OCD in correct alphabetical order).

Re: Brakes - Wives Tales & Misconceptions
If you have the time (and have the interest), watch this video describing a COMBINATION VALVE and see if anything described is wrong (if anything is wrong) -

OK, there seems to be little interest but over 3500 hits.
Here is another discussion that should make you sit up straight - https://57fordsforever.com/smf/index.php?topic=9149.0

Re: Brakes - Wives Tales & Misconceptions
I don't have more than a basic caveman education on brakes. I will only work on my own. I will not work on anyone else's brakes period. From an 81-shop manual they have a slope chart covering all the fox platform cars for the combination valve. Since all of the cars use the same brakes with exception of the wagons. Seems though they concentrated on the amount of weight of the rear of the car. Some of the cars used different size rear wheel cylinders. 1/16th diameter difference does matter. Some of the cars used a different combination valve. My 95 truck and 91 Escort wagon had a brake valve hooked to rear suspension. I assumed it was a load sensing valve to hold off brakes empty and apply more pressure when loaded. When you start messing with brakes it takes a lot of experimentation. Dual master cylinders and hydro boost are not the end all cure all. Brakes are a science; I didn't do great in science. Figured Ford's glass house had lot more smarts and time than me. Yes, there is no emergency brake, always referred it to a parking brake in manuals.
