Front disc brake conversion

ELECTRONIC ENGINEER? NAVY MOS?​

Now did you convert to front disc with the booster upgrade or did you leave the car drum/drum?

So just mounting and aligning booster on the firewall worked for you?

OH!

And how did you connect the booster push rod to the TREADLE-VAC linkage (hardware)?

Inquiring mind want to know ... :D

You're making my brain hurt trying to remember the details..:<)...the picture of the booster is what I ended up hooking to the stock linkage under the dash. I do not recall the actual fastener I used to connect the push rod to the pedal linkage. Nope, stayed with the drum/drum. The brakes were Mercury/Lincoln, 5 X 5 and self adjusting. The main issue with later boosters is the mounting bracket/spacing as best I can figure.

I say "electronic engineer" because of the training uncle sugar gave me. I was an electronic technician, trained in component level repair of radar, communication and computer systems. An advance course of electronic theory and design was offered to those of us (ETs) for a six year re-enlistment. The course was 52 weeks long, theory was taught 8 hours, five days a week with some night classes as well. It started with 1 + 1 = 2 all the way threw to calculus expansion. After that the theory part involved who, what and where components did to current flow, electromagnetic wave flow, propagation of RF energy and then finally circuit design. Very exhausting course! Gone now due to the digital age. Component level repair is mostly dead as well, most all repairs are module replacement with depot level module repair. Started as an E-1 and retired nearly 30 years later as a CWO-4 Electech.

You are first that is mechanically inclined having an actual EDSEL that I can pull info from. Too damn cheap to buy an EDSEL WSM/MPC. Sorry for the inconvenience.

So the EDSEL put MERC self-adjusting drum brakes on the wagon version also, along with TREADLE-VAC?

And the drums work well with the DISC/DRUM MC and PROPORTIONING VALVE? You decided not to go with a DUAL RSVR DRUM/DRUM MC at the time?

You're OK. Just wondering how you were able to do a mostly easy install without having to modify the TREADLE-VAC pedal linkage.

You have answered many questions and I appreciate your time.

One more question while I am thinking of it. Did EDSEL put the parking brake ratchet on the floor (foot operated) on the wagon?

As for the MOS info, appreciated. Heard a lot of info as to having to re-enlist for longer periods with selected advanced training.

Stand easy, take a break, drop your pack and smoke 'em if you got them ...

I found the brake shoes were Merc/Lincon when rebuilding them. The car Was a Pacer 2dr, ht. Yes, the emergency brake on the Pacer was foot operated, do not know if it was as such on the wagons....the master for the 65 Bird was a single pot, single outlet (two ports fed from the same source in the casting), the output in a Bird fed a junction block splitting the front line from the rear just like any single pot system. The rear line had the proportioning valve in it. My Edsel....

!!! THANX AGAIN !!!​

I think I have the basic idea now and will leave you be ...

Made a bracket to mount a dual 7" booster to the original treadle-vac mount and was back in happy land. The master was a 65 Bird. The original brake assembly worked just fine.

- A NOTE ON THE SGL RSVR DUAL OUTLET 1965/66 MC -​

This design MC was released for the first model year of a DISC/DRUM car (1965). It included a larger SGL fluid reservoir to provide the needed increased fluid volume to operate the front calipers.

The DUAL RESERVOIR MC was as a result of a FEDERAL MANDATE for the 1967 model year to provide increased safety for hydraulic braking systems by separating the front and rear hydraulic circuits. If one circuit fails, hopefully the remaining circuit will stop the car safely.

The SGL RESERVOIR DUAL OUTLET DESIGN does not separate the hydraulic braking circuits as does a DUAL RESERVOIR design.

The DISC OUTLET (SGL RSVR) will not have a RESIDUAL PRESSURE VALVE needed for a FRONT DRUM circuit. If the PROPORTIONING VALVE (DISC/DRUM - 1965/66 K-H 4-PISTON CALIPER setup) is used on the rear circuit of a DRUM/DRUM car, it may upset vehicle braking bias during a hard stop.

Not to ruffle any feathers ...

The MC shown in that post is a 1961-64 BIRD SGL RSVR- SINGLE OUTLET -

If you notice, the 1965/66 MC had a larger/taller reservoir to hold the extra volume of fluid needed to actuate the calipers.
