Brakes

Yes, I do have the vacuum reservoir, but I do not have the correct fuel pump. The fuel pump only has one line and that as to the carb.

Gary, just a quick thought, if I had the correct fuel pump, I still would have no vacuum if motor is not running. So in my case I still would have no brakes.

Jim, I guess I missed something here. Where is the picture that shows the pins at an angle.

Go back to post #14 and Dgasman added a picture.

Quote from: alvin stadel on 2021-11-11 09:11I have had huge brake issues on the 57 RHT that I just finished. I have got it so it will stop very good, but it still isn't right. I hope this will make since, I am not sure if this is part of my problem or not. The 2 pins that go from the shoes to the brake cylinder are at a angle, not running straight across from the shoe to the cylinder. When the brakes are applied the pins do push against the cups in the cylinder, but I am wondering if they are not being activated all the way. No matter what I do I can not get the pins to run straight, any ideas. I am beganing to wonder if they sent me the wrong shoes.

Below is correct assy of the front brakes (57 drum)-

If the pins are not square, it has incorrect parts and/or assembly. The shoes will not be activated correctly.

QuoteThe correct fuel pump will provide vacuum for wipers and booster.

A TWO STAGE MECHANICAL FUEL pump only supplies vacuum to the vacuum wipers when manifold vacuum falls enough to not operate the vacuum motor.

If you have a cam that produces too little manifold vacuum to operate a booster and you have added an additional electric vacuum pump to supply the booster and there is no stopping power when the car is not running, you have a bad (or no) vacuum reserve tank/vacuum check valve.

That vacuum reserve should give at least two emergency stops without the engine running or the electric vacuum pump not running/failed (as long as that reserve tank has not bled down and lost vacuum).

I am assuming that is the RF brake assembly, with the front of the car toward the right side, if so, the brake shoes are installed incorrectly. The short brake lining should be on the front, and the longer shoe on the rear, opposite what this shows.

Been a long time since I have done drum brakes but, it seems that the orange spring is incorrect for 57.

Yes, they are. So much for my proof reading ability.

Why would you say that?

SkylinerRon · 2022-09-26 18:37

I don't remember ever seeing that spring on any brake job I have done. Probably thrown away by who ever did the first brake job and they were not in the hardware kits back in the day. When I do the brakes on my 61 Starliner i'll look for them.

The truth is Ron, is that the third spring was added during the production run, I had a TSB but have lost the darn thing.

But is it agreed that the photo I showed is correct assy (other than side) relating to the wheel cylinder pins?

SkylinerRon · 2022-09-26 20:51

I don't have that TSB either, thought I had most of the 57-60 TSB's. Maybe someone on here has one we could get a copy of.

Ron.

BTW ...

My SEP 1956 ISSUE 1957 FORD WSM does not show the 3rd spring while it is shown in both a SEP 59 ISSUE MPC and FINAL ISSUE MPC.

I am still looking for that SERVICE BULLETIN -

Concerning This Brake ASSY Detail -

BRAKE - 1957 FORD - BIRD - Frt _1.JPG

It is shown with the shoes installed incorrectly for the RS of the car. But it does show correct ASSY although it is for the LS.

Either the guy screwed up or as the backing plates are the same L and R, he may have bench assembled and installed on the incorrect side.

Who knows?

... 2nd time I have been caught on that photo. Looks like I would have learned the first time ...
