Mounting ebrakes
 

Is this one mounted correctly? Specifically the spring attachments? Does it have a grease baffle, I think it does but not sure? Is the ebrake shoe supposed to be on top of the backing plate as pictured?

The brake bands are not supposed to overlap. Not sure from the photo what you have wrong. There is a left and a right once assembled.

I found this image online for you.

Why are the shoes twisted so far out? There is a left and right on the ebrake shoes.
Dang Tom was quicker on the draw. :)

Don, I am confused. Are you talking about the adjusting shaft pins or the actuating link pins? Both the above photos show the actuating link pins head in, which is opposite SB page 264. The actuating shaft pin in the first photo shows the adjusting shaft pins as in Les Andrews book pg. 1 - 41 and opposite in the second photo, making Tiny's photo of the adjusting shaft pins wrong.

Actually it appears in the second photo that one actuating shaft pin is head in amd one head out.

Okay, I get it on the linkage (mine was also incorrect). So, even though it isn't ebrake related isn't the adjuster shaft pin installed incorrectly on Tiny's post?

x2 on Don's second post.

Re: Mounting ebrakes
 

Mag and Don, I still don't have my question answered about the brake adjusting shaft pin and roller pin orientation answered. L.A book pg 1-41 shows the adjuster shaft pin and roller shaft pin from inside to out. Pg 1-43 appears to show the adjuster shaft pins outside to inside and the roller pins inside to out. Tiny's picture appears to show one shaft pin inside to outside and the other out to in. No mention of direction in the written instructions on page 1-42. I would like to get my brakes back together correctly but it is difficult with the conflicting information to determine what is right.

Re: Mounting ebrakes
 

The below photos, right hand rear brake and emergency, should clear up the orientation for you.

The cotter key, (aka split pins) are installed outboard on the service brake shoes so the anchor pin can slide on the roller track.

The emergency brake cotter pins, (aka split pins), are installed inboard so they do not drag against the drum.


Hope this clears it up for you.

Re: Mounting ebrakes
 

If you have the proper E-brake clevis pins you will notice that they have a very thin head. The pin should be oriented with the thin head outboard. The purpose being so they don't contact and score the drum when installed. This puts the cotter pins in board in all four positions. One pin is longer to accommodate the extra thickness where the two linkages come together.

The photos in the first two posts show the parts assembled wrong. The one just above is correct.

The hardware can be assembled such that they are either a left or a right. There is an eccentricity to the parts, so you have to be careful to assemble the parts so they are in a straight line.

Tom and 160B, I think I have it now. 160B I don't see a picture but get what you are saying. Thaanks, John

Re: Mounting ebrakes
 

That's what I thought and did. The L.A. book is excellent, however I find it hard to determine what some of the illlusrations show. On things as critical as this I would rather depend on written discreption than what my tired old eyes see in an illustration. Thanks for the help.

Notice that the parking brake bands must have the retaining springs in the OUTER holes, and NOT the inner holes, so they don't snag on the support plate edge.

Also notice the bracket on the band where the toggle is pinned has a high and low area, as viewed laying flat on a table. The low area is what rests on the support plate and the toggle hole is higher for clearance, so as to not hit the support plate.

Also in your first picture, the roller cam is not engaging the rollers correctly.

Notice in my picture the parking brake lever is not fully retracted, because if it was both ends of the band would be resting snugly against the support plate and the double thickness stop tab.

I also grease all moving parts, including the brake spring ends, but haven't done it in this picture, because a friend had this assembled before I arrived to help. I later added grease by using a small brush.

As mentioned, the friend also had the pins in backwards, and I switched them so the heads faced out.

OK, here's a better picture that I wanted to post in the first place.

Re: Mounting ebrakes
 

OK one last question. Which way does the wide side go, outward or inward?

Re: Mounting ebrakes
 

I notice my backing plates don't have the several tabs to hold the ebrake shoe there.

Re: Mounting ebrakes
 

Your picture in #17, the laft side faces the backing plate.

The tabs sticking up around the support plate are a later improvement, but I'm not sure of the date for that change, but probably during 1930. It might be in the Service Bulletins.

Also I noticed in your first picture the axle shaft key has the taper on the top outside end. It should go down and on the inside of the keyway. Maybe your key has a taper at each end, so it doesn't matter.

Re: Mounting ebrakes
 

I'm sure this is a bit late now (by 8 months) but maybe this will help someone else. The left side in your picture is the side that goes against the carrier, but I'd install the pins so the head is against the carrier. I don't think the cotter end of the pin has enough clearance as pictured, and may hit the carrier. The two band retention springs need to be hooked in the outside holes on the band brackets for the same reason.

I see I do have the cotters facing in on my picture in reply #13, so I guess they do have enough clearance. I'm going to check this out to be sure. I haven't done any brakes for about 3 years now.
