59 FLH frt brake springs ??

#1

Post by neilw » Sat Oct 13, 2018 8:39 am

I am having trouble figuring out if I have the right brake springs for the front brake on my 59 pan.
I have 2 basket cases ,and 10 years or so ago started to assemble one from the parts . I sold some off what I new I wouldn't need as I'm only building one bike .
I lost interest several years ago and just the other day decided to start work on the bike again.

Back in 2012 The end pulled off the brake cable ,and I ordered a new cable and shoes too.

Everything sat in the box for 6 years ,then I decided to replace the cable and shoes.

I had an impossible time getting the springs into the shoes,and now am convinced I have the wrong springs ,and the reason the end pulled off the cable in the hand lever is because the springs are probably Master cylinder springs ,or something similar, and far too strong.

tomorrow I'm going to see if I can dig up any more springs , meanwhile I attached a photo of several springs, and wonder if anyone can tell me if they might be front brake springs .

All the springs in the photo have the little hooked ends moving independently inside the spring. You can rotate , and push the hook part in and out.
I wouldn't mind getting my bike together for spring as it's in my way every time I go to the fridge , or stove . Lol.

I just checked a front brake spring I have laying loose on the bench. It looks like the top two in your pics and is 4-5/16 inches overall length, measures across the outside of the bent ends. Hope this helps..... RooDog

Thanks ,
I was hoping the bottom one was one of them. The top ones are what I had such a hard time installing .

Make sure when you install them to have them in the notch closest to the backing plate, If not they will rub on the brake drum. DAMHIK

Thanks you guys for all the help . I counted the coils on the photo of the assembled brake springs , counting the little coil at each end too , the photo shows 27 coils in the spring, mine have only 24 , also the photo shows longer tails coming out of each end
.
I don't know how mine got on , but it sure wasn't me who put them on .

I have been fighting with this problem for 3 days now ,including manufacturing a spreader to spread the shoes so the cam will fit in between the shoes .
It was a bit of a struggle even getting the springs mounted on the shoes with the cam not being in place . I was able to install them with the use of my spreader , but it didn't make any sense that it would be so hard , especially since neither of my manuals mentioned anything about it being difficult.
They look very much like the foot brake pedal return spring on my bike

I tried everything I could think of that you guys might have done to get your springs on . The last thing I tried before ordering new ones from the Harley dealer , was I put a screwdriver into the loop at each end of the spring and grabbing the shaft part of each screwdriver ,I tried stretching the spring , nothing happened , It didn't move , it might as well been a solid chuck of steel.
That's when I was certain I had the wrong springs.

What a relief, just knowing that it wasn't me too stupid to put ordinary brake shoes on a backing plate while everyone else had no problem.


And thanks for the reminder to place the springs in the notch closest to the backing plate ..

Hey Excaliber ,
On your blog ,on the very first picture , I can see a glimps of the relay bracket , but I don't see a relay.


I have the relay bracket ,part 74765-47 and my parts book shows it takes 4 bolts and washers . I see where 2 bolts hold the bracket to the engine but have no idea what relay is supposed to bolt to it with the other 2 bolts.
No parts book or my vintage restoration catalog show any relay at all.
This is the little chrome plate that mounts to the engine case right ahead of the distributor.

Since they used it from 1947 to 1964 it must have something that bolts to it called a relay , but I dont know what it might look like ,and further to my puzzlement , my wiring diagram doesnt show any wire that goes to anything called a relay.

Can you shed a little light on this ?
Beautiful photos on your blog .
Neil

Earlier Pans run a 3 brush generator and a relay for it mounts at the location you point to. From about 1958 a 2 brush generator was introduced which uses a cutout/regulator mounted elsewhere.

My bracket has the horn trumpet bolted to it plus the timer control cable.

Have you tried this? Fold the two brake shoes like a taco and place the springs on the studs as needed, and then flatten out the shoes as installed. You should be able to do this and capture the stud and cam too.... There is no need to wrestle with trying to stretch the springs. RooDog

Fold the two brake shoes like a taco
This is how I do it also. Much easier than trying to stretch things open.

The relay is also called a cutout relay, or sometimes just a cutout.

Some people even call it a regulator, nut it really isn't one...

With all my doubting that my Front brake spring would be so hard to install , I ordered a new set.
The Harley Dealer called to say they arrived, and I took a sample of what I had been trying to use with me .

The owner of the shop took one look and said that I had a side stand spring , and it would never be suitable for brakes .

I brought the new correct ones home and what a difference .

I attached a photo of the 2 new brake springs , compared with the side stand springs .

I will be asking you guys more questions , but not about front brake springs .
Thanks everyone who helped .
Neil
