1960 disc brakes

[slepysal]

Well I got it done !!! Thanks for the motivation
Of course things didn't go as smooth as they should have.
I started on the Sunday before Labor day which was the start of a heatwave here in the Bay Area.
Ran into some issues with the left lower ball joint and the upper ball joint rivets were not fun.
I had to make up 3/16 hard lines for the front ( originals were 1/4). I had to buy a 1 1/8 socket ,a 3/8 caliper hex socket and a 3/8 drill bit , all of which seemed to have diapered from my tool box.

here is the parts that I started with :



the original drums :

The tie rods came out and apart! I had ordered only the outer ones. I was unable to break them loose from the sleeve, and upon further inspection the inner ones were gone too, so I ordered inner and sleeves that took 5 days to get.
I re installed the old ones for the time being.


spindles off !! The lower ball joint on and off

[slepysal]

The new spindles on. I test fit it before the upper ball joint rivets were cut off,and yes they were a pain!!!




the 5 lug disc off and on !!




the free 15 x 8 Ralleys with 236/60r15 I had to use a 3/16 spacer

[slepysal]

I had ran my torsion bars cranked down so when I installed the drop spindles this is what it looked like when it came off the jack stands . Way cool but no way I could drive it on the roads in San Jose !!


and why driving would be a no go:



I had to tighten the t bars up before:


after:

[slepysal]

On to the master cylinder/ booster . I purchased an aluminum unit and a 7 inch booster and a proportioning valve , from different suppliers.



I ran into a few problems . First with the lines that came with the valve not fitting right and leaking so I ordered some new ones that took 3 days to get.
Second I didn't think the 7 inch single booster would work so I ordered an 8 inch dual unit... 3 days out.
The old master cylinder


I used some spacers to mount the booster brackets help clear my clutch master .

Booster fit like a glove , drilled a new hole on the brake arm for the clevis pin installed new push rod . the blue gloves are covering the brake lines


Master cylinder installed

slepysal, next time hit me up and I'll drive up to you. Looking at your post is making me want to finish mine that I have yet to finish. Thanks for the motivation

[slepysal]

I bought the first one about 3 years ago,and it sat on the shelf. I think that the seals may have gone bad.
The problem I was having was that I was unable to get the master to bleed. I bench bled it off the truck and it was fine. When I couldn't bleed the system I bled the master on the truck and there was air in it again!
I picked up a rebuilt unit ,and that solved the problem.
You can plug up your ports on the cylinder and see if it holds pressure.Man I can't stand it when a simple thing becomes a pain. Hopefully you fix it keep us posted.
Oh one more thing check your brake hose too

thanks to you both for sharing pics on your disc brake swaps !
Giany whats left on yours?

[Gianyveedub]

slepysal, I have to make a union from the old clutch line to the new clutch master cylinder. I also have to bleed the system, but that is it. Some day I will have time to spend a whole day finishing up.

Not much left !!Try royal brass in San Jose for the union.

Good job.
My 65 is on a 62 frame.
I'm looking forward to cranking my torsion bars back up when I get my drop spindles installed.

[slepysal]

I plan on installing some Langon cast headers , that will let me crank them down again !

[bigwin59]

Thanks for the pictures, I guess my son will get disc brakes for his ride later this month.

Those have got to be either the smallest jack stands or the largest break booster I have ever seen.

[slepysal]

Yup its a master cylinder for oversize disc brakes.
Just a funky camera angle,normal master,regular jackstands

Who's spindles did you use, and where did you source the calipers and dust shields? They look used, just wondering if they were.

And who's master cylinder/clutch master conversion kit is that?

Brad the spindles are Mcgaughy's purchased new.The Calipers were sourced at a local parts store (72 c10 )rebuilt with a piss poor paint job. the dust shields were purchased at pick and pull.
The master cylinder was a local parts house rebuilt 77 Vette unit with an ebay 8 inch dual diaphragm booster.
The clutch master was sourced from MP brakes,but I dont think they sell it anymore here is a link on what I did

I'm doing a 4-corner swap to disc as part of my build. VERY much looking forward to seeing how it changes the drive characteristics. I think the thing I hated doing the most on my truck was drum brake changes. Always seems like something went wrong or wasn't calibrated right and it always took revisiting. Swap looks great!

[slepysal]

4 wheel disc will be sweet !!! thanks siggyfreud
