Doing disc brake conversion and I need to change out the rims--what to get?

I'm having a mechanic change to '64 Deville convertible to disc brakes. He used the spacers that came with the kit but one side takes 2 spacers and the other 3, and there is a slight disconnect from the center hub from being so far out. It appears the best solution would not be further tinkering with spacers but a deeper 15" rim made for disc brakes. Does anyone know what rims might work that will allow the existing Cadillac hub caps to fit?  

I have read everything I can find on disc conversion but don't see this question answered, though some people seemed to be changing out the rims.

That's a very important comment, actually. I bought mine from PPC, which was cheaper, but it has caused a lot of trouble. Still not finished and has been at the mechanic for a long time. Neither new wheels nor hub spacers are the perfect solution.

This would be 20 20 hindsight but hopefully it will prevent others from having the same problem. When I converted my 64 coupe to front disc brakes I bought the kit from ABS power brake. They have a kit that takes the stock rim without any spacers. Worked great.

It would be great if Preston could supply information about the kit bought. And pictures of the installation and all. There will be someone wanting to do this later and could learn from this experience.

What matters is the distance between the tires. If the distance stays the same as original there will not be much more stress on the suspension and steering. It all depends on the design on the new brakes and the rims used. Then the spacers has to give the same contact surface as the drums would give on the rims.

So spacers that provide a good contact surface and a setup (rims) that does not increase the distance between the tires should make it safe and good.

Tony, its spelt..... Australian. :-)

To clarify, I've seen people use spacers for years with no issue. Not something I would do, as I believe it has an adverse effect on the studs and can result in snapped wheel studs.

How long have you been using the wheel spacers with no issues ?
Thinking you answer may help support your position on using them
Especially if it has been a good bit of time

Do you have any pictures of the spacer on the brake drum ?

I am sure Kevin was saying the same thing i just did ( in Austraillian )

The stock hubcaps will only fit the stock rims on the 64 as best i know
The stock rims require a special kind of -balancing weight -on the front of the rim for the stock caps to fit as well

Russ's idea is looking better if your need is stock rims and look -which it is

You have any pictures of the parts and the setup? Pictures really helps if trying to find a good solution.

HVAC Vacuum Valve Clip-need the one for the Power Control side

Posted by Norman Silverman on September 17, 2018 at 8:15pm 6 Comments



I removed both 7 nipple vacuum valves and called my buddy who owns a machine shop. Tomorrow we'll re-surface the valve faces and then I'll reinstall them. HOWEVER, the one that comes out easily and comes apart with no rivet is on the Power module side. It installs on one side with a small bolt, and on the other it is held on by a clip, WHICH IS MISSING ON MY CAR. I am going to assume it is the same clip that is used on the Control Module side. Anybody got one? Happy…


7 vacuum valve-need a good one or someone to recondition mine

Posted by Norman Silverman on September 15, 2018 at 5:44pm 12 Comments

So, I've put my 7 vacuum valve from the control head side to the test, and it failed. I looked at the instructions for re-conditioning it and unless I am missing something, the instructions are missing something (about how to take off the clip that provides the tension that holds the two pieces together). 

In any case, I can't do this particular repair so I am looking for a new valve (not likely), or a good re-conditioned one, or someone who has done this before and would do mine for…
