Brakes, bolt pattern woes..

[SiggyManx#33]

I'm working on a link-pin swing axle pan that is in need of a full brake refresh. By refresh, I mean all new brakes. I have my wheels picked out and the are chevy pattern.

Questions:

Is it more cost effective to use all new drum components with adapters.

New front Chevy discs with rear drums and adapters. (Chevy pattern rear discs are sold out for the foreseeable future)

One thing to note….the wheels are on the wide side and while it may be less of a problem in the rear, I'm concerned in the front about the extra track.

Or…any other options?

Thanks for and input.

Do you know that the wheels you have will clear disc brake calipers? Some vintage style wheels won't.

Chevy pattern drums may be available for the rear. I was able to get them for my '72 IRS. I'm running adapters in the front, and while they extend the wheel out about 3/4" they work fine. Pay close attention to backspacing when picking your wheels.

Front disc and rear drum will require proportioning. Can you get rear discs that are blank and have them drilled and studded for Chevy pattern?

[EVfun]

I would not recommend converting only the front to disc on a buggy. The front is to light and it will just lock up. All disc or all drum. Adapters for wide five tend to add quite a bit to track width. Will that will work with your buggy? I like the stock drums as they are more than enough for a light buggy.

These are the wheels….A bit wider then usual, but should look pretty good.

I could probably buy blank rotors, but just complicates things. Do front disc only make the car un-driveable?

I would do whatever it take to not run any kind of adaptor so the wheel bolts directly onto the drum.

I'm in exactly the same boat as you, I got the chevy pattern drums for the rear and searching left and right for a front drum, blank at least, but all evidence point to plug and re-drill.

[EVfun]

The problem with only front disc brakes on a buggy is that the weight loss isn't even. The engine doesn't get lighter so overall the weight bias shifts rearward. Combined with the big and little tires generally used front braking doesn't need to be stronger.

Torque Thrust D type mags are the type I heard won't clear the brake calipers

[Singerdude]

Bingo! Found a blank front drum, it's rather expensive but less trouble than shortening the beam, and less dangerous than re-drilling a 4x130

The undrilled balljoint style front drums are available by special order for $69.95 each plus $15.95 shipping from CiP1.com. They are not on the website, but if you talk with customer service, they can order a set from the wholesaler BBT.

[Singerdude]

I called Cip1 this afternoon, the guy told me that it would have to wait their next container shipment from europe, wich may take 2 to 4 months. he told me that he would check for the possibility of having it shipped by air but he hasn't got back to me yet. Is your info fresh?

With the euro to Cad$ and insane shipping costs, if I take them on the french site it's almost 400$

So I will call Cip1 first thing in the morning monday...

[andygere]

That was basically the same info I got a few months ago. I've been running adapters up front, and haven't ordered the drums because I've really been too busy to deal with it. The adapters work fine, but they add about 3/4 inch.

[Singerdude]

I just can't run the adapters...

I miscalculated my front wheels measurements by a lot. With the adapters, they stick out like 3 1/4 inches. That's a drag because the rear are almost perfect. And I looooove those freaking wheels, I really want them to fit. So I will get the drums and then I'm gonna fiddle with Beam width and see how that goes.

[Singerdude]

I have another thread talking about this, and another member manifested his desire to get the drums also, so maybe if we are a couple guys ordering at the same time, they will be more inclined to proceed...

[andygere]

Singer dude, that's a good idea. I'd order a set of CiP1 was willing to expedite for a reasonable cost.

[andygere]

By the way, the rear drums I purchased drilled and studded for the Chevy bolt pattern are very nice quality. Here's a shot showing them just before I painted them.

Dave, My yellow buggy has ghia disc brakes on front with type 3 drums on rear. I have not had the front lock up during heavy braking. Bud runs disc's front and drums rear, his car will stop on a dime. I'm not sure what type of calipers he's using.
