 Posted: Wed Apr 23, 2014 6:40 am Post subject: FRONT drums, Chevy pattern?? |
 |
|
I've done the search, I know the topic has been discussed. However, I have not seen a definitive answer.
Is there a source for front drums(link pin) with a Chevy pattern?
If not, are blanks available?
Thanks

The problems for the front...
You cant drill the wide 5 front drum to use a smaller pattern.
4 lug style front drums wont fit a Link Pin Spindle
No conversion front drum available.
2 options.. to use Chevy pattern wheels on a Link Spindle front...
Switch to disc brakes
Use adapters.

Ok. That's what I thought. It's been years since I've looked back into this, I thought maybe someone came up with a different option.
Thanks.

I have been doing a similar search, and found a European distributor that carries blanks, and they advised me to contact one of their US sales outlets. I haven't done it yet, but here is the thread with the details. Perhaps if there was enough demand, they'd stock them, or be willing to special order a few sets. http://www.thesamba.com/vw/forum/viewtopic.php?t=4...p;start=20
I'm running adapters for now, but don't love them. I recently bought a new set of rear drums with Chevy pattern and studs from So Cal Imports. I hope to get them installed in the next week or so. |

Even those blank drums won't do as they're for ball joint front ends. |

Yea, I saw that. And even if they worked, it would end up costing me more than disc brakes. I just want to get rid of the adapters so the tires move in 1". PLUS... since disc brakes are a bit overkill on a buggy, the 5 min drum installation was the most appealing aspect.

jetski,
I agree, slipping a set of drums on my freshly rebuilt front brake system has a lot of appeal as well. The rear drums I bought from SoCal Imports with the Chevy pattern were $72 each, and their blank rears are $47 each. If I could get the front drums drilled 5 x4.75 for $72 each I'd buy them. It would be a great deal less expensive than converting to discs, to say nothing of the extra labor. |

| This thread got me off the dime and I called CIP1 today. They are going to try to source front ball joint drums in blank or Chevy pattern. I'll post back here and on the other thread if they are able to get them. |

Why doesn't someone make K&L drums with a traditional center raised hub, instead of the big radiused hub? The hub would be a bit large because of the larger bearings, but plenty of USA RWD cars had large center hole diameters.
I like the radiused drums (front and rear) because I'm leaving them exposed on my mini-t for a bit of a late '30's Ford hot rod brakes look. Still if i want different wheels going forward it would be nice to have drillable front drums available.

Not enough demand = no product produced...

I suppose, but the width of the front brakes is the same as the ball joint cars. It would seem that they could just slightly thicken up the hub section of the ball joint casting and have a single casting that could be K&L or ball joint depending on the finish machining. They could turn down the outer center when needed (ball joint only.) It could be one casting fits all (1958-1977 USA.)

I believe the European source for blank front drums has both ball joint and link pin styles. |

They only list ball joint ones on their website and in their catalogue. |

Bringing this back up....
Some research.. there may actually be a conversion bearing that.. could possibly work..

Looking in the 2011 Empi catalog on pg 303 they are showing conversion bearings for installing a ball joint brake rotor on a king pin spindle.
#17-2795 inner
#17-2796 outer
I heard of it being done before, but had never seen a reference to what bearing were used. |
Those bearings are made to install a 4 bolt rotor onto a King Pin Spindle, for the inexpensive disc brake kits for buggies, that don't necessarily want to keep the 5x205 bolt pattern. The bearings aren't anything that is a "stock" size. The inner race will fit the KP Spindle, but the outer race is custom ground to fit the BJ Rotor. With those bearings it will be physically possibe to install a 4 bolt BJ Drum onto a KP Spindle, but if you're wanting to use a KP Backing Plate with the brakes, I'm not sure how the shoes will line up. |
Hmmmmm... interesting..
I know it claims rotors... but aren't the later ball joint drum and disc bearings the same size (OD) ???
May have to modify a brake backing plate to work.. but I really dont think so..
Somebody needs to try it.. as it may solve a shit load of wheel issues..
I see many suppliers offer these..

My 57 pan has Chevy pattern wheel adapters on the wide 5 drums.

I see nobody touched this so I thought I would at least share some of my observations.
It is often reported that the conversion bearing route to K&L disc brakes moves the tires out quite a bit. The bracket that mounts the calipers is pretty beefy looking and flat, also suggesting a wider stance. It is possible the drum would mount farther out than stock. But if that is the case it should be possible to move the backing plate out with a suitable adapter.
Are the link pin spindles longer than ball joint spindles? Is there a longer seal race or spacer used with the conversion bearing for the front disc using the stock rotor? If the conversion bearings (and related parts from the kit) are used there is no reason the ball joint drum shouldn't go on like a rotor, but it may be in the wrong place.

My thoughts exactly.
All it takes is someone wanting to try it..
Maybe in time.. If nobody tries it, Ill pick up a set of conversion bearings and see how they work out. I have no desire for this conversion, but I am quite curious.

Several years ago I bought a set of LP spindles that had been converted to disc brakes with all new parts and set up for 4 lug wheels. When wvbowtieman was building his Lithia, I measured them and came up with either 1 1/4" or 1 1/2" wider wheel track over a stock LP drum, per side.

| I'm sure it's been posted before but I can't find an answer. WHY can't wide five link pin front drums be re drilled to a chevy 5 lug? Sorry it's an old post, but it had a relevant topic and I know how much Everett loves new topics created... |
