|
|
Are brake drums interchangeable between different bolt patterns? Currently I have 5X205 pattern up front, and 4X130 in the rears. Can I get a 5X205 for the back or 4X130 for the front? Trying to buy new rims and seems to match styles I need to match bolt pattern.
If I can't utilize brake drums in the pattern I want ( vehicle may need new brakes anyway) is there;
Any advantage to certain adapters or to going to 4 or 5 lug? I found some wheels I like in 5x205, so could just get the adapters for my existing 4 lug to go out to the 5.
This is a rail that will be set up for offroad, woods running.

These adapters are fine to use.
Some say the four lug drums with adapters are stronger than the five lug drums. _________________ My Build: '69 Baja - Dark Earth Version

Thing front brakedrums
Thing Rear brake drum
I would investigate Thing bearing numbers, they may be different from Bugs because these were used on kinkpin cars _________________ 73 Beetle Baja, Ghia front brakes, Type 3 rear brakes, 2220 ( 94 X 80 ), Weber Progressive, Bosch SVDA, '97 Mustang seats

I have 4-lug drums on the back. But I have 5-lug wheels all around. I use those same adapters shown above for 5-lug wheels all around.
I've worked the car quite hard offroad with absolutely zero problems other than when somebody tried to steal my left rear wheel.
You already have the 5-lug front drums. No need to try to adapt the Ball Joint Bug/Thing front drums to get 5-lug. They WOULD work for the rears, but at about $50 for the adapters, vs about $210 for a pair of Thing drums...Your choice.
I suppose it's possible to adapt 4-lug drums to your king pin spindles with the correct bearings. But I don't know of anyone having done so, and don't know which bearings would do the job. _________________ Richard

I have used those same adapters as well with zero problems. I do run pressed in and tacked studs in mine but I doubt it makes much difference and costs more, it just makes it easier for me and my old back to throw a tire on. _________________ HRE in Westerville,Ohio

BTW...
Rear brake drums are interchangeable to a certain extent. The spline is the same, but the length of the spline varies. Early swing axle has short splines, Bug up through 1967 year model. 1968 Bug swingaxle, Bus, Type 3 swingaxle and IRS, and all IRS Bugs use long splines. Short spline drums can be used on long spline axles if you add a spacer outboard of the drum. Long spline drums can only be used on short spline axles if you machine the outer 13mm or so off the center hub of the drum.
Drums must match backing plates. There IS some interchange, and all backing plates fit all bearing housings, swingaxle or IRS. Shoes and related hardware must match both backing plates and drums. If you have long splines, early wide 5 lug pattern small nut reduction box Bus drums and backing plates can be used. _________________ Richard

My flaps set me up with some bearings that allow a 4 lug rotor onto my link pin spindles. The rotors came off of my old ball joint spindles.

Do happen to have the part numbers for those bearings? I'd like to do exactly the same thing!

I made my own out of 1/2 aluminum, of coarse I had access to a water jet machine at the time.

I think they are empi conversion bearings. Got em from archway imports. Sorry, all my reciepts (shoe box full) only have part numbers with no description of the parts. _________________ My cut in half and rebuild thread

Well I got the adapters. 12*1.5 thread, but I can not seem to find a conical lug bolt that is that thread and short enough for the adapters.

It's made for stock 5-lug VW lug bolts. They should work fine. Should not be "conical" but ball.
The alternative is reaming out the lug holes and installing lug studs from Sway-A-Way and Empi/Bugpack. _________________ Richard

For adapter to wheel..... Use studs.....
Look at Dorman product to find proper stud... Press in studs and get proper nuts and the world is fine.... Look in section 10 of document below....
https://www.dormanproducts.com/flipbook/dorman/automotive-hardware/2006-automotive-hardware.pdf
Think the 610-254 will press into existing holes on adapter with minimal modifications....
Proper lug nuts will be in next section....
You can order by Dorman part number through places like Rockauto or maybe local AP...
