The hardest part is finding steel pallet strap, much of it these days is FG.

Good Luck!


Found it- here's one I did lately on a Super Beetle, it worked like OEG.

Did you just press in the "v" that drops Down into the grooves in the stars?

I think I just pinched the band sideways in the vise to make the "V".

Measured the remaining one on my ear brakes and it's 10mm x 50mm. I just laid the end of the sprung steel on top of a slightly cracked vise and used a chisel to put in the "V". Then it will simply be a matter of cutting the scrap to that 10 x 50 size and tacking it on (or drilling and screwing). Just noticed it looks like it's cracked and my finger is showing through...it is not.

Did you weld to the casting? Have to use TIG, right?

You were able to MIG the pallet strapping stuff to the casting? Didn't think that would work. Did you heat the casting at all first or just tack away?

I'm not sure if that's cast or just mild steel, but I did not preheat it. It's a low stress connection. The original mounting is "crimped" where the block is deformed to retain the spring which makes me think it's not cast. I think cast would be too brittle to crimp the spring into place.

There's something cracked in your picture and it's not the spring. Dude, use some hand cream and rubber gloves......

Very Happy

The spring is crimped in the channel and it's 10mm wide (50mm long as I said before).

I was able to get the new fabricated piece into the old uncrimped groove, and get it solidly seated! No drilling...no welding. Very pleased. I bent the middle a little so it would decrease it's width. Then, once in the correct position I was able to use a punch and hammer to flatten it out...increasing its width, into the old groove.

I made some once using a strip of sheet steel from the hardware store. I attached them using hollow aluminum rivets also from the hardware store. The rivets worked well, but didn't turn out real pretty. I was happy with the fix overall. This was for front brakes on a 64.

Is the one on the left the original? Mine are a little different, but what you made should work. Nice fabricating!

Doing the front brakes on my buddy's '62 SC and the adjuster springs are rusted completely off. Went trolling through The Depot's hardware isle and found this cool little thing that is going to work great. It's replacement wheels for a screen door. Ground the rivet off the wheel mount and pulled out the tension spring.
I'll use a small pop rivet to attach the tension spring to the backing plate.

How were you able to put crimp in middle of fabricated piece? Using a punch? I am having the same problem with a broken spring but I cannot get the backing plate off so I have been trying to use a punch to install the new one while the plate is still on the car----not an ideal situation.

While replacing a leaky rear wheel cylinder on my '67 Bus and freshening everything up in there, new cylinders and a set of shoes on both sides, I noticed that one half of the adjuster spring leaf broke off on both sides (one adjuster star being held in place and the other not).

Okay, other than spending a lot of time trying to make some up from scratch, or locating and buying new or used backing plates in good condition, does anyone know of a source, either NOS, used or repro, of a quality replacement brake adjuster leaf/tension spring "correct" for the rear brakes on a 1967 era Bus?

I hear/understand that you can't really successfully weld spring steel to the cast housing metal (incompatible), that one could try to un-swedge the casting to remove the old and install the new spring and re-swedge, or drill small holes and hollow-rivet the replacements in. I plan to do the latter if I can locate a suitable pair of replacement leaf springs.


I found some on cip1.com for my '71 Super Beetle. I'm just now sure how to install them?

https://www2.cip1.com/ProductDetails.asp?ProductCode=VWC%2D311%2D609%2D485

Does anyone have any ideas or can you direct me to a suitable fix? Thanks for any assistance! Really!

### Edit - I've answered my own question ###

I'm case anyone else is looking for the front star adjuster leaf springs for a 55-63 ... BBT in Belgium have some in their NOS stock. They don't have the rivets though.


Keift en klok list the rivets (N134041) but the shipping is ridiculous, so now I need to work out the size and find an equivalent.

That's weird, I thought I'd posted a follow up to this just now.

Anyhow, the adjuster springs arrived today and they're correct, so if anyone needs them, try contacting BBT and asking them to check their NOS stock to see if they have more. The part number is 211 609 185B (the B is important, none of the other styles are correct for 55-63 front brakes).

I contacted BBT because they have replacement back plate assemblies made that include the springs, so I figure their manufacturer is making the springs and maybe they could sell them separately. As it turns out, they have NOS ones...

Couldn't find the correct 2.6 x 5mm DIN 660 dome-head rivets, but found some 2.5mm x 6mm ones on ebay, so I've bought a bunch and some spares to try. The DIN 660 spec seems to have a +/- 0.1mm tolerance on the diameter, so I'm hoping those rivets will work.
