Rear Brake Hanger 4th and 5th gen


slo1

Question

  • Member Contributer

checking if there is any interest in custom rear brake hangers for 4th and 5th gen's. On 4th gen it's pretty much just cool, maybe save afew pounds, but on 5th gen it will make DeLink way easier. 

The hangers are made to use Brembo 84mm calipers, which are relatively cheap. Also good for the Beringer Mini ($$$). Possibly over slung, but primarily under.

Price would be dependent on how many we can get to commit. 150-200 is my guess.

Now that eyrwbvfr has showed up, from the Hawk Forum, if you want a 5th gen hanger he is your man.

 

The 5th gen full hangers hit a dead end after the proto type, due to the machinist getting overwhelmed by life.

I will have a small batch run of 4 pieces being made that will adapt an 84mm caliper to the stock hanger.   PM me for details. 

The advantage of an adapter is that you don't have to take your rear hub assembly apart.  

But it can only be underslung. 

 

Thanks Dale!

Any idea on how much these are going to cost?

I should have parts this Friday!   Hopefully.   One caveat for the Brembo caliper.  You must get the version where the bleed nipple is on the side closest to the mounting ears, opposite of the banjo bolt.   I got the version where the bleed nipple was farther from the mounting ears and the same side as the banjo bolt.   It completely crashes the spokes and the tire valve.    Luckily, I have the correct caliper on my Hawk and I simply swapped calipers.   On a Duc (or a Hawk with a Duc wheel), there is plenty of clearance.   I'll post pics when I have the adapters in hand.    Also, I'll post pics of the two calipers.    It's late now.  ZZZZZ.

Got the parts back today.    They look great!  I will fit them tonight to double check it.

 

PM me if interested.   The price is better than originally quoted.  They are now $125 plus shipping in CONUS.  About $8-10 by USPS Priority.   I have four available.

 

Make sure to get the caliper like the one shown, noting the location of the bleed nipple for correct clearance of the wheel spokes.

I bolted up the caliper and went for a ride!

 

Great fit and in the same place as the OEM caliper.

 

I have 3 left for anyone interested to do the same mod.

Cost came down a bit to $125 plus shipping.  I have 3 left but 1 pending.

Depends which way it's pointing.   If it's on the same side as the mounting ears, it's away from the spokes.   Basically, when mounted, it should be pointing to the left of the wheel (the open side).

 

Based on the assembly bolts being on the left side, I'd wager that caliper is good to go.   Will need a side view.

Any reason not to use a caliper with the side bleed and banjo? Like this:

If it matters, I'm running 83 degree Bridgeport valve stems.

That is what i use with the full adapter proto type that was never put in production. works great.

I mounted up the adapter and it fits perfectly. The caliper I got matched up nicely, but I didn’t get to mount it. I couldn’t get the pad pin out, and also the bleeder screw wouldn’t turn. So I’m returning it and will resume the search for a suitable caliper.

Sorry for the crap pics...

Update:

The caliper pictured above was kinda trash. It was dirty, I couldn't get the pads pin out, and the bleeder screw was so tight it was damaging my wrenches trying to loosen it. The "pads" that came with it were basically 100% metal with the barest hint of friction material. Based mostly on the fact that the bleeder was welded in, I sent it back for a refund. I found another one for about $10 more, but came with nearly new pads and was pretty clean. I did figure out how to get the pads pin out, that was on me with the first one. It has some sort of spring collet holding it in, plus the clip on the back. 

 

Initial test fit:

Left side:

(Note the position of the banjo opening and bleeder. More on that later)

Wheel on, clears the Bridgeport 83' nicely:

Right side, peaking through the 8 spoke:

From the inside, plenty of clearance to the wheel:

Only issue I had was the inside pad (toward the hub) fouled on the new adapter bracket. Here's the pads one on top of the other to show where I trimmed the backing plate:

Striped for cleaning; I noticed that the holes for the banjo bolt and bleeder are identical. Both are conical at the bottom to fit the bleeder. So I am going to reverse them to have the banjo at the back for easier installation. I think my line would reach, but it's better in the back:

Identical on the inside:

Clean and ready for re-assembly:

I stuck the seals and pistons back in there after this pic:

Since it's a proper Brembo piece, I am going to treat myself to some tasty bits for re-assembly and mounting.

Planning to weigh it assembled and compare to the hulking stock triple piston slide pin monstrosity currently still attached. Next I need to drain the reservoir and line and free the stock caliper.

Check the piston diameter.  I used P32, which is the smaller 32mm vs the larger P34 34mm piston.  The difference in the corresponding pad sizes may explain the interference.  The corners of my pads just barely miss the adapter.  No pad dragging on my setup.
