With the shim fitted
Hi All. My name is Jonathan.
Ive been lurking here for a while, but this is my 1st time posting a question. I drove my truck home (76 I think F250 4wd)
and heard a horrible sound. I jacked it up, took the wheels off and the brake calipers fell off. They were missing the Shim and retaining spring. Not sure of the correct term. I sourced the parts, I fitted the left one, and it was snug. I had to tap it in. The right one, however, there is a large amount of play. While problem finding, I noticed the space between the top and bottom caliper bracket( again not sure of correct term) on the right one was 5mm more than the left.
Any suggestions?
thanks in advance.
Does the T shaped key (caliper support key) #2B487 look exactily like the other one? Or is the loose one missing some of the inner T material? The on ein your pic might be missing some. Yes with a difference in the measured gap on the caliper mount bracket, something is amiss for sure. Does the one (2B304) with the bigger gap, upper and lower joint points (caliper to bracket) look ground on (grinder modified)? Also does the caliper body (2B338) themselves measure the same?
Yes this is a 1/2 ton single caliper, but at least it has names.
Thanks for the reply. So much easier to explain with the diagrams. Thanks..
It is possible that it could be ground on, thought maybe it was wear and tear, but not sure exactly. I measured the caliper bodies. And they seem the same. I measured as accurately as possible. The T shaped caliper support key I think is standard. I took them both off a F250 2wd. I understood they were interchangeable between the models? I tried both support keys on the left caliper (. The good one. ) and they both fit snugly. So I don’t think that is the problem.
Im thinking the best solution will be to replace the caliper bracket (2B304)?
Exactly why I was asking, thanks for the pic of the caliper support key. Until Number Dummy chimes in, I bet that caliper bracket is going to be hard to locate. In your location probably even harder.

These brackets are right & left specific. OP lives in South Africa where they drive on the "wrong side" of the road.
1976/79 F250 2WD & 4WD w/dual piston calipers. Also same as 1976/79 E250/350 (Econoline), 1976/79 F350 2WD & 1979 F350 4WD all w/dual piston calipers.
D6TZ-2B304-B (replaced D6TZ-2B304-A) .. Right (passenger side US/Canada) Caliper Support Bracket / Obsolete
D6TZ-2B305-B (replaced D6TZ-2B305-A) .. Left (drivers side US/Canada) Caliper Support Bracket / Obsolete
No Ford dealer or obsolete parts vendor has either side, none on ebay.
The caliper with bracket is available easily, the original Dayton caliper and brackets are made aftermarket. I will also say that the later style single piece caliper bracket combo does fit these trucks and the end result is the gap you see in your picture. Can you confirm the caliper and bracket are two pieces?
Hard to locate, as in available OEM parts wise. And to confirm you do have a DUEL piston brake caliper on there correct? And you do know that there is a bolt (key retaining screw) that holds the caliper support key in place once installed. It threads into the support bracket, and is inline with the one the 1/2 moon cut outs on the key itself.

This is the caliper that I mentioned fits but is from a later truck. This creates a dangerous situation because it is smaller and will pop out of the bracket. Just like the OP is reporting. Don't use this on any 73-79 truck. Some have tried and they use the same brake pads but this caliper will pop out of the bracket.
I know that the caliper (piston part) and the bracket attached to it can be separated. And both can be located easy. And that the caliper piece (ordered loaded) you get the outer bracket attached to it.
The part I think he is needing is the part # 2B304, "caliper bracket" in the above pic.

The bracket on the axle isn't what he needs, look at the caliper. That is the wrong caliper on the axle, the OP needs to take some better pictures of the caliper but the bracket on the axle appears to be just fine.
The pics in post #2 show a measured 1/2" difference in the axle mounted caliper bracket "gap" that the caliper itself sets in. That is why I thought he needed the axle mounted caliper bracket. I agree it could be that he has the wrong caliper assembly all together.

That is a metric tape measure, notice it only has 10 gradients instead of 16. Also unsure if the OP is measuring from the driveway up?
