I am updating the front calipers on my 1972 Westy to the later 73 style calipers. I have the bushing kit but seem to have a fitment issue with the front dust shields. The calipers will not fit with our modifying the shields. Do I just need to order 73 shields to use these calipers?

Also replacing my front shocks. I purchased Sachs shocks but the lower mount is too small for the attachment. What shock is a direct fit on these 72 buses?

Thanks

Do your new calipers bolt on the old spindles? I had to change spindles.
Shocks: did you remove the old steel liner where the bolt slides through?

You need to either modify the 72 splash shields, or use the later ones. People also sometimes have wheel interference
with those caliper adapter kits.

The shock mounts probably have the old shock bushing sleeves stuck on the stud, they rust on pretty tight and
sometimes have to be cut off. Either that, or you were sent the wrong shocks.

I don't know if they bolt on the spindles because the brake backing interferes with the calipers. I will modify the shields first before I throw more money at this.

What spindles did you have to use with these brakes? From a 73?

I did not realize that there was a sleeve on the bottom bolts. I will try and get those off first. That is where the bottom shock mounting point gets stuck.

Thanks

68-70 buses had smaller lower shock mounting studs/shock sleeves. Post a picture if you'd like a definite answer on if you have a stuck sleeve or incorrect shock/torsion arm combination.

A bus I worked with recently had a 68-70 torsion arm/shock on one side, and a 71+ setup on the other side. Evil or Very Mad

Your '72 spindles are fine. That's the whole point of the "bushing kit", to allow 73-79 calipers to be
mounted to '71-'72 spindles.

This is what I am dealing with. It appears as though it is part of the prior shock that has rusted to the mounting bolt.

I have been able to remove one side and am struggling with the other. I have heated it to no avail. I may have to cut this off but would like to avoid damaging the bolt

If it wasnít glowing red you werenít heating it, you were tickling it.

OXy that amd it will come off.

Thatís easily grindable too, only the outer threads are used so you could cut the barrel until it splits

Id be weary of heating that bolt too much. You dont want to weaken it.

I would take a dremel and a cutoff wheel to it very carefully. Should only be about 10 minutes of work to slice it off. Wear googles obviously.

I donít see the value of changing from a 1972 caliper to the late model. What are you trying to improve?

I don't see any traces of a liquid penetrating oil on it. Penetrating oil is a special oil that reduces the size of the rust molecules, so it helps free rusted things.

Cut a horizontal groove in the sleeve, insert sharp chisel, bang with 3# short sledge. Presto its off! I also see little value in this upgrade .

I see no value in the upgrade either. As long as the parts are available it often makes more sense to just repair what one has. The only upgrade I can think that would have benefit is taking a 1970 or earlier bus to discs and a flange in the back.

I'm in the middle of fixing a botched attempt to install 1971 front brakes onto a 1968 DC. I am installing a booster so essentially, it will be stock, power assisted four wheel drum brakes when I'm done.

My goal was to have an easier supply parts as the bus ages. I have a pair of buses (68 and 72) that seem to have one year only parts. The 72 has been off the road for many years prior to my ownership and I dread not having the parts going forward to accomplish getting back on the road.

Stick with the 1971/1972 front brakes. I have several rebuilt calipers for those years
