1991 MU UCS55 rear brakes

[danieljnicholson]

1991 MU UCS55 imported to the US.
What is the part # for each rear brake caliper?
I could use help sourcing calipers or rebuild kits.
the rear pads are impossible to source here in the US.so I ordered pads of ebay from au and am looking to the future when /if I might need rear calipers since they are not interchangeable with US amigos/rodeos

Are you sure they are different to Amigos up to about 93 or troopers from 88 to 91?
I know what I would be doing if I lived there if thats the case.
I know some Amigos / USA Troopers had Dana diffs but not all. Find an Amigo being wrecked with the Isuzu diff then swap the casing over into yours with whatever brakes it has then fit your diff head into that if the ratios are different. All future problems solved. Plan B would be a conversion to the Dana diff but I dont know how much work that would be.
The disc brake handbrake on your Mu can be a pain at times and was never very good so a chance at an upgrade should be considered

Here is a pic of the rear end and a pic of the required brake pads, what a the make of this rear end?
Need the caliper part numbers and would like to purchase a set of the rear calipers

Any help is appreciated

its the factory isuzu rear diff, you cant buy new genuine calipers i tried, but have seen aftermarket copies on ebay, the brake pads are very common here aroung $20 for a cheap rear set

I rebuilt my '91 UCS55 rear calipers using this kit http://www.ebay.com/itm/310341005329?_t ... EBIDX%3AIT

Got time to start the rear brakes again
Take a look at the right rear caliper
no wedge shaped cutouts on the piston to screw it back in.
are these press in?
do these caliper look familiar, anyone have the factory part #
any ideas?

Standard 2.8 Mu caliper. On the back of the caliper is a 12mm brass bolt. Take this out and you will find a 8mm allen key inside. This it the adjuster. A light pressure on the piston while adjusting helps but do not force it

[danieljnicholson]

ok I got that now. thanks.
Do these pistons screw back in? or once the allen key is backed of you push them back in? is there a manual that goes over this?

How do the rotors come off?

[geeves]

If its in perfect condition the allen key winds the piston back in I always used with my hand at the same time although that shouldnt be needed
Look for my post in the general folder about files loaded to Mediafire. The links for the KB ute are the best match to your wagon

Don't ever use too much force on the adjusting screw. They are a bit fragile. Here are some photos of some of the internal components that you may find useful to understand the system.
