Can't help with the torque I just do them up with a decent spanner or socket on a ratchet tight but not overboard I don't use loctite and haven't pulled any Down that's had it but really it couldn't hurt
Can anyone tell me, or hazard a guess to the Torque value I should be doing the caliper bolts up to? These are the bolts that join the 2 caliper halves. They are 7/16 UNF thread. The caliper body being some sort of cast steel? I will also be using some form of loctite.

The heat generated will probably kill Loctite, but if you are going to use it, use 272 as it has the highest temp rating of the 'undoable' ones (+200*C)
BTW, there are charts listing the appropriate bolt tension for various HT bolts in each thread/pitch.
Ok, so is loctite good practice in this situation? I thought I could see some residue on the bolts?? They are grade 5 if that helps.
I'd use it.
Hang on, I remember now that I always did on the race cars, and they were steel bodied Lockheed's too (but twin piston)
Well I finally got them back together.....All went pretty straight forward. I tried the intsall method in the seal kit instructions, that is:
install seal
install piston
install wiper seal in wiper seal ring
install wiper seal and ring to caliper
I had trouble doing this, so on the advice of a memeber here, I went:
install seal
install wiper seal in wiper seal ring
install wiper seal and ring to caliper
install piston
I used plenty of brake fluid on everything as the lube. It was very easy for me to do the ring and pistons as the calipers where halved when I did so, so access was good.
Wrong or right I tightend the grade 5, 7/16 UNF bolts to 50 ft/lb, using loctite 272.
I really hope I havent cross contaminated anything as the only way im going to know is when they are fitted up to the 110.

gallery seals: 3851-739 (front) RTC1137 (rear)
pin/spring kits for pads: STC8575 (front) PFK1601 (rear)

good job serge

The Isuzu 110. Solid and as dependable as a rock, coming soon with auto box😊
The Range Rover L322 4.4.TTDV8 ....probably won't bother with the remap..😈
I allways fit the piston first then the dust seal but if its worked for you that's great. Biggest issue is getting the tin ring that the dust seal sits in to go in square with out bending it looks like you did fine to me
As I allways say there's more then one way to skin a cat . One shop I worked at for a few years used to make all the apprentices spend 6 months with each tradesman just to show them there's more than one way to get a job done right and I think it made them better tradesmen by the end of it.
