Just for clarification. The calipers were already clearanced from the 85 axle before fitment to the 97 axle, but I didn't check to see if the prior mods were needed either.Quote:

Nice build thread, by the way, Grimace. I need an office job so I'll have the time to read all these things.
There is no need to sleeve any bolts. All bolt holes are clearance, the load is taken by friction and the bolts are there to provide the clamp load.
All true for most applications of course, but did you read the link Grimace put up? It sounds like Skiboy did it all correctly and they still came loose. I think brake parts tend to be a bit different as they have such large forces on them.
I actually lost a bolt in one of mine. Not because of clearance but because I didn't torque it up properly. I put a torque wrench on it, tightened them evenly and it gave no more problems.Quote:

Next time you're in a steel framed building, think that every bolt that holds it together has at least 2mm clearance.
Now I'm a little confused, doesn't the '83 rangie have dual pipework to the front while the Defender has single pipework.
On my '85 Rangie we went the simple route and fitted the callipers and ventilated rotors off a '92 Rangie. There was a noticable improvement in the braking and no need to change the plumbing.

Yes the rangies have dual pipes. It's only a re-plumbing exercise to revert them to the front/back split that every other car in the world uses. The problem with the dual circuits to the front brakes from a safety perspective is losing one corner (burst rotor or sever both lines) and all brakes are lost.Quote:

My hybrid has dual pipes going to the front callipers. It is a '81 RRC chassis which originally had a dual circuit system. At some point they join as the master cylinder is a single circuit system from a '81 SIII Stage 1.
Is that of any help?
yes, dual pipework on all rangie classics, Just fit later (1990 on) calipers and rotors :)
