Is it possible that one of the calliper pistons is stuck/seized in the cylinder bore for some reason and there's a slight gap between the piston face and the new pads?
As you've fitted the shims and springs correctly then I'm really not sure what else it could be. I suppose that given the extent of the work carried out you may have knocked or misaligned something? Given the potential risk, it might be worth getting the wheels off again and checking all fasteners for tightness. |

Were the pads too loose when they went into the caliper.
If they were they're rocking in the caliper |

Wouldn't the pistons take care of any gap pretty smartly after the first depress??
>>edit, I see what you mean now... rocking on the other axis... good point Was going to suggest the rotor has runout issues (it's not on true), but if it's only on rough tarmac, that puts that theory to rest (yeah?). I'd say just open it all up again and check it's still fastened to spec. Check runout anyway if you didn't. Solved the bowel problem, working on the consonants... |

Did you check for play at your wheelbearings? Roel

It is very normal for the rear pads to rattle in the caliper. I am sure that there have been many threads about this in the past.
If thsi is the source of your rattle, it isn't harmful, just incredibly irritating! |

Thanks for the replies.
It's a high pitched tinny rattle. The anti rattle shims are held on by the pins that hold the brake pads, and have a C shaped hole in them, are they fitted with this hole to the front, or to the rear? Maybe l fitted them the wrong way round. There were no instructions and the old calipers did not have the shims to compare. |

It seems these are anti squeal and not anti rattle shims.
I took it apart again and put copper grease on the sides of the pads where they slide on the caliper. The noise stopped for a few miles then came back. It seems the pads are not a snug fit in the calipers and there's also a bit of play at the pins. Calipers and pads are Britpart XS which are supposed to be their premium range. |

I think you may just have identified the root cause! |

Likely it's the 'premium' noise you're heading.
FWIW, no squeals from Ferodo pads in my recently rebuilt calipers... Solved the bowel problem, working on the consonants... |

Yes l had to remove the hub to fit the new discs. |

TD5 has two not system huh? (Not stake nut)
I guess what Roel is asking is did you set the axial load on the (taper) bearings 'properly'? (Inverted commas as there are a few ways to do this in the various literatures, official or not) They need a fair bit of load, doing it 'by the book' in my case led to hubs with more friction than I expected, but driving they appear spot on once wheels are on (no heat build up)... Indicating to me that setting g them 'nice and spinny' when it's just the hub may lead to loose bearings once the extra sideways forces of the wheels are applied (over rough terrain) Solved the bowel problem, working on the consonants... |

Original a td5 has a one stake nut system with a spacer between the bearings. Mine has not anymore as I had a little bearing play and changed to the old 2 nut system.
But when you replace the discs and probably bearings too the original spacer should be the right size but why does Land rover supply diiferent sizes? 
What I wanted to point out is that if you have some bearing play your pistons will be pushed in further and the pads have more space to rattle.
