410 Handbrake

[PEU186F]

Thanks Geoff, however your reference brings up the same drawings as I found on the Australian RR site, so I'm no wiser. Further head scratching suggests that the RR callipers might have had an extra lug on the bottom, not present on the 410, perhaps it was attached to that?

However I think that light is finally beginning to dawn. It appears, although none of the books spell it out, that the handbrake cables on the 410 were intended to to be set up to hold the imbalanced calliper(s) off the disc(s) with the handbrake in the off position. I paraphrase the handbook. "In the 'unlikely' event of the handbrake cables stretching (due, perhaps, to desperate attempts to get far too hard pads to bite hard enough to pass the MOT) dive under the carpet under the transmission tunnel and adjust to take up any slack in the cables". What the handbook fails to spell out is the consequence of this 'unlikely' event.

Perhaps thiat will do the trick, I'm not all that confident as there is only one adjuster in front of a balance bar, but it might work if both cables are the same length and there is little friction anywhere, but I will report back, eventually.

Peter, perhaps you might like to try checking touch, balance and adjustment as above, if the 411's handbrake set up is similar

Roger,
Knowing that we are shortly going to have to overhaul the rear callipers on my old Diesel Silver Shadow I did a search about rebuilding them and came across the first two out of three technical videos uploaded for the Rolls Royce Owners Club of Southern California the subject being Corniche rear brake caliper overhaul.
At the start of the first video the presenter doing the work mentions a missing part which he describes as a small 10/32 bolt with two tabs the function of which is to keep the handbrake mechanism centralised, he then shows were these should be positioned. The remains of the scrap 603 don't give any clue as the handbrake mechanism is a mass of rust, as far as I was aware the Rolls Royce and Bristol callipers were the same but I might be wrong.
This "missing part" referred to in the video does not sound like the strap you mention and a quick look on the Introcar and Flying Spares site indicates this is available, part number CD5731 which you probably got off the Australian site. The drawings on the Flying Spares site don't show were this strap goes either and I don't ever recall seeing anything like that when we have being working on the brakes of my cars, then again might be that I was not paying sufficient attention.

Geoff.
