Overhauling brake master cylinder

Failing that, if you have a PBR wholesaler they should sell the PBR rubber grease in a 150ml tube.

Yes - and Rolls Royce changed fluids somewhat later than Citroen. The main difference between the Rolls Royce and Citroen setup was that Rolls Royce used coil springs not hydraulic accumulators to provide the actual springing - did on the Silver Shadow anyway, don't know about after that. I believe they actually made most of the bits themselves, but paid royalty to Citroen, and probably bought a few bits from them as well. JD (Owned Citroens for thirty years, still have a DSpecial)

Got a big tin at work from the autofactors a couple of months ago, I've also got silicon grease.

Citroen's power braking system was bloody good, IMHO. The cunning suspension was neat too, of course. I had a couple of BXs and also occasionally drove a mate's CX.

Totally agree. I had a BX (1.7 diesel - the slowest of the lot) and it was one of the best "cars" I have ever had. Totally reliable and gave 50mpg no matter what. When it failed its MoT on suspension pipes and spheres I was happy to pay £600 to put it right, on a car that was worth little more than that, just to keep it going.

Can you do me a favour and read the leaflet - Delphi/Lucas was the one where they couldn't guarantee that it was ok for rubber

- if they are now saying it ok that would be good.

I just phoned the shop to check and there is no warning leaflet in the box the sachets came out of, he's confident it's for use on brake calliper seals etc and they (BL Car Parts in Scarborough) are very well known and trusted in the area. Googling for it only confirms this, although the maker's web site is sod all help apart from a phone number.

Incidentally there's no mention of Lucas being involved, it's Delphi Lockheed, and although I have no idea of the corporate structure I would choose Lockheed name over Lucas any day 8-).

The point is the brakes and suspension are integrated. On the DS at least the braking force is distributed front to rear according to the instantaneous weight on the front and rear wheels; the brake pedal has zero movement and is closer to the floor than the accelerator; and you have about thirty applications of the brakes after the engine stops. Add inboard front brakes, centreline steering - and then remember this is a 1955 design! JD

Thanks for that.

Lockheed was part of Lucas, the brake and diesels disivsions (and some other bits) being bought by Delphi when TRW realised they had overstertched themselves buying Lucas.

Lucas had always maintianed the Lockheed name, as they did with many of their divsions, though in later years the idea of Lucas-Rists, Lucas-Diesels (nee Lucas-CAV) etc crept it. I don't think many people realise just how big Lucas was - it was in the top 6 global automotive (and aerospace) suppliers. It was broken up and sold off for tuppence halfpenny to keep a couple of London pension fund mangers bonues up.

Lockheed stuff is slowly being re-branded as Delphi, i.e the word "Lockheed" is getting smaller, while "Delphi" is getting bigger. Delphi is the aftermarket name for General Motors, or one of the big American names, I can never remember which.

Oddly, TRW started dual-branding Lucas stuff (they largely ended up with the electrical stuff - less Marelli) with the green Lucas name and red TRW name making the boxes look like Christmas decorations, but now seem to have reverted fully to the Lucas name - touting themselves as as a one-stop shop for the trade.

Richard - e-mail with pics is on the way.

AC Delco is the GM aftermarket brand.
