Did it a couple of years ago, I think the calipers came from a 155 turbo, pad size is a little smaller than the sierra, but weight is lower. I looked at the rear of the Murano? Weekend and I think they would fit as well. The design is very similar as I think they are made by the same company 'Lucas" (Valeo?).

We used Alfa/Fiat calipers, cast ali, a bit lighter. Still made by 'Lucas" Tried VW Golf but were too big to fit inside 'our' 13" wheels

The Sheds - always at the cutting-edge 😬 regards Naomi

I've never seen so many fowl comments regards Naomi

Both our sevens have the rose joints and so far no negative effects. One has been fitted with this ca 4-5 years?, has ca 160bhp, LSD and uses ACB10s mostly trackdays (Le Sept), Second fitted 2 years, 135bhp, LSD, 032/048 more sedate trackdays and road. Former has rose jointed dampers, a good idea, latter not yet.. Having said that I hope the cars survive this years Le Sept!!

Hug a Heinkel 🤔 😬

LIve axle? do you have drums at the back? If you do, could these be a contribution to the fade effect?

The density of isocyanate is 1.23 and polyol 1.06, very important to get the information whether the instructions mean 50:50 by weight or by volume.

I would suggest increasing the isocyanate (the brown component) by 5 - 10 %. Do a couple of small cup tests to to see if there is an improvement. The anaorak bit ? the polymer is not stiff enough to resist the natural shrinkage of the expansion gas during cooling, or some of the cells are not bursting to release the gas at full expansion (soft foams). Increasing the iso component should cover both these issues. I would also pre-stir the other component to ensure that there is no separation of the mixture. Temperature of the components might be a factor, follow the recommendations. A bodge could be to inject air into the areas that have shrunk opening the cells, this however might result in a softer seat than you need. If the foam is fairly stiff this will not work. Good luck and don't forget to wear the protective clothing.

As said the amount of catalyst is fairly important. The resin has sites along the molecular chains where cross-linking reactions can take place. The catalyst sets these reactions into motion. As with most chemical reactions the speed is temperature dependent ( even starting materials ) and the cross-linking accelerates if heat builds-up, hence the smoking comment above. Most polyester resins have a small proportion of a wax like material that migrates to the surface. This protects the reaction from the air which retards or stops the cross-linking. This may not be important to know except if you are putting new resin onto old. The old surface needs to be removed or poor adhesion is the result. Polyesters are quite to very brittle, they are only the glue to hold the glass. The strength comes from the glass, the higher the volume content ( of glass) the stiffer it is. ( A big generalisation, orientation etc comes into it, and don't mention carbon )

Which tyres and approx how much power do you have this is also relevant.

LED rain lights are sold for racing, would these be a solution? I noticed someone advertising them on racecardirect.com for 25ukp http://www.racecarsdirect.com/cars/details.asp?id=18853&cat=0, Lifeline do square ones for 68!!! Brightness should be ok, if not too bright.

If Roger is who I think, Schaffhausen area? we could help with transport for a suitable contribution to NtL. See locations...

The reason I would change to discs would be that it is difficult to find a durable brake lining, mine get hot and fade quickly. Suggest you look at the Alfa/Fiat calipers, we found that they have similar fixings as the Sierra but smaller and lighter. Made by Lucas as many others... who ever Lucas is these days?

Not any more I'd say.... regards Naomi

Not an expert but does the piston area relate to the effort/feel so if you remain with same piston area the brake should feel similar, there are probably some geometric factors related to multi cylinders but have not calculated it!. However isn't the idea of 4-pots to get greater pad area, and as has been said spread the load more effectively? The question is then if you go to 4-pots do you get greater pad area? If so then would this increase braking? I have changed the orginal calipers for the Alcon 2-pot set, the braking is similar as I have retained the same pads.

If you decide to drill a hole I would suggest using a bit of araldite to seal the exposed fibres.

You have mail re: diff.

June 1963 in a Cortina Mk.1. I think the school uniform helped 😳 regards Naomi

I think there is a speed limit for studded tyres. Not much of a problem on ice and snow but if you are travelling from Crans to the Simplon I think you travel through the Rhone vally which is for most of the winter snow free, or the roads are clear. Studs are normally put into winter tyres so I would start with winter tyres and go by train if bad weather is forecast. Fill the boot with sand will help. Consider leaving your car in Brig and using the Swiss rail network ( they are on time ).

You've cheered up then..... Many Happy Returns for yesterday Edited by - deanteam on 28 Oct 2004 07:59:39

Getting bitter and twisted, Dan 🤔 😳

Maybe only hydrogen sulphide.
