Hi All, the most sensible way to reline Brakes is to take all 4 drums a shoes to your nearest brake firm that will skim the drums and bond on new linings they will then grind the linings to the correct dia of the machined drums.
and when refitted will need very little bedding in ,
Don't waste your time on Micky Mouse Solutions
This bound to get a reaction

Yes indeed it is Colin, firstly you need to ensure that your Brake Firm fit soft bonded linings as many don't, secondly I fail to see why you would consider correctly riveted and fitted linings to be a Micky Mouse solution. I do however agree that if you do not have the skills it is better to entrust these jobs to a competent person. That said I have recently helped several different owners with issues caused by incompetent specialists

HI Ian, I am not saying riveted linings are M&M just how they are adjusted to the drums , most drums will benefit a skim which makes for a much better end result

On moderns the shoes are free to locate ion many directions so radiussed shoes are fine. But the pivots and cams on a Seven are fixed. Better to leave material so linings can be fitted to accommodate all the variables in pivot location, shoes variation, cam contour etc.
To conserve lining some adjustment of the bearing points often desirable, as per other current post.

Because rivetting is not economical for mass production and now not common it is often regarded as poor practice. I have seen more detached glued linings than rivetted ones. Seven linings can seldom be exploited to the backing anyway.

Skimming drums is fine on moderns where the adjustment or hydraulics take up the clearance and new drums often cheaply available, but needlessly increasing dia adds more complication with Sevens. Steel drums are too thin to tolerate much of.

Hi Bill

I presume your barb was directed at me in your customary manner.

Your perception of gobble****ok does not seem to match the MacQuarries dictionary definition.

I am ever eager to learn. If you would apply your considerable writing experience and demonstrate to me how the ten or so points made in my post could be presented more succinctly with fewer words I would be very appreciative.

If any points are unclear it is because some express disapproval of full explanations.

My post was not unsolicited. Colin did ask for reactions. Maybe he was serious and maybe he was playing games, but after your response no one dared continue.

And on the topic...
I am familiar with the very elaborate instructions for cleaning cyls after honing, and am always concerned about abrasives remaining after use in any soft material. So I always fitted linings by filing. My main concern now is that with 50 years elapsed, the gestation period for asbestosis is still at least another 20 hence.

Bob - my Oxford dictionary describes the word as pompous jargon. A most respected member had only just taken you to task over your verbiage, but you went straight ahead with more unnecessary guff. Please don't imagine that he and I are the only ones who feel this way. And don't blame me if your posts get little or no reaction. A good example recently was when you started a post similar to one already there with practically the same title. The original one gained over 1,900 views with 63 replies. Yours brought 421 views but only 2 replies - and neither one was from me. Say no more. Cheers, Bill in Oz

Hi Bill

The number of replies is not a measure of the usefulness of a post. If a post is providing informationn and is complete there need be no reply.

One probem with reasonably complete replies is that persons using the Search facility need not ask at all, which makes the Forum seem dead, although useful to newcomers.One justification I suppose for limited cryptic responses.

The basic fact is that with the system of fixed pivots, fixed position cams, and non floating shoes on Sevens, radiussing with sandpaper or whatever on the car is more likely to obtain an immediate good bedding than shoes radius ground off the car.

In the post in question what was pompous and what was jargon? Perhaps I should have said "worn down to" instead of the big word "exploited". I would still like to see how you would have worded my post.

Bill, you won't get anywhere with this. The man suffers with a acute case of literal diarrhoea.

Hi Bill, As you will have noticed bob was of on a tangent on is last post, also saying that I might be playing games.
What I was trying to get across is that there is no need to use doubtfull methods when it can be machined properly.

Ps,I served my time engine reconditioning in the Late 50s when white metal bearings and mechanical brakes were still around,and have been involved in Engineering ever since

I LOVE it.....keeping our heads down, here in the Mother Country, watching all you Colonials slug it out.

Not sure Vince Leek and Ian Dunford fit the description of colonials ?

Vince et al. The only reason I've become involved, when others have given up trying for a couple of years,is to hopefully eliminate everyone having to plough through excessive and irrelevant nonsense to find when/if Walter Mitty has made more errors. Most have advised me to ignore his submissions as they do, and I would have taken that advice but for one important thing. The number of times he's given incorrect/out of date information is legion and this is a danger to newcomers. These newbies don't need expensive mistakes and the possibility of losing interest in Sevens. Be assured that even when our friend has not been corrected on the Forum, the enquirers have been contacted directly via email to steer them out of trouble - and I've been made aware of plenty of examples. My main problem now is the time taken to read the emails of support that still keep coming in! Apologies for the lengthiness of all this.
Tony - I have an A7-related magazine photo of a bearded man trudging down a road with the caption "The wild Colonial Boy". It looks suspiciously like Ian Dunford to me!

Bill,

Tony - I have an A7-related magazine photo of a bearded man trudging down a road with the caption "The wild Colonial Boy". It looks suspiciously like Ian Dunford to me!


After re examining the pictures I have of Ian - I think I have to agree- Ned Kelly would be envious!

But Bill, please look through this thread.... You have actually increased, rather than eliminated, the irrelevant nonsense. Leave it alone. If you don't like someone's comments just ignore them, please.

Sorry Andrew, but I can recall only two supports for Bob's irrelevancies. And both of them are from you. Cheers, Bill in Oz

You are missing the point Duncan, Bill and others make some very valid comments about many of Bobs postings being wildly misleading to the uninitiated seven owner. Yet for trying to highlight this to newer and less experienced owners they are being portrayed as the bad guys! Would you rather these comments are left to stand and trip the unwary? I myself have tried to ask Bob not to make his opinions and theories sound like they are a statement of fact, something Bob has chosen to ignore. At one time I thought that Bobs comments were simply the blinkered, misguided, opinions of a man who had bitter memories of running a worn out seven on a shoe string in the 1950's. I now believe that he actually relishes stirring the pot and trying to get a rise out of the likes of Bill, either way I see it is damaging to the forum. Which is a shame Bob obviously reads a lot, and could probably contribute positively if only he could refrain from all the bigoted BS.
