I have been working through the brake lever adjustment process again in an effort to have B14BH stop like the other MK VIs I look after. I have just found a diagram that I haven't seen before but the resolution is poor. Can anyone direct me to a better image please?  . | ||

Where did you get that from ? Here is the link from this forum. You may find that things are not much better, but if you follow the instruction on how to enhance the resolution, it should work. I have not tried the enhancements, so if they don't work, others here will be able to help. I also need a favour from you, I have been doing much work on my car and I have taken apart the rod linkage levers for cleaning and painting. I have assembled them according to the photo, but I am not totally sure if I have them correct. I need you to take some photos of yours at different angles so I can be sure that I have mine correct. That would be very much appreciated. Don't hesitate to ask away of you need help. http://rrtechnical.info/  | ||

That's from the "Early Silver Dawn, Bentley MkVI, Phantom IV and Derivatives" service manual on this site and I'm amazed that I haven't seen it before. I thought I had been through all of the resources here for MKVI. Next time I have one on the hoist I'll get some pics for you. | ||

I found that image, an no matter what I do, I can't get a descent image from these PDF files following these instructions. This is what I get: I tried using a free PDF reader, but that didn't work, the PDF link wants money, it's only a free trial. These PDF downloads do not appear to be high quality as it says.   https://rrtechnical.info/mkvi/wshoplate.html . | ||

I found the free version for Adobe Reader, still no change _ it's unreadable, even after saving the file. The download file from Introcar is a little better, but still unreadable. | ||

Jeff, Carl, if you send me your individual e mails I will forward the pdf of the diagram direct from my workshop manual. Unfortunately after several attempts I have been unable to upload on the forum. Martin B88HR | ||

That would be great, thanks much ! mam.haggis@hotmail.com Once I have it, I will find a way, I think the problem is the file size here on the forum is only 800 pixels square, that just isn't big enough to get a clear scan. A scan of at least 600 dpi would do it, maybe even 1200 dpi. I will find a third party host, even my cloud would probably work and then all I would have to do is share it by adding a link. Probably could even do it with Facebook. Don't know if it could be done with a PDF file with Facebook though, it would be just a large photo, but still should work. | ||

Hi Jeff I have sent you the pdf as requested. Martin | ||

https://1drv.ms/u/s!Ak1aw8qrdXdhtAPNB49cvDrVQWdl Clicking on the link should bring one to the brake set-up instructions and give one the option to download it. Right clicking and saving the photo does not work, the resolution is lost, it has to be downloaded. When clicking on the link, give it some time. | ||

The image is in the Bentley MK VI Workshop manual. The scan is not as good as the original, which itself, does not scan very well. (Message approved by david_gore) | ||

I think it depends upon when it was scanned and what scanner was used and how limited the software was/is. It could have been scanned years ago when the technology wasn't very good. HP scanners and their software are very limited, in some cases one can't even control the dpi. I have a Canon machine and I use that for vintage photo's. I can choose a dpi where I get a warning from the software that the computer may not be able to handle the file size. If I have a good sharp image from an original print, it will be every bit as sharp. If it's a copy of a poor copy, then I can't make a silk purse out of a sows ear. Martin's photo is excellent, the dpi and file are huge, a scanner can do the same if it's in the software's capability. | ||

Thanks Jeff, ithe image was taken with a hand held I pad Pro I don’t own a scanner. The original plate in the workshop manual is in perfect condition which also helps. | ||
| Jeff Martin Frequent User Username: jeff_r_1 Post Number: 377 Registered: 07-2018 |
It's a great photo, and I realize now it would be very difficult to scan that as it would be too large for most scanners. Maybe a print shop ? One would have to take several smaller scans and "Photo-Shop" it all together _ which wouldn't be all that difficult to do really. Just rattling on.  | ||

That's brilliant Martin, thank you very much. There, at last, is the mysterious Fig. 20 to which the manual refers. That makes the job so much easier than using my several dodgy re-labeled copies, none of which are clear enough to easily identify all components. I know at least one Kiwi owner that will reap the benefit immediately. Carl, heydoncarl@gmail.com | ||

May I point you to the KDA132-website: https://www.kda132.com/technical-guide-to-brakes/ EPW-guru Norman Geeson gives there an in-depth guide to brakes setup, even with a few modifications to improve the already very good brakes of these cars. Jonas (Message approved by david_gore) | ||

Christopher Carnley has requested I post the following information on his behalf: "Then there is always the "Parts List", please? If he has renewed all of his brake linings, it will take about 1000 miles before they have all bedded in and become effective. The servo motor also requires attention."  | ||

And this service bulletin where it discusses some brake problems, one of which where pretty much all the slack is taken up between the plunger and the piston in the master cylinder. Category 3A The whole thing makes for interesting reading. https://rrtechnical.info/mkvi/r/bull/7.pdf | ||

If you are still looking for a good copy that will be good enough to easily read all the notes, please provide your email. All of the electronic format manuals I have seen did not scan or copy with a sufficiently high resolution for that specific page. The electronic copy I have I scanned in sections at high resolution from an ORIGINAL 1950 factory book and then I fit the scan sections together to make a very large page. I don't think this website, or any other will post it at full resolution. You need to get it in an emsil. | ||

Carl, I assume that when you say "Stop like other Bentleys...." you are referring to servo lag. Correctly adjusting the linkage is a large part of achieving minimum servo lag. It is also important to set the brakes up properly at the wheels. The key attribute is to have minimum wheel cylinder motion at the front wheels in addition to correct linkage adjustment. The rear wheel setup is also important. When it is all correct, there will be very little motion of the links and minimum servo wind-up before the brake shoes are pressing firmly against the drums. DO NOT use the factory instructions, which for late chassis are incorrect and will have you put the brakes together backwards. Instead follow the instructions written by Norman Geeson that you will find on KDA132.com | ||

Christopher Carnley has requested I post the following information on his behalf: "This is the assembly that Bill refers to as being assembled incorrectly, it is the drawing that is wrong as it is a mirror image. If you take note of the marks made by the stop bar on the end of the cylinder casting, you can see the error." | ||
