#1 Brake screws

Post by MLBS3V12 » Thu Apr 05, 2012 11:43 am

Hi all,
I've received the Kit of parts to rework my Servo and master brake cylinder.
However, I want to change also the specific screws used to connect the brake fluid tubes on each assembly. They are all rusty. I dont know where can I get them.
Does anybody know this ?
Thanks for any feedback.

Are you referring to the metal pipes or to the flexible hose connections? If it is the metal pipes, you will need standard imperial three-sixteenths inch ( I think) connectors. Available from most parts suppliers in UK by post . Note, however, that you will need a pipe flaring tool to put the new ones on the pipe because you will have to cut the old flare off the pipe to remove the connector. Check whether it is a single ( convex) or double ( concave) flare before you cut the old end off . If you are talking about the flexible hoses, these usually are secured by jubilee clips

here is a link to a supplier

Hi Michel,

I think it is the brake pipe unions to which you refer. As Christopher has said, these are standard imperial connectors, the standard pipe size being 3/16 inch. Be aware though that one of the pipes across the rear of the engine bay, which connects with the servo, is actually larger, I think it is 1/4 inch. This caught me out when I was buying connector unions to make my pipes, as I did not recognise the fact until too late.

If you are restoring the whole system, the best bet is to replace both connectors and pipe and the best way to do that is buy a complete pipe set, preferably with cunifer piping and brass fittings. The undoubted leader in this field is Automec:

http://www.mamut.net/automec_uk//

I replaced all the pipes once using copper pipe, then found that copper pipe is illegal in Australia, so I replaced them all again with pipes made from Cunifer (a copper-nickel alloy). I have a brake flaring tool so it was cheaper to make them, but if you don't have a tool, best to make a set unless you plan to make several sets (which I have in the past). All my connections and pipe came from Automec (which they also sell separately) and the only reason I made my own was for personal satisfaction and money saving, also I already had the pipe in my garage.

If it is just bolts you want to replace, then perhaps it is better to get as many of the bolts for the project together as you can, then send them to a platers for blasting and zinc plating, much cheaper than buying new, especially for the odd size bolts, washers and nuts.

Regards,

Simon.

Thanks to both of you for these informations. They are going to be very usefull in a few time, when I will rework the brake tubes.
The screws I' m looking for are these ones. They are rusty and there is no more zinc trace. As I rework the servo and the master brake by myself, I also want to get new screws to replace the old ones.
Simon, I am as you! I'm interesting in restoring all what can be and It's also a way to save some ?. It is probably going to take more time !

Hi Michel,

Now I understand the parts you mean. I would try the Jaguar specialists for those, but failing that, I would get them plated. Alternatively, you might be able to get the parts from a company which rebuilds servos and master cylnders. Problem there is that they may keep them for themselves so they can rebuild the items and may be reluctant to sell the individual parts. Incidentally, the unions in the upper pictures are called Banjo bolts and a quick search on Ebay revealed this:

http://www.ebay.co.uk/itm/7-16-x-20-UNF ... 27bbc74260

It may not be the exact item, but stainless steel would be a good option and they might have other sizes and similar unions.

An option I forgot to mention is that you can set up your own plating at home if you wish, I don't know the best places in Europe to get the kits, but they are available.

Good luck searching,

Regards,

Simon.

Hi Michel,

Get them re-plated in zinc. If you are undergoing a major rebuild throw all of the fastners and fittings in a bucket and take them for zinc barrel plating. Fasteners are generally finished bright zinc, parts such as door catches were often given a gold passivate, check the originality guides for this. Re-plating will save you a lot of money and add value to the finished car.

Good luck with your rebuild,

Kevin
