Hi all
I am about to replace the flexible brake lines on by BT7 with the Goodrich braided types and have a couple of questions.
What is the correct way to fit new flexible brakes lines on my BT7?
Should the both ends of the line use copper washers and lock washers?
What is the correct order of the various washers and nuts?
Thanks
Phil
 
One end should be a taper needing no copper washer, while the other end is a flat flange with a thread, and needs a copper washer to seal it.

Fit the flat end and copper washer to the caliper first, or on the brass three way junction on the axle if you are changing the rear hose.

Tighten the connection as this will be the finished tightened position. The taper end then goes through the bracket on the frame.

Slip on a lock washer and a thin nut, but only a few threads, don't tighten it.

Then screw on the acorn nut which is on the hard brake line. Doing it this way gives you a little movement and make it easier to get the acorn nut started, if you tighten up the thin lock washer you can sometimes cross thread the acorn nut as it's difficult to get it started.

Hope this make sense.
 
Thanks Busybrit,
That all makes sense. But on my new Goodrich flexible pipes both ends seem to be tapered! I guess that just means they can go on either way round with the coper washer being used on the calliper end for the front pipes and the T junction on the rear.

The hoses only install one way. The caliper end has a double flare with male tube nut; the chassis end has what is referred to as a "bulkhead" fitting, with a conical end which mates up through the chassis bracket, lockwasher and jam nut to the female tube nut and double flared chassis hard line. A single copper washer is only used where the rear axle hose enters the brass tee on the axle.
