Default Front Brake Caliper Plumbing

The front calipers on my 67 340 were off when I bought the car. A friend rebuilt them for me and now I'm trying to mount them. I cannot figure out where all the lines go. I'm guessing the calipers are not sided? The Moss catalog and my workshop manual don't show much. Does anyone have a good photo showing them mounted on the car?

I'm confirming the calipers are not "handed" ie can be mounted either side. The plumbing is the secret with the brake hose connected low and bleed nipple high.
Sorry can't find a photo.

There is a jumper pipe from one side of the caliper to the other. Then the solid hose to a bracket on the shield that mounts to the flexible pipe.

My car has Dunlop Brakes. Girling bought Dunlop's braking interests just after my car was produced. I do not know whether Girling made changes to the front brakes on the 340 as with 420. I don't think they did.

Sorry can't help. Look in the final '72 manual or parts book.

Dunlop - pre touch up & proper wiring with the right tool. Wire Twisting Pliers. Wiring redone after this.









Wire twisting pliers. Worth it as there is much wiring to do on the IRS & diff in my case.

Thanks that helps. I've got the cross over pipes figured out. It's the flexible hose to hard line that is puzzling. The dust shield has a bracket where these hoses join. The problem is that at this point it's right above a port on the inboard side of the caliper leaving no room for a bleed screw. Maybe I'll do a little bending to create enough room.

You might have to do that. I had to do this from straight pipes copying one of my donors. I had a proper brake pipe bender which makes life a lot easier. Bought it for peanuts from Amazon. It's pretty tight around there. I bought a Cunifer brake line kit from Barratts made by Automec. All ready made up & fitted perfectly but they don't bend the pipes for you. All the correct fittings installed but straight or in the case of the long one to the rear ~ coiled.




Brake pipe bender ~ used in many places on the car. This is the same unit I used. Gets the job done. Accommodates 3 pipe sizes.

Thanks again for all the help. I got the fronts on and now if I can find the attaching bolts I'll do the rears.
