Ok, another (maybe dumb) question or two.
1. I'm running new brake lines on my chassis. My 88 swb I'm building is a LHD but for some reason the previous lines (and bracket for the rear line that meets the flex hose) were on the right hand side (the passenger side) of the chassis. I could switch to the driver's side but then id have no bracket on that side for the rear flex hose and I'd have to screw in new clips all along the left side of the chassis. Is it ok just to run the brake line along the passenger side and come up and across to the driver's side along the bulkhead?
2. I am switching to a dual circuit servo brake system from the old single line system. In the single line system, the rear brake line that runs from the rear flex hose, along the chassis, joins a 3-way junction at the bulkhead, with the brake switch in one of the ports and the line going up to the MC in another. In my two way system, as my brake switch will be on the MC, do I need a 2-way (basically and elbow joint) at the bulkhead still for the line going up to the MC or can I just extend that rear brake line and have it run without a junction straight up to the MC? (I should add, I can't seem to find a two-way junction, only 3-way)
3. Last (dumb) question.. with the front brakes, I have seen diagrams that show a short, hard brake line from the caliper attached to the flex hose running to the bracket on the chassis. But I've also seen the flex hose direct from the caliper to the bracket on the chassis without a hard line. Can I ditch the hard line altogether and just go with the flex line? It would seem almost more practical to do that. But then the question is, do I still use the same length of flex line or do I go with a longer flex line, my concern then being a kink in the line when the wheel is turned and the leaf spring compressed.
Any thoughts would be GREATLY appreciated!

Brake Lines
1. Lines run down the right side on all versions. RHD and LHD.
2. In stock vehicle the lines run through a PDWA.
3. Caliper? If you are using non stock brakes, it would depend on how the disc brakes were designed. On Defender style calipers, the short hard line is there to keep the flex lines in a location safer from damage.
For the stock layout, I would look at the Series 3 parts catalogue. That will answer most questions.

Re: Brake Lines

Ok, I had thought that might be the case but I had seen on some forums where people had stated they 'flipped' the lines for LHD versions seeing as the MC will sit on the upper left (driver's) side of the bulkhead.
2. In stock vehicle the lines run through a PDWA.
I can't find a diagram anywhere showing the layout of this, even for a series 3. What I see is a dual valve MC, with rear line coming down and running to a 3-way junction leading to the front brakes and front line coming down to go to the rear brakes. Then on the actual brake line diagram, I don't see where the PDWA goes??

I am not using stock brakes. Drums on the rears and discs on the fronts.

Looked but can't find an actual layout that shows everything

Re: Brake Lines
OMG what a great setbof diagrams. Not sure why I hadn't come across those already. Some I've seen but some i haven't! Thank you so much!red90 wrote: Sat Dec 28, 2024 12:39 pm Page 1L11

Re: Brake Lines
Still not sure I get wherebthe pdwa is supposed to go. Is it mounted to the frame and does it take both the front and rear brake lines then junction them up to the MC? Again, hard to figure out what goes where.

Re: Brake Lines
The front and rear lines come from the master to the top and they go out the bottom or end to the front and rear brakes.
Mounts to a bracket mounted to the chassis.
It is not mandatory. I’m just explaining the stock system.
