Brake lines

Post

Back to the top
So I'm running a non servo set up. The MC has only 2 ports so I'll have to run splitters on the lines.

Any suggestions as where to split? I'm thinking one port to front brakes and then running a single line to the back and splitting it at the back.

Vw11 calumets up front and drums on the rear.

Any thoughts?

While that would work, with one line to the rear you would lose both rear brakes if an issue appeared, that the original split system was designed to overcome.

That's what I was wondering abfmk1


 So split them earlier then is the suggestion?

Yeah, I believe the front orifice would be split (for example) front right/left rear and the rear orifice would be the opposite. So in the event of failure of one you would still have a front and rear brake working, but to be honest in a car that's not covering loads of miles a year, with regular maintenance I would think failure pretty unlikely and do your first suggestion. Do you have the rear compensator? which requires 2 lines or do you have the ones that screw into the master cylinder?

I thought that was how they were originally run. To be honest though I'm thinking along the same lines. I'd almost rather have a failure of either the front or the rear, at least that way it should stop in a straight line. But that being said the rears are never great with drums as we all know!

I don't have a rear compensator tbh. I'm thinking that the lack of 'strength' in the rear drums will be enough on it's  own. I'm pretty sure the Cabby doesn't have one nor does my Derby as far as I'm aware. It might be a case of suck it and see, although advice is always welcomed!  :thumbs:

Diagonal Braking has been around since the 50's.
The Cabriolet has the Proportional valves on the MC, for the rears.

I personally have had the Brakes go out on me and I was very thankful for the e-brake.

The rears don't have the stopping power that the front do, but, having no front's isn't fun at all.  

I had a rear Brake line fail on a MG as I was going over Rail Road Tracks…. then at the next stop, no brakes….. a broken line isn't fun… E-Brake…….

On the Westys, the Proportional Valve was on the Fender, and split the 2 lines to 4.  You might look on ebay.

Replacing all the Rubber hoses with the Stainless Steel Jackets ones that have the Teflon inners ROCK….

What do Divorces, Great Coffee, and Car Electrics all have in common?

They all start with GOOD Grounds.

Where are my DIY Links?

Strange no proportional stuff on mu cabby ar all. Very odd.

Yeah brakes failing never good. Yup thinking of going with braided flexi lines.

mk2 have T pieces on the left side where the brake lines to the rear poke up from underneath

the mk2 brake beam mounted bias valve can also compensate for the loss of one of the brake circuits as well, not sure if the older mk1 unit can do the same
