Outer Limits 4x4 Board

Can someone send me (or post) pics of the 4 channel brake master cylinder please.

If you are doing this in preparation for ETC - you do not want to replicate the Range Rover brake system (which is good but very complex). The Range rovers have a dual circuit system - one circuit consists of 2 pots each of the front 4 pot calipers, and the rear calipers, the second circuit is the other 2 remaining pots of the front calipers. Because of this system they have 2 flexible lines to each front wheel. However I think that they just have a normal dual circuit MC.

If you want to upgrade the brake system in preparation for fitting ETC - you just need to have a basic dual circuit MC and a separate brake line to each wheel.

If you already have two separate circuits on the front then you can split the rear into two circuits pretty easily.

When I did mine I got a four way adapter off a late model disco
and used that to run the line from the MC into and then two outputs - one to each rear wheel and then blanked the other two off for the time being.

They are needed later to connect to two slave cyl for traction control.

Yep, getting ready now (much to the other halfs winging "more wasted money"... she just don't understand)

Current setup is a splitter on the MC up to another block. From there, one line to each of the front and a single to the right rear (where it then splits off to the left).

So you already have one line to each front from close to the MC, you would just need a 2nd splitter block for the rear (mounted near the MC), and then to run 2 lines, 2 flexible hoses, and a single line to each rear wheel.

You wont need to run an extra rear line the full length of the vehicle. The current line that runs to the rear can be split into 2 at the rear.

Are you sure????

The Traction control boosters can be mounted on the rear axle if you want.

The boosters dont have to be mounted in the engine bay. Its just usually easier that way. But with a ute it would be just as easy to mount these under the tray. So it would only need a short section of line made up after splitting the single line.







Yes im sure

That is how mine is done, the cyls are above the a frame ball joint, just before flexi hose comes down to the rear axle it is re-directed into a 4 way connector and then send back down to each rear brake via an additional flexi hose.
