I noticed leaking brake fluid coming from just next to the rear wheel arch. Its coming from a box which connected the rear brakes to the front but its not the Brake Load Sensing Valve on the rear axle. Can anyone help me identify this part?

 

[Rich Sims]

Any pictures, a box or a joint, how big?

 

[Yorkshire Devil]

It's bolted onto the chassis

If memory serves me, working from the back forwards - both rear pipes connect to the load sensing valve, there is then a length of rubber hose, which connects to a joint/union which is bolted to the chassis?

Ok maybe it's the load sensing valve. What's the valve on the rear axle?

 

[Roger Fairclough]

It's probably the 3 way connector. Hose from proportioning valve to axle and 2 pipes, 1 to each brake.

There's some sort of rubber boot on it.

It´s 47910-60110.

It's called the "load sensing proportioning valve" and it costs around £200. On top of that you will have the labour to fit it.

As the pipes appear to be copper i.e. non standard, it may be that the connections have loosened a tad. If you are not sure as to what to do, I suggest you ask someone who does to try tightening them for you.

Is it this part which Milners sell? They list it as Brake Load Sensing Valve

What is the spring that attaches beneath it?

 

[Roger Fairclough]

Picture please.

Its called 'spring assembly, load sensing' and the load sensing valve sits on top of it. Part number is 90210-60100.

 

[Roger Fairclough]

Ah yes, this is the rod assembly that connects the valve to the back axle.

According to the w/shop manual you need a serious amount of kit to set-up a new valve. In reality, a decent mechanic can do it quite simply. Ask if you need more info. after you have had the new unit fitted.
