this time is my turn about THIS brake problem

[Nacho-RT74]

A friend of mine has had this problem since... we can't rememeber how much time ago.

the front brake fluid deposit ( rear brakes ) is getting emptied for a while the rear deposit ( front brakes ) is overflowing. Of course I'm missing brakes power

Please your thoughts.

My friend has changed master cilinder three in a row ( in a month ) with same results.

I have changed piston seals once I got that sympthom the first time and got fixed just for two-three months.

He ended changing the brake fluid distribuitor bloc for the GM kind, but has not enough brakes.

Please tell me THERE IS NO CHANCE that dist block got damage making fluid flow inside block from one deposit to another throught brake lines.

if this is the problem IS THERE SOME CHANCE TO GET A NEW dist block ?, maybe aftermarket but exactly to original with integrated prop valve ?

you can eliminate the dist block by hooking the front brakes up direst with a T to split side to side & use an adjustable propotioning valve in the rear line , you will lose the brake warning light though

Sounds like a proportioning block problem

Sounds like a proportioning block problem

proportioning block or distribuitor block ? Proportioning valve is part of the dist block... could it be just the proportioning valve damaged ?

with this problem my brake warning light has no turned on
