Problem with CPP's Hydroboost and adj brake prop. valve

[De-noz]

After i install CPP's Hydroboost Kit I notice some brake and steering problems with this KIT.

I notice that the black adj. brake prop. valve that came in this Kit don't work properly - I can't lock the rear tires on a wet street...I also notice that a small leak at the adj. knob.it self...not sure if this small leak can be the reason.

I unscrew the adj. knob to see what's happened and found a O-ring seal which sits at the knob, question is now ...is there any other internal O-ring or other parts in the black block that's maybe damaged?

I hope the time zone difference isn't too much of an obstacle.


When stopping a car in the wet or any low traction environment, it can be more difficult to lock up the rear wheels. Less grip means less longitudinal acceleration. Less acceleration means less weight is transferred to the front wheels and more weight remains on the rear wheels for more rear traction.
