Brake Proportioning Valve ????

OK brake gurus I need some advice.
I have Toy axles under my Zuk and YES VERY good brakes. After all they are 2 or 3 times bigger then what I had. Here's my problem, when I hit the brakes HARD the left rear locks up first causing my Zuk to jump to the left. The braking system is a 1 line system. Now I had a proportioning valve on the tin top with the Zuk axles and it was a 2 line system. Problem is the valve was leaking real bad so I had bypassed it even when I still had the stock Zuk axles.
I'm thinking I need a new proportioning valve and need to split the braking on the rear to a 2 line system.
If I'm thinking right on this let me know and also WHERE can I get one!! [img]images/graemlins/confused.gif[/img]

Re: Brake Proportioning Valve ????

you dont need 2 lines

you just need to fix the valve

my zuk has 2 one at the front and one in the rear

when i did my rear disk brakes. i changed the first valve so it would be the front or rear one one line from the m/c and the other on the other line

and on the rear i really dont know why it's there. i was told that it was like a port. valve then someone told me it was not.

the zuk has a criss cross brake system like one line done drivers left front and pas. right rear
then the other 2 on the other line

i'm running the willwood and have it cranked all the way closed which is 60/40 split i belive and have locked it up the other day doing 45mph it was awsom to have brakes that worked GREAT
