adjustable proportion valves??

[bbcmonte]

I plan to re do my whole brake system. I am going disc brakes all around. With bigger rotors and at lest dual piston calipers. Do I need to replace my factory proportion valve with a all in one adjustable one or can I just a add a adjustable valve to my rear brake lines?

Adding an adjustable one to the rear brake lines would be ideal. You don't need one in the front. Just make sure your master cylinder is the proper size

This is one of the best starting points for a new brake system. It combines a proportioning valve, distribution block, and brake light switch if you need it. I run one on my Chevelle.

Should I use a all in one or just add a adjustable one to the rear brakes

[David LaBuda]

Both accomplish the same task. It just depends how you want to run your brake lines. In my opinion, if you're starting from scratch the all in one unit is the simpler and cleaner way to go.

Thanks, I will order the all in one unit

You haven't specified the application, however you do not want to add a proportioning valve if you already have one in the system, so if the car currently has a proportioning valve of any kind, it should be removed or gutted before you add another one. Two proportioning valves in the same circuit is no bueno. If you do order the distribution block linked to above, Wilwood #260-11179, then I would assume that you're going to be fabricating new hard lines for the car. Is that correct? All of the inlet/outlet ports are 3/8-24 inverted flare, the standard tube nut size for 3/16" hard lines.

Based on your handle "bbc monte", I can only surmise that you may have something from a 1970 to a 2007 Monte Carlo. Even if we rule out the front-wheel drive applications, there are still several brake plumbing configurations to choose from, but we can be more specific if you provide more information.

FWIW, I would remove the pressure sensor from the Wilwood 260-11179 distribution block and replace it with an 1/8" NPT plug if you're not going to use it. The electro-mechanical switch on most GM pedal assemblies is a much more reliable means for brake light actuation and doesn't have the hysteresis (pressure differential between turning on and off) associated with that type of pressure sensor.

I have a 70'Monte Carlo and I going to run all new brake lines

Order is with the bracket

Nice, did it come with a bracket

[gray86hach]

Yes and 1 line I bent the other.

Thanks, I am going to order that kit
