Return PolicyThese proportioning valves are similar to what GM used on many cars in the 70s. They are non-adjustable and may require an adjustable valve in the rear brakes (if needed). Block incorporates metering (for front brakes) and proportioning (for rear brakes) into one unit. For use with four-wheel disc brake systems.
Includes hard lines to connect to a master cylinder with 1/2"-20 and 9/16"-18 outlets.

Customers appreciate the easy installation for our product, the brake proportioning valve, as well as its perfect fitment for both front and rear disc brakes. Its high-quality design, efficient performance, and superior functionality, particularly in conversion work, are praised. Some buyers had to make multiple attempts for a leak-free setup, but the product's compatibility with various car models and its usefulness in disc/drum conversions received positive remarks. Despite requests for alternation in the pedal design, the product overall inspires repeat purchases owing to its reliable performance and effective proportioning pressure. The product is esteemed for its resemblance to OEM parts, offering swift installation and optimal results.

This proportioning valve has two outlets for the front brakes. Are these both to be used (one for each wheel) or be used as one or the other?

I have this same valve purchased thru MP Brakes. I have NO PEDAL after bleeding the brakes 5 times. I have a new master, with plugs in it, the pedal is at the top. My valve is mounted sideways, should this make a difference?

I went from drum to disc in the rear of my 69 nova. I purchased this proportioning for the job. Every time I try to bleed the system the valve flips and I get no fluid to the rear of the car? Any ideas for me? I have tried to gravity bleed the system as well and bench bleed the master? Any help would be great. Thx
