Brake proportioning valve

Getting ready to set up rear Musatang calipers from 94-04 Mustang on my '75 MGB SBC conversion with 7.5 Ford rear diff. Front brakes are stock. Any recommendations on a brake proportioning valve?

Thanks in advance,

Brad

Check the Summit, Jegs, & Speedway sites for the ones they sell with their brand name on them. Generally less expensive than Wilwood or CPP but appear to be the same valves.

Thanks Rob. I have looked at lots of options but thought I'd ask here.

Hey Brad
I use Wilwood valves, but I would assume they are all pretty much alike. Just put is somwhere that is easy to get to so you can tune it to your vehicle.

My conversion uses Mustang rear discs and MG std front discs and has a Ford/Mustang proportioning valve like this ebay item. Car stops straight and true and without the hassle of of dialing in a 'manual' proportioning valve.

Brad, you can also use the larger TR8 pads on the front. Same as the factory V8 pads.

Graham,

Any idea of the year/part number of the 'Stang valve?

Jim,

I didn't know that about the front TR8 pads. Thanks. I will be updating the front rotors/pads soon.

Brad

Brad, I'll try to identify the part no and post tomorrow, but aluminum proportionng valve used in Mustang Fox body with disc/disc brakes will work - don't get a prop valve for disc/drum combination.

I hate to start anything, but proportioning valves are specific to each model car. Total weight, weight distribution, wheel base and even tire size effect the amount of brake required at each end. I don't believe an MGB is anywhere similar to a Mustang. Just my two cents, but do some reading on the subject before you decide.

I have had some PM's and some responses here so my research has begun. I appreciate everyone who is offering up their input!
