Brake swap

[Ybfav84]

So I’m almost done with my brakes
Do I have to gut the proportioning valve?
And can I run my brakes without one?
Also I was pumping my brakes and no fluid is going down
What could be the issue?

A few more details are needed. What swap are you doing? From what system to what system? What have you changed?

My bad feeling stressed with all this lol it’s a 1984 mustang 5.0
1993 mc
1993 booster
95GT rear end and brakes
Front 04 cobra brakes

Yeah you have to either gut the p valve and run an adjustable one or as I did replace the guts with 94 or 95 innards.

Any idea of where I can buy the guts?

Just got it and install a manual proportioning valve.

OEM combination valve plug:

Brake Proportioning Valve Plug, 1979-2004

www.maximummotorsports.com

Manual proportioning valve:

Adjustable Brake Proportioning Valve, SAE ports

This will allow you to dial the brakes in. Both my cars are done this way and both are a little different on the rear brake bias but stop like a champ.

I appreciate the help
Is that the reason no brake fluid travels down the mc when I press on the brakes?

Did you bench bleed the mc?

Did you bench bleed the mc?

I bought it used, I didn’t smh

I bought it used, I didn’t smh

So you don't even know if the MC works> The seals go out in them... They might look perfect if you take it apart, but they can still be bad....

 

[Ybfav84]

the guy said he didn’t use it
Ig he tried it but ended up going another route

Pull it and bench bleed.

 

[Ybfav84]

Pull it and bench bleed.
