73 Charger Brake ?

[randy73]

I had disc upfront and now added discs to the rear,  do I need to get a portioning valve or do I need to change the MC?

You should have a PV on your car, my 73's did.
Master Cylinder is the same 3461176 power brakes, or 3580184 is for manual brakes. That is the only difference.

Awesome, I will check.

You can see it under the MC in this pic

Also, the factory drum/disc MC has a residual pressure valve (RPV) in the rear brake system that might interfere with the proper operation of the rear discs...depending on the caliper type. The RPV can be removed.

Good to know, is there any way to know without removing the brake line?

wow! didn't know that... do the replacements have that too ?
