master cylinders, disc brakes '68-'70 B's.....

[hemi68charger]

Does anyone have a GOOD source of remanufactured or new master cylinders for power disc brake applications, '68-70 B-body.. I'm at my wits end with the junk that CARDONE sells. It seems it is the only vendor all the part stores here in Houston buy from. All my brakes seem to be bled correctly, gravity bled and pumped.. No bubbles. But, when I apply them under a load, they don't work. I have to force them as hard as I can for the back wheels to stop. The rear wheel cylinders are new and I have all new hardware. I have adjusted the rears. If all my bleed screws have fluid coming out of them during gravity bleeding, then my valving (proportion valve, etc) must be fine. It has to be the master cylinder. Also, I don't think the booster not hooked up to vacuum will effect the pump bleeding..


Application is my '69 Charger 500

Bill, you talking about the valves; you mean the proportioning valve and safety switch? The link, those are Cardone or Napa units?

The valves on the inner frame rail.
I have had several problems with the Inline tube repop valves



The units I have I bought in bulk, = no boxes . but I think cardone, they are brand new NOT remans.

Although I do have an original OEM casting thats been rebuilt if your so inclined.

Well,, looks like I learn something new.. When bleeding power brake cars, you have to have the engine running when testing. That what it was. I have always rebuilt manual system cars. Even though my Daytona is power brakes, I haven't gone to the extent of this and the motor and booster were already connected. So, as Charlie stated to me, the proportion valve works with power brakes and in my case, it worked perfectly.. So, everything seems to be fine and dandy, thus far.. I have to get the front tires on again and button things up for a test drive up and down the driveway...

Bill do they have the same markings as the ones I posted in the link above?

All the cars I have owned have had power brakes and I have never needed to have the car running to bleed them.  Since then I have bought a pressure bleeder kit and still have yet to run the car when bleeding out the brakes as they always turn out good.

I agree with Bill as I have had 2 bad hold off proportioning valves for the rear brakes.  In Line Tube repro valves suck!!!!!!  Its not a question of if they fail on you, it is WHEN they fail (and usually at the most inopportune time)

Napa lists a reman master under part number NMC P2026. I bought one as a spare it was a new unit in the box. $28.00 I had them slow boat it to florida to avoid shipping. They show 4 still in Philadelphia.

I yanked mine (booster, m.c., prop valve) off a Diplomat cop car years ago. Still working fine and replacement parts are readily available. Not for the factory correct types, but gets the job done.
