Re: Dual chamber master cylinder for drum brakes
KULTULZ,
1-There is no brake fluid "flow", only very slight movement. You knew that! 2-"Studying" a modified or custom brake system to match an existing factory system's fixed value PPV doesn't include all the dynamic Hi/Co Lo/Co testing the factory (and I) had to do. I'll stay with, and will continue recommending proven adjustable PPVs thank you. 3-1965-6 Lincolns, T-Birds and Mustangs with front disc brakes. The K/H adjustable valves came in two or three different styles. 4- I hope my advice isn't included in the "puzzling and dangerous" category. |

You can't quite grab the concept. Production braking systems. Sit up a little higher. And, you can use/recommend anything you like. Doesn't make it correct or legal, just (IMO) unless you have a FLUID DYNAMICS DIPLOMA and work for a major car company. Quote:
Let me ask again, how are they adjustable? Quote:
I don't take it as advice. You may, but I find it skeptical.

Re: Dual chamber master cylinder for drum brakes
You too BOB ...
I am really disappointed though that you won't share with me the secret of how the KH PPV (2091) was adjustable. I bet those SHELBY BOYS would just love to gain that little secret. And, it surely would be better than 'SPINNING FOR DOLLARS' (read INCREASED INSURANCE PREMIUMS) with the so-called ADJ PPV, for which there is no real ADJ, only wild guessing without knowledgeable brake spec, pressure gauges and a suitable skid pad. And even then, there is no guarantee it will perform as described. You know, I bet that IS the reason WILDWOOD inserted that WARNING and DISCLAIMER, that being they know too it is meant for RACE CAR and not STREET CAR but would hate to lose the sales. ... sigh ... oh well ...

Re: Dual chamber master cylinder for drum brakes
A late '60's/early 70's Malibu drum/drum master is a near bolt on, may need to drill 1 hole in the firewall. Any dual master you get will make your pushrod a tad short, but adjustable length pushrods are available.

Re: Dual chamber master cylinder for drum brakes
It was what was immediately available locally when I needed one. It worked just fine and is still working just fine per the guy I sold the car to. Improvisation is the very soul of hot rodding.

Re: Dual chamber master cylinder for drum brakes
Over the years and it still will show up on Ebay and other forums as "Corvette" master cylinder I guess calling it that makes it sound better.

What that CORVETTE STYLE ROAD RACING MC gives is confidence in the driver's ability to stab and steer so that the next time he won't go off the road. Much less, it looks good with the DIALING FOR DOLLARS supposed PPV, the INTERSTATE BATTERY, STANT radiator cap (with pull tab) and of course the ever popular EDEL CHI-COM ACL with foam insert that lights up with every backfire. OH! I forgot, also yellow plug wires and a HEI distributor cap. Pop the hood on that baby and all that will set the gang wowing.

Hmmm, need to tell this to Mercury. My '67 Cougar with factory front discs had the residual check valve mounted on the floor pan directly above the rear axle! (I removed it when installing a new master with a built-in valve.) |

Re: Dual chamber master cylinder for drum brakes
Maybe tell MERC you need a SHOP MANUAL. The valve you are referring to was the PROPORTIONING VALVE (2B091). The RESIDUAL VALVE was in the MC DRUM CIRCUIT OUTLET.

Re: Dual chamber master cylinder for drum brakes
I thought that when Ford went to discs in the front they used a combination valve ( Proportioning and residual pressure) and no master for disc/drum setups had a residual pressure valve. Or maybe they came later???

Re: Dual chamber master cylinder for drum brakes
No true COMBINATION VALVE until 1971/72. They were separate before that model run.

The question is, do you have a PPV on your new system? And did the replacement MC come with an internal PRV and how was the new system was plumbed?
