Brakes: master cylinder change

[ozrod]

After reading the tech help in the April TW about using the Dodge Dart M/C in the 66 Daytona I thought I would try it on my 65 Cruiser with power disc brakes. My question is which
part of the reservoir feeds the front or rear brakes?

[dave hethrington]

The big reservoir feeds the disc brakes

[StudeRich]

The Reservoir closest to the Push Rod Always feeds the FRONT Brakes regardless of their Size.

The Same Size Front/Rear Master Cylinders are for DRUM Brakes.

Not to argue but I am pretty sure that is wrong. You need more fluid for the disc brakes as the calipers have bigger pistons requiring more fluid. The drum brakes need a residual valve to hold a small amount of pressure on the drum brake cylinders. Drum brakes will have the same size reservoirs. Have been in the business over 50 years. I have made a mistake once (joke)

You two are saying the same thing.

I realize that Roy, but my Point is: what if there IS no Large and Small Reservoir? We have NO idea WHAT Dual Master he bought, Disc or Drum!
This way, it is clear to everyone else reading this also, which is which, get it?

You are correct though Roy. I was responding to Post #1 and #2, I have No idea why Dave posted again saying exactly what I said.

[dave hethrington]

Because you said that the closest to the push rod was always feeding the front brakes. This is not actually correct as far as I know. Pretty sure some have the front reservoir bigger which is for the front discs

Sorry for the confusion. I should have stated that the TW article used the Dart drum brake MC which I purchased. The rear reservoir (closest to the booster) is slightly larger in volume.

The section of the MC that has the LONGEST stroke always goes to the front brakes......

I would have to agree with you...case in point, a 1971 GMC 1500 master cylinder, the front reservoir feeds the front brakes. cheers, Junior
