reservoir which one goes to rear wheel cylinders

the one farthest away from the push rod should feed the rear brakes, USUALLY. What is the specific application? I'm a little confused as front is generally farthest away from push rod, is this a retrofit for an under floor MC?

Sounds like you have a MC for Disk/drum cars. The larger side is to supply the higher volume needed for disk brakes. The smaller for the rear drums...

Reservoir size aside, the port with the residual pressure valve, (if you have one), goes to the drums. Some systems do have a very light one to the discs, too. What cylinder is this; and on what car? Mike M.

Normally if you are talking about drum brakes around the front brakes will always have the larger resevoir. The reason for that is cause by the fact that greater part of your braking is on the front drums so the front wheels will have the larger brake cylinders and will need/use more fluid. The back cylinders are smaller and need less fluid capacity.

Vehicle is 1955 studebaker street rod. front disc, rear drum 2 pound residual check and proportional vale on front and 10 pound check on rear. consensus seems to be larger master cylinder reservoir to front disc brakes.

The 'correct' terminology is a 10psi residual check vale and a 2psi residual check valve. The residual check valve is to prevent siphoning of brake fluid when the master cylinder is mounted below the wheel cylinders, or calipers, and to keep a small psi in the line to prevent moisture intrusion, and in some cases, disc pad rattle... The proportioning valve is a different animal. There are the fixed type proportioning valves, and the adjustable type proportioning valves. The proportioning valve is there to make sure that the front brakes apply first, so the car does not swap ends when you apply the brakes. Jeff (That makes the blonde's so mad ) Rice
