Im bench bleeding a dual resivoir master cylinder drum/drum and it seems like the front resivoir has alot of bubbles and a good flow of brake fluid and the rear resivoir (next to firewall) just has a dab of bubbles and doesnt shoot up like the front one? is this normal? Its a new m/c and im using the plugs provided to bleed it, thank.s

typically the front brakes produce 70% of stopping force and has a larger wheel cylinder
the rear are smaller and used less fluid to actuate.

The answer to you question is yes it's normal to see the bubbles when bench bleeding, Just after you run enough fluid through the M/C and don't let it go dry at any point. Once enough fluid has passed through install it and should be good to go unless you let some air get in the system during all this. JMO

eloc, nice car, i was wondering why the front res has all the bubble action and the rear has a little. but i guess its for the back brakes because they need less as stated above..
