question about bleeding the front brakes? (drum) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

novice question here..ive got a 69 and ive got the entire brake assembly off because im going to discs. On the passenger side the fluid is all drained out...you can see the hole in the bottom of the master cylinder. The other side of the car I took the brakes off the same way and im not getting any fluid to come out..doesnt matter if i press the brakes or not. One section of the master cylinder is still full...what gives?

Not sure what you mean. The master cylinder is devided into two circuits Front/Rear and not left /right
You shouldn't have to bleed the system untill you have all the new brake components hooked up.
Also keep in mind that you will need to swap out your master cylinder from your drum/drum to a disc/drum unit.

you will need to add a proportioning valve to your new disc/drum master cyl as that 69 only has a distribution block
