What master cyl (stock aluminum)is best for a stock disc front drum rear brake system? Can I run a power master cyl without the booster? Tech tip. If you have interference with roll bar front tubes and your brake lines, the Camaro masters from the 80's and 90's have the lines coming out of the right side.

That's a good question and I don't remember that one being asked before.

To Pickel: do you know what the bore size for your mas-cyl is? I have good brakes but the pedal goes almost to the floor, and i would like a better pedal, pumping them dosent get any more pedal and they are adjusted up.

Go to the parts store and order a master cylinder for a 1979 malibu with out power brakes it should be alu. and have a smaller bore , and the hole in the back of it is deeper then your power assist one if you try and run the power brake one it will take too much pedal effort on the drivers part. The bore is bigger so it makes for a hard pedal .I run one off a 76 chevy half ton truck with standard brakes but it is bigger and made of cast iron (HEAVY). good luck

powerglides, Juni has the right master on his car......the 76 truck 2 wheel drive...
it's a little heavy but has a split bore, which simply means it has a different bore from front to rear.......this is what a guy needs when running disk front, and drum rear.

This is for a disk front/drum rear....WITHOUT a portioning valve

If your rules allow disk brakes in the rear let us know the answer would be different then.........Jeff

this is to awkwardjeff. I am going to disk brakes in the rear this year and you say that there is a better cylinder for this. Which would you use in this situation.
Thanks for any help
