Brake problems

[jthedad2]

I recently purchased a 1972 N600 Honda and I am a little dissapointed in the brakes. I have been looking around for info and I am a little confused about my options on improving them.
My car does not have a booster. I read where their were 3 different boosters available for this car. Not knowing what has been done before I got the car, I was wanting to know if all 72 AN600`s had a booster or if it was available without one like mine.
Also,there are 2 different master cylinders available, 3/4" bore and 13/16", was 1 used for power and the other used for manual brakes??
The car does stop, just not well , even when I apply a lot of pedal pressure, I just don`t feel brakes are safe enough for a panic situation.
If an upgrade to a later master cylinder without chopping up the car, what do you recommend??
Appreciate any info,
Thank`s,Jeff.

Many years ago an engineer who owned a 600 came to our warehouse to buy a few bits and pieces.  I will not characterize him as some one who did not want to pay anything for the things he needed, but yes, he was a bit tight.  He was particularly upset by the cost of a booster diaphragm,  His solution was to get rid of the booster!  He thought that by changing the pedal leverage, he could equal the performance of the booster.  Yea, right!  He thought I should tell everyone that this was the hot tip.  Yea, right!  The problem for me would be some sort of liability.  Not me, than you very much!
Any way to your problem.  You need more than a booster.  You need brake lines, A vacuum check valve for the intake manifold.  Booster and mounting plate.  And then there is the master cylinder.  Best place to start would probably be with a donor car where a matched set of pieces might be found.
The late sedan used two different boosters.  Both have an aluminum body.  The first has the breather mounted below the cylinder.  It was used from chassis 1033852 to 1049184.  After that, the breather was mounted above the cylinder.
Good Luck, Don

Has anyone tried to mount a different brake caliper (maybe from an early civic) that would house larger brake pads to cover more surface when stopping the rotor/wheel? I know it would require lots of work, but to me it would make since to attempt the mod for a more modernized brake system.  Crazy thought or what?

I got a yellow one too. The brake boosters on this year are noted for going bad, looks like this guy just took it off. You can get one from Ebay  for about $60 and have it rebuilt. If you would like my contacts let me know, there are good people out there willing to help you.Mark

Was able to come up with a booster for my car, would like some contacts to get it rebuilt. Have a couple of questions on how to plumb this booster. I have an in and out port on this booster how do they plumb to the master cylinder?
Thanks for your help

Jeff,
The brake line on your mastercylinder will be moved to the outlet port on the Booster. And a new line will go from the master cylinder empty port to the inlet on the Booster. Don't forget the vaccum line and check valve to the intake manifold.
