Front disk brake conversion on a '63

[Ruud Z.]

I consider a front disk brake conversion on my '63 with KO wheels. I regularly drive my car (fast but carefull) on nearby tracks and my drumbrakes just do not provide enough (safe) braking power when there are heated up after a few laps. I do know that under normal circumstances there is absolutely no reason to change to disks and I do know about the downsides (leaks, etc) in relation to disks and callipers. I am looking for a bolt-on conversion(-set) with NO offset which fit my KO-wheels and a dual mastercylinder and powerbooster that will fit under an original '63 hood without (major) modification. I just cannot seem to find a supplier that incorporates everything in their products. Any help is appreciated.

Ruud,

I installed a '67 dual power master cylinder, front spindles and disk brakes on my '64 driver years ago before all the conversion kits. They'll stop the car very quickly. You will need a brake proportioning valve to reduce the pressure to the rear brakes.

Problem with using a '67 dual power master cylinder on a 63-4 is that the nose end of the master cylinder will set too high and the hood won't close. The off the shelf conversion kits should eliminate the hood clearance problem.

You might check for conversion kits some of the NCRS brake vendors such as; CSSB http://www.cssbinc.com/, Corvette Central http://www.corvettecentral.com/ etc.

I converted my 64 Fuelie to four wheel discs about five years ago. I sourced 67 disc brake suspension used parts and built up the system. I have 64 PB booster with 65 manual brake master cylinder (1" bore) so it is a single circuit system. This system has worked well for me ( & obviously no problem with my original KH knock offs).

Ruud,

If you already have a 63 booster, keep it. Make a few shims that go behind the top holes on the bracket. I suggest a plate with two holes drilled in it.

You need to shim it out just enough to lower the angle of the booster.

I have rebuilt a lot of 63 boosters. I have had to bend the actual bracket on the booster a few times to make sure the bolt head does not hit the hood.

I am sure a 65 master cylinder might even work out for you. I will go out tomorrow and see if I can get it to work.

My booster just happens to be off my 63 right now.

Truth is: you might be better off going with all four or not doing it at all. That way you can use a standard proportioning valve and everything else off the shelf.

Just an idea.

I will let you know what I find on the booster. I have another 63 booster that is apart. Maybe I can work with it a bit to help things come together.

You could always get an original 63 Z-06 master cylinder. LOL

Best of luck,

Monte
