1965 Wildcat - Converting from single to dual master

[65_wcat]

I'm hoping someone out there has already done this:

I'd like to convert my single master cylinder(Delco Moraine)to a dual. What is involved in making such a conversion?

I believe the first year to use the dual master system was 1967. Can I use the master from that year? I think they used a Bendix unit. Do I have to change the power booser as well?

Thanks.

simple- i've done about 9 of theses conversions.

use a 67-69 master- you must use a bendix master

you do NOT have to change the booster.

you MUST use a proportioning vale from a 67-69 drum-drum full size, or a 67-69

skylark- the conversion will NOT work if you dont put in this valve

if you have questions, email me buickguyjon1@sbcglobal.net

You definitely do not use a proportioning valve but a distribution block. Proportioning valve are only if you have front disk brakes. I have a spare 67 distribution block you can have for $20.

Thanks to both of you for the reply.

Larry,

I was surprised to see that I needed a proportioning valve too. Seemed odd for drum brakes.

I would be interested in the distribution block. If you don't mind, please e-mail me with your address (gjh6801@cs.com) and I'll send the money.

Also, any other pitfalls I should be aware of when I start the conversion?

Thanks again!

guys- dual master brake systems DO use a proportioning valve- the proportion the brakes 70/30 front/rear- they are not the same as a distribution block- those do not have a valve to keep one set of brakes working if you loose one side. They dont work the same as disc/drum, but they are proportioning- most of your pedal feel comes from the rear brakes, so they must be. hope this helps
