The Kelsey-Hayes Disk Brake Swap Thread

HELLO 57DODGED100,

Thank you for your post, super helpful. I know you have done much more research than me and have the actual hands-on experience… Because I am putting newer parts ‘72 on an older car ‘65 I need to confirm a few things… Thank you for your help.

Question about your choice of the Master Cylinder (MC36406) for the drum to disc brake swap project. I have a 1965 Valiant, 225cid. I am planning to keep the 5x4” bolt pattern and the rear 10” drums. My donor parts are from a 1972 Dart.

If I look up the Master cylinder used on the 1972 Valiant or Dart, 225CID, with front discs and rear drums, RockAuto lists the RAYBESTOS Part # MC36426, Professional Grade; Bore Size=1 1/32".

The original Master Cylinder on the 1965 Valiant was a very small BENDIX system (see RockAuto part # 11096).

Is there a big difference between the Raybestos Master Cylinder MC36406 you used and the other MC36426. I am thinking I should just stick with what you used… but unsure.

The original Master Cylinder (Bendix 11096) has an intergraded pushrod. Do I need another part or adaptor to use the newer MC36406?

My goal was to avoid replacing the brake lines, but the original equipment master cylinder has two outlets in slightly different configuration than the MC36406. Do I just bend (very carefully) the brake lines to meet the new MC36406?

Thank You
Acatl
