Well I've never seen it done that way. Disk master with drums on the car.
Going the other way around with disks on the car and a drum master, the
brake pedal feels like an on/off switch. Hard to modulate.
Disk brakes require less fluid to be moved in order for the friction
material to contact the rotor. So the disk brake master has a narrower bore;
thus an inch of pedal travel moves less fluid through the lines. In order to
move enough fluid to push the drum brake shoes out to the drums, I would
expect a lot of pedal travel before the brakes bite, if I had a disk brake
master on a drum-braked car. I'm not sure "effort" would change, but they
might seem alarming on the road, as your foot went to the floor before
anything happened.
I did both changes at once. Disks are an improvement.

Subject: Re: Bugeye Group..... Re: Drum to Disc Conversion
On a similar note,
I am wanting to change the master cylinder on my MK 1 midget to the separate
clutch & brake setup. I am planning on putting disc brakes on soon. Will
there
be a considerable increase in pedal force required to make the drum brakes
work with a newer master??
or will it remain about the same?
Thanks
