My pedal pad fell off the brakes last night and I think it may be time to replace the master cylinder. I have a twin circuit master cylinder lying around that I was thinking of reconditioning and putting on the car. As far as I know all I need to do do convert to twin circuit brakes is install the master cylinder and replace the T-piece behind the clutch slave cylinder with two separate connectors to separate the front and rear brake circuits. Then the standard bias valve on the rear subframe should still do its job. And I'll connect the brake booster to the front circuit only.

Can anybody see a problem with doing this? I figure that assuming the master cylinder works then it would have to be an improvement safety wise. A while back I had somebody tell me that the master cylinder off a late model Rover (with the booster) will fit on. Can anybody confirm/deny this? I thought the firewall itself was different on the late model cars for the integrated-booster type master cylinders.

A lot of work for no real gain IMO

If you get a leak in one circuit, you won't have brakes anyway. Brad couldn't bleed his up until he replaced both rear wheel cylinders.
The tandem MCs were fitted "to satisfy ADR requirements". :wink:

Because they don't seem to work like later ones on modern cars?
The tandem feature is illusory.

Is this just the non booster type on clubmans, or does it include the boostered type on rovers ?

I'm talking Clubby ones, 1977-78.
