No, I haven't felt the need - I've got stock master cylinder and booster and drum brakes - I haven't really noticed longer pedal travel or any downsides at all.@jonbills I'm almost ready to start installing the front GTR Calipers, carriers and new discs (found out all the brake lines are corroded and need replacement from the master cylinder back to each wheel! So working on this first).
Do I need to do anything with the Servo and/or Master Cylinder if I am to retain the drum brakes for the moment?
