The servo used in the MK3 Mini will fit into all models and works great! If you still have drum brakes don't ignore this information. A servo on drum brakes does wonders for stopping and if a future disc brake conversion is planned, a servo is a good first step! Contains servo 13H7939 a kit including mounting brackets and lines. If you have ever driven a car with one of these Servos installed you would never want to be without one! Technically speaking a servo does nothing to help the brakes. What it is really designed to to is help your leg muscles activate the brakes quicker and harder! But when installed it sure makes the car stop faster and feel a whole lot more confident when driving. This special kit from and aftermarket supplier includes the Servo, mounting brackets, brake lines and instructions. Although these are Mini servos, they can be retrofitted to any British hydraulic brake system….how about power brakes on a Morris Minor?!
I am having a problem with brake master cylinder (mounted to brake servo) at my Morris Mini Cooper S1300 (1275 engine) 1975. What part do I need for this project?
I’m converting my 81 MK4 to Cooper S discs.
The car has a split brake system.
Which servo should I use or do I even need one?
The servo is intended to work on the front brakes only.
