This is a 3:1 ratio servo unit, which can be fitted to 120 and 140 cars with either drum or disc brakes. It can also be used to replace the troublesome Lockheed-type unit on XK150s for greater braking ratio-to pedal input. It is simple to fit and immediately gives a greater feel of safety when braking.

N.B. For 120 or 140s with front disc brakes, we only use the servo assistance on the front brakes.

Price for the servo unit with mounting plate and vacuum pipe £249.50.

(All fittings are available for a range of conversions)
