My 73 3500s (96000k) performed admirably for two 500k journeys (despite the "Armstrong Steering" which made it a handfull on some of NZ's winding roads) although it was a pleasure to drive elsewhere. Shortly afterwards it developed a leak inthe rear brakes. This is understandable as the vehicle had little use over the past ten years (although prevously owned by an an enthusiast). I consulted the reliable mechanic to whom I entrust my vehicles. His previous experience was changing the rear brake pads on a P6. Which, I understand is a 2000 which is run -ahem- on aviation gasoline. After examining the vehicle he concluded that the only way to do the job properly was to (a) disconnect the rear brake hose (b) drop the drive shaft and © jack the rear of the vehicle up leaving the suspension behind. He completed the job in approximately four hours and expressed the hope that he would not have to do it again. P.S. I obtained a re-conditioning kit from Scottsold autorubber. I received with the car a Rover Repair Operation Manual and a new set of rear brake pads which appear to originate from some obscure (and un-named) EU source. P.P.S. My mechanic describes my P6 as a "true classic".
