Brakes with the shakes
I read the email from Trevor Brereton about the intermittent shudder in his 2005 BA XR6 and thought it worth sharing my story, as I had the same issue. It became so bad you would have sworn a tyre had delaminated. I took the car to my dealer and they had no suggestions. As an ex-mechanic I replaced the brake rotors and pads, balanced tyres, etc. I spotted a comment where a guy had found his brakes were getting hot on a long run when he wasn’t using the brakes at all. Ford had told him to replace the brake booster, but the clever chap tried backing off the rod between the booster and master cylinder a few turns and it fixed the problem. I did the same and it’s dead easy to do, just undo the two nuts holding the brake master cylinder on, undo the lock nut on the push rod and wind it in a couple of turns, do the lock nut up and refit the master cylinder. You don’t need to remove the brake pipes.

A number of people contacted us about this issue, all pointing to the brakes as the root cause. From what we know the brakes don’t fully release after they’ve been applied and this leads to them heating up and the disc distorting, causing the vibration. Some suggested replacing the brake booster, others, like you, suggested adjusting the rod between the booster and the master cylinder.
PULL ANOTHER ONE
From new, my 2011 3.0-litre auto Nissan Patrol has exhibited very poor power in second gear when towing my 2200kg caravan up hills. My previous Patrol, also a 3.0-litre auto, would pull the van up the same hills with comparative ease. I had it dyno tested and it showed a maximum of 80kW at 3700rpm and 270Nm at 2100rpm. My dealer has tested my vehicle in conjunction with Nissan and says all is fine, and Nissan has now instructed the dealer to not perform any more work on the car. I have offered to take a dealer rep for a drive to show them the problem actually exists, but they say they are unable to do that. To make matters worse this vehicle consistently uses about 21 litres/100km whereas the previous one returned about 17 litres/100km on the same trip. What can I do?

From what you say it would appear the engine output is below what it should be, and the high fuel consumption would seem to reflect that. The output should be 118kW at 3200rpm and 380Nm at 2000rpm. Your idea of having a Nissan rep ride with you as you demonstrate the problem is a good one.
Late last year my 2001 Holden Astra was running well, but badly in need of servicing and the timing belt needed replacement (122,000km).
