I've just had the 'Troll MOT'd, serviced, the front brake pads and disks replaced and the caliper guide pins removed, cleaned up and greased both front and back. On the move, the brakes work silently and as well as brakes ever work in a Patrol. I'm about as convinced of that as I can be.
All, however, is not *quite* hunky dory. As an old fart who, in the dim and distant, used to drive grot boxes, I've always had a habit of standing on the brakes when I first get into a car, just to make sure that the pedal fights back. Starting maybe a few months back, very occasionally (once or twice a week?) when I stand on the brake pedal before starting the engine, a kind of (quite loud) grinding noise comes from somewhere at the front which I can feel being fed back through the pedal. Most days, it doesn't do it. When it does do it, it only does it once. If I pump the pedal again, it behaves normally - no noise and a solid feel, exactly as you'd expect. After I've started the engine, the brakes behave normally. I've no reason to suppose that there's a problem with the brake master cylinder and even if there were, I cannot imagine it making this kind of noise.
My experience of taking motors to bits and diagnosing faults comes mainly from the days when cars had drum brakes, distributors and carburetors and other such ancient stuff - so I can only speculate about whether the ABS system might cause this behaviour - or even indeed about whether the behaviour is even abnormal. The ABS light on the dash is, though, behaving normally.
In my experience, when something makes an unexpected noise or behaves abnormally, it usually means that something is about to break and that worrying about it is probably justified. Have i got a problem or am I just being paranoid? If you think the 'Troll has a problem, what do you think it might be?
Thoughts?
Cheers
