Hi, new to the group here... and new to Range Rovers.
I purchased a 1995 RR LWB last week. I've noticed that, when first started, the brake booster compressor runs for 5-10 seconds before the brake light goes out. And it's a bit noisy when running. Just curious if this is a normal operation or indicative of a leak somewhere.
Any info would be appreciated, I'll probably have lots more questions.
I think you mean the air suspension compressor? The brake lioght does stay on for a few seconds. Mine was noisy, but worked fine.

If it's an ABS one, then you have an electric pump which pressurises the brake system. There's a pressure accumulator on the thing (a bit like the citroen system). If it's parked for any length of time, the pressure gradually drops and when you start up it runs the pump 'til it's back up to pressure. At some pressure below nominal the brake-fail light goes out. If you actually depressurize the thing completely (apply the brakes lots with the ignition off, for example) then it runs the pump for about a minute, probably, to repressurise it.
same system on my 4x4 sierra...
No, I don't think it's the air suspension unit, The air bag suspension have been replaced with springs. and the compressor (located under the hood on the fender on the drivers side) seems to feed the brakes as I loose brakes if I unplug the electrical to it.
But as I said, I'm new to RR's. Thanks for all advice.
