panzer wagon vibration (NLC)

[BiggestNizzy]

I have started to get an intermittent vibration at the back of the beemer, it only happens on motorway and my initial thinking is the back brakes.

When it's happening and I jab on the brake I can feel it through the pedal and it reduces it for a little while but it comes back.

After a while it goes away.

Any ideas ?

Not really no.

Wheel nuts tight?

Look over the discs look for any patches that look different. Had this on the porker it's what is traditionally called warped disc but it's just a bit of the disc surface coating coming to bits. I wire brushed mine then gave them a real hammering about 5000 miles ago and it's been fine since.

Wheel nuts are tight:D

I have been racking my brain and I am thinking that maybe it's handrake related.

when I am on a hill and I release the handrake it takes 1/2 a second to release. also when parking up if I pull the handrake on I get alot of travel but if I release and pull it back up I get a normal amount of travel.

This symptom rings bells in my head about aspects of the rear drive/axle. That's all I can really remember but might be something to look up?

Sorry I can't be more help.

No.

But let me know if/when you find out. Mine is doing something similar, but can't yet find anything.

Sounds like a sticky caliper which has caused high spots on the discs?
