Brake Servo Filters Replacement

[98-110]

I'm wondering how often these filters should be changed - Def 300tdi in my case.
It seems a fairly fiddly job so I'm not over keen to do it unless necessary.

Would it be ok to do it just when the brake master is overhauled
or should it be done more often?

Thanks

colour me dumb, but where the hell is it ?

If its like an RRC, its in the opening that the pedal pushrod goes thru and is made of felt ?

Well Rick, i'm not sure whether you're just telling me you've never change them, so for the record, they are on the pushrod probably where it enters the servo housing. [Def Workshop Manual Sect 10, p50]

They are in the pedal box and so inside the car; safe from dust and water.

yep, never changed one, obviously :D

cheers.
